FX Blue Personal Trade Copier for MT4 - User guide

Author: fxblue

1Overview of the Personal Trade Copier

1.1Purpose of the trade copier

The Personal Trade Copier duplicates trades between two (or more) copies of MT4 or MT5 running on the same computer. You place trades in one copy of MT4/5, and these are replicated almost instantly in the other copy of MT4/5. The trade copier duplicates both manual and automated trading.

There are separate versions of the software for MT4 and MT5, but they are fully compatible with each other. You can send trades between any combination of MT4 accounts and MT5 accounts.

In MT5, the copier can be used on both hedging and netting accounts, but there are special steps which you need to take on netting accounts.

You can copy from multiple instances of MT4/5 into a single receiver, and vice versa, by running more than one copy of the sender and receiver.

The sending copy of MT4/5 does not need the ability to place trades. Therefore, the sending copy can be logged in using the read-only MT4/5 "investor" password.

1.2Licence

Unless otherwise specified in writing by FX Blue, this software is licensed for personal use only. You are not allowed to distribute it to other people, regardless of whether or not money is changing hands. You only have a licence to use the software if you, personally, downloaded it from our website.

You are not allowed to use the Personal Trade Copier as the basis of a commercial trade-copying service. You can use it for family and friends, but you are not permitted to use it to copy trades onto other people's accounts in return for any sort of payment. You should use our Trade Mirror instead.

The software is provided entirely at the user's risk, and you should check it thoroughly before deploying it on computers trading real money. FX Blue accepts no responsibility whatsoever for any loss of any kind caused by installation or use of the software.

1.3Frequently Asked Questions

1.3.1Can I copy to/from more than one account?

Yes! Please see section 2.4 for setting up multiple senders or multiple receivers.

1.3.2Can I trade from my phone?

Yes, you can trade from your phone provided that you are also simultaneously running the Personal Trade Copier in a desktop installation of MT4/5. Any trades which you place from your phone will then be seen by the desktop version of MT4/5, and copied.

1.3.3Should I use the Trade Mirror or the Personal Trade Copier?

Wherever possible, you should use the Personal Trade Copier instead of the Trade Mirror. The Personal Trade Copier is easier to set up, and it copies trades faster because it does not need to send signals over the internet.

If you have control over all the accounts which are receiving trades, then you should generally use the Personal Trade Copier. For example:

  • You are copying trades to other MT4/5 accounts for members of your family
  • On your computer (or VPS) you run an installation of MT4/5 for each member of your family
  • Your family members can still run their own copies of MT4/5 (or trade through their phones). There can be multiple copies of MT4/5 simultaneously logged in to the same account from different places.
  • You use the Personal Trade Copier to copy between the installations of MT4/5 on your single computer.
  • Your family members receive your copied trades without preventing them running their own copies of MT4/5 logged in to the same accounts.

But please also bear in mind the licence conditions. You are not allowed to use the Personal Trade Copier as part of a commercial service. You must use the Trade Mirror instead.

1.3.4Can I log in to the broker account using the read-only "investor" password?

The Sender account can be logged in to MT4/5 using the read-only "investor" password, because the Sender EA does not place trades.

The Receiver account cannot be logged in using the read-only "investor" password. The Receiver EA obviously needs to place trades, and so MT4/5 must be logged in using the master account password.

1.3.5Can I copy between demo and real-money accounts?

Yes, you can copy between any combination of demo and real-money accounts (demo->demo, demo->live, live->demo, live->live).

1.3.6Can I copy between accounts from different brokers?

Yes, you can copy between any MT4/5 accounts with any MT4/5 brokers.

However, if you are sending signals between different brokers then it increases the probability that you will need to change two settings in the copier:

Change the slippage tolerance, because of price differences between the brokers.

Add translations for different symbol names on the two brokers.

1.3.7How do I trade the same lot size on the sender and receiver?

By default, the copier will not necessarily trade the same lot size on the receiver as on the sender. Its standard behaviour is to adjust the lot size based on the relative equity of the two accounts.

If you want to trade exactly the same lot size, even though this may imply very different levels of risk on the sender and receiver accounts, then you need to do the following:

Turn off UseRiskFactor by setting it to zero

Set LotSizeMultiplier to 1

Please see the section of this guide about lot sizing for more information.

2.1Installing the trade copier

You need two (or more) copies of MT4/5 installed on the same computer.

To create multiple installations of MT4/5 from the same broker, use the Settings button at the start of the MT4/5 installer and choose a new directory for each installation.

The app installer from our website lets you choose multiple copies of MT4/5, and then copies the sender and receiver EAs into MT4/5.

You need to restart MT4/5 in order for its Navigator list to update - or you can right-click over the Navigator and use the "Refresh" option.

2.2Running the sender

In the sending instance of MT4/5 you open a new chart for any symbol and add the "FX Blue - TradeCopy Sender" EA to the chart, by double-clicking on it in the Navigator list or dragging it onto the chart. The EA's "Allow DLL imports" setting must be turned on.

You do not need to run multiple copies of the EA on charts for each symbol which you trade. You should only run one copy of the sender EA, on any chart. This will duplicate all trades for all symbols.

The sender EA does not need the ability to place orders. Therefore, it can be running on an account which is logged in using the read-only MT4/5 "investor" password.

2.3Running the receiver

In the receiving instance of MT4/5 you open a new chart for any symbol and add the "FX Blue - TradeCopy Receiver" EA to the chart, by double-clicking on it in the Navigator list or dragging it onto the chart. The EA's "Allow DLL imports" setting must be turned on.

You do not need to run multiple copies of the EA on charts for each symbol which you trade. You should only run one copy of the receiver EA, on any chart.

In MT4, you can also optionally run copies of the Receiver-Worker EA. This can allow MT4 to copy trades faster by processing multiple actions at once.

2.4Multiple senders and receivers

A sender and receiver are identified by a channel name, which you can control using the EAs' parameters. The default channel name is "TradeCopy".

There should only be one sender EA and one receiver EA using a channel.

A single copy of the sender EA can broadcast on multiple channels, but each receiver EA can only listen on a single channel.

If you want to send trades from one copy of MT4/5 to 3 receiver copies of MT4/5, you should do the following:

  • In the sender instance of MT4/5, you run one copy of the sender EA. You set the Channel parameter in the EA to a comma-separated list of the channel names which the sender should use. For example: Channel1,Channel2,Channel3. (Alternatively, you can also run three copies of the sender EA, each broadcasting on one of the channels.)
  • In each receiver instance of MT4/5, you run a copy of the receiver EA and configure each one to use one of the three channels you have set up in the sender.

If you want a single copy of MT4/5 to receive trades from 3 senders, then you should do the following:

  • In the receiver instance of MT4/5, you run three different copies of the receiver EA on different charts, using different channel names.
  • In each sender instance of MT4/5, you use one of the three channels you have set up in the receiver.

Each receiver EA running in a copy of MT4/5 should use a different magic number for its trades. You should either leave the receiver EA's MagicNumber parameter set to zero, in which case it will automatically choose a magic number based on the channel name, or you should manually set each receiver EA to use a different magic number.

2.4.1Distinguishing between multiple instances of the Copier

If you are running multiple instances of the Copier then you can make it easier to distinguish between them in two ways: by setting a description (which is displayed in the top-right of the chart) and by changing the background colour.

Both the Sender EA and Receiver EA have UserDescription and BackgroundColour settings.

2.5Testing the trade copier

The following screenshots are examples of the Sender and Receiver running successfully:

(The full-chart background is designed to reduce support queries from new MT4/5 users who otherwise try to run more than one EA on the same chart. The colour can be changed using the BackgroundColour setting in each EA.)

Once both the sender and receiver EAs are running, the receiver should shortly receive a "heartbeat" message from the sender and update its status on screen.

Both EAs display their current status in the top-right of the chart. If no status is visible, please see the troubleshooting notes below.

2.6Performance on VPS systems

On some low-spec VPS systems the Copier may use too much processing power, particularly if there is a large number of open trades on the sender account.

You can reduce the Copier's processing needs by increasing the TradeWatchFrequencyMS parameter in the sender EA. The default value of this parameter is 50. Increasing the value to e.g. 100 will reduce processor usage, typically without any significant difference in copying speed.

2.7Moving the Copier to a new computer

In most cases you can move the Copier to a new computer simply by installing the software on that computer; shutting it down on the old computer; and starting it up on the new one.

To avoid any possible problems, it is preferable to start the Sender first; wait until MT4/5 is definitely connected to the broker and has received the list of open positions (if any); and then start the Receiver.

If you have turned on the UseOriginalOrderComments setting then, as described below, you will also need to copy the contents of the MQL\Files directory from the old computer to the new one. If UseOriginalOrderComments is turned on, then the relationship between ticket numbers on the sender and receiver has to be tracked using a file on disk, and this must be transferred to the new machine.

The same applies on MT5 netting accounts: you need to move the copier's tracking file in MQL5\Files to the new computer.

You can test the new computer by logging in the receiver copy of MT4/5 using the read-only investor password. This will prevent it being able to open or close trades. You can use this to check that the connection to the sender is successful, and that it is not trying to close any existing open positions, and then log back in using the normal master password once satisfied.

3.1Trade placement and closure

The sender EA sends a message to the receiver EA as soon as it spots that there is a new open order in its copy of MT4/5.

Note: in MT5, you can start copying new trades in the sender as soon as they are sent to the broker, before they are confirmed, by turning on CopyMT5WorkingMarketOrders.

The receiver EA will then attempt to place the same trade. Transmission between sender and receiver is more or less instant; the time taken to copy the trade should depend almost entirely on your broker(s), not on the speed of transmission between the two EAs.

The same applies to trade closure. As soon as it spots that a previously open order has been closed, the sender EA tells the receiver EA to close its trade.

By the default, the Copier ignores any positions which are already open when it starts running. It is possible to copy these orders as well, but you need to adjust the system's slippage tolerance.

3.1.1Speed of processing on the receiver

Once the receiver gets a signal from the sender, it should make a request to its own broker almost immediately. The overall speed of trade copying is controlled almost entirely by the speed of trade placement by the broker (including network latency to the broker), not by the internal speed of the copier.

The copier's logs will show where any delays are occurring. The copier will record the following process:

Detection by the sender EA of a new trade on its account

Message arriving in the receiver from the sender

Instruction by the receiver to its broker

Confirmation of the new trade on the receiver by the broker

However, there is a special consideration in MT4 (only, not in MT5). Unless you use the optional Receiver-Worker EA, MT4 can only carry out one trading action at a time, and the receiver EA cannot do anything else while it is waiting for the broker to accept or reject an instruction. If two new signals arrive in the MT4 receiver simultaneously, the receiver EA cannot start working on the second one until its broker accepts/rejects the first one.

3.1.2Stop-loss and take-profit on the receiver

The stop-loss and take-profit on the receiver's trade are only a safeguard in case the connection with the sender is lost. Under normal circumstances, the receiver's trade will be closed as soon as the sender's trade is closed. The receiver's s/l and t/p are only used if either (a) the connection with the sender is lost and no close instruction is received, or (b) price differences between brokers mean that the receiver's s/l or t/p is hit before the sender's s/l or t/p.

As a result, please note the following:

The optional FixedSLPips and FixedTPPips parameters specify a maximum value for the stop-loss and take-profit. Trades can still be closed when the sender's trade is closed, before the s/l or t/p is hit on the receiver.

The cash-risk lot-sizing modes therefore specify a maximum cash risk (because they use the sender's stop-loss or FixedSLPips). The s/l controls the maximum amount of money which the receiver can lose, but the receiver's trade can still be closed at any time and at any profit/loss, when the sender's trade is closed.

If you want the receiver to ignore trade-closure on the sender, and only to close trades when the s/l or t/p is hit on the receiver, then turn on the IgnoreAllExitSignals parameter.

3.1.3Slippage tolerance and market entry

By default, there is a limit on the price difference which the copier will accept between the sender's price and the receiver's price - controlled by the AllowSlippagePips setting.

If the price difference between the sender and receiver is larger than this, the receiver will try to get the sender's price by placing a pending limit order instead of buying or selling at market. Note: the broker can have a restriction on the minimum distance between a pending entry and the current market price. A trade can be rejected (MT4 error #130) if the price difference is larger than AllowSlippagePips but smaller than the broker's stop-level.

You can change the copier's behaviour in four ways:

Increase or decrease the AllowSlippagePips tolerance

Turn off the PlaceLimitOrderIfSlipped setting in the receiver. If the price difference between sender and receiver is larger than AllowSlippagePips, the receiver will reject the trade rather than trying to place a pending order.

Turn on TradeAllOrdersAtMarket in the receiver. This tells the receiver to ignore the AllowSlippagePips setting, and to accept any price difference between sender and receiver.

Turn on BroadcastAllOrdersAtMarket in the sender. This has the same effect as TradeAllOrdersAtMarket in the receiver.

3.1.4Existing orders which are open when the Copier starts

By default, the system will not copy any positions which are already open when it starts running. It will only copy new positions which are opened once the software is active.

You can change this behaviour by turning on the AllowExistingOrders in the Sender EA. You must also start the Receiver EA before you start the Sender EA.

However, there can be substantial differences in price between the sender and the receiver (because the sender's position was opened minutes or even hours ago, whereas the receiver's position is being opened right now). In order to copy existing positions, you will need to change the slippage tolerance.

3.2Heartbeats

Note: the heartbeat period does not control how quickly orders are copied. Open and close messages are always sent immediately, and processed as quickly as possible.

The sender EA sends a periodic "heartbeat" message, every 10 seconds by default. This states which orders should still be open. If a receiver misses a trade-closure instruction, e.g. because its copy of MT4/5 is not running at the time, then it should close the order when it next receives a heartbeat from the sender.

Changes to a trade's s/l or t/p are also sent in the heartbeat message. Therefore, there may be a delay of up to 10 seconds between the s/l or t/p changing in the sender's copy of MT4/5 and the receiver making the change. However, if the trade is closed out on the sender within those 10 seconds because the s/l or t/p is hit, that should lead to an immediate close instruction being sent to the receiver.

Changes to the entry price on a pending order are also sent in the heartbeat, and therefore updated within 10 seconds.

3.3Pending orders

By default the trade copier does not send pending orders. It only sends a message to the receiver once a pending order is filled and turns into a buy or sell order.

Copying pending orders can be disadvantageous and dangerous. We recommend that you do not do this:

  • If the receiver's spreads are better than the sender's spreads then, assuming that slippage averages out to be neutral, it is better for the receiver to enter at market when the sender is filled than to enter (and exit) at the sender's price.
  • If the receiver's spreads are worse than the sender's spreads then the receiver can be filled without the sender being filled, and there can be an unmanaged trade on the receiver.

For example, let's say that you are trading the breakout of yesterday's range, and you have a buy-stop at yesterday's high. This could get triggered on the receiver without being triggered on the sender, because of either slight price differences between the two accounts, or wider spreads on the receiver. If the price then retraces, the sending copy of MT4/5 will be unaware that the receiver has a trade which needs to be managed, but the receiver will have an ever-increasing loss and will not be receiving any instructions to close the position.

However, you can configure the trade copier to send pending orders by turning on the optional IncludePendingOrders parameter.

You can then use the RequireSenderFillWithinMinutes parameter to limit the risk at the receiver end. If the receiver's order is filled, but the sender's order remains pending, then the receiver can be configured to close its order after this number of minutes (ignored if zero).

Note: you cannot use IncludePendingOrders on an MT5 netting account.

3.4Lot sizing and risk

The software's default settings (UseRiskFactor=1) will trade the same relative lot size on the sender and receiver. For example: the sender trades 0.50 lots and has equity of $10,000; the receiver has equity of $2000 and trades 0.10 lots.

The software has several different lot-sizing modes which you can choose from, using the following settings. Only one of these settings should be non-zero. These are processed in order: for example, EquityPerLot is only used if UseFixedLotSize, UseRiskFactor and LotSizeMultiplier are all set to zero.

UseFixedLotSize

UseRiskFactor

LotSizeMultiplier

EquityPerLot

BalancePerLot

CashRiskFixed

CashRiskEquityPercent

CashRiskBalancePercent

NotionalDepositVolume

To repeat: only one of the above settings should be turned on. All the other values should be set to zero.

3.4.1Trading a fixed lot size on all orders

You can trade a fixed lot size on all orders, regardless of what volume the sender trades, by using the UseFixedLotSize parameter (and turning off the other modes). For example, setting UseFixedLotSize to 0.25 will trade 0.25 lots on every order regardless of whether the sender trades 0.25, 0.01, 1.53 etc.

3.4.2Trading the same lot size as the sender, or a multiple of the sender's lot size

You can trade a multiple of the sender's lot size using the LotSizeMultiplier parameter (and turning off the other modes). For example, a value of 0.5 means that the receiver will trade half the sender's lot size, and a value of 3 means that the receiver will trade triple the sender's lot size.

A value of 1 for LotSizeMultiplier (and turning off the other modes) means that the sender and receiver trade exactly the same lot size.

Please note that trading the same lot size does not mean that the receiver is taking the same amount of risk. For example, the sender and receiver both trade 0.10 lots, but the sender has equity of $5000 and the receiver has equity of $2500. The receiver is taking double the risk of the sender.

3.4.3Trading the same relative lot size (based on relative equity)

You can trade the same relative lot size on the sender and receiver using the UseRiskFactor parameter (and turning off the other modes). This is the software's default setting.

A value of 1 for UseRiskFactor means that the lot size will be adjusted between the sender and receiver based on their relative equity (converted to US dollars on both sides, if necessary). For example, if the sender has equity of $5000 and trades 0.20 lots, then the receiver will trade 0.10 lots if it has equity of $2500.

You can adjust the relative risk by increasing or decreasing UseRiskFactor; a value of 1.5 means that the receiver will take 50% more risk than the sender.

For example, if the sender's equity is $2000 and the receiver's equity is $4000, and UseRiskFactor is set to 1.5, then the receiver will trade three times the lot size of the sender - i.e. 4000 / 2000 x 1.5 = 3.

3.4.4Fixed lot sizes based on account equity or balance

You can trade a fixed lot size on the receiver based on its equity or balance, ignoring the sender's lot size, using the EquityPerLot or BalancePerLot parameter (and turning off the other modes).

The EquityPerLot parameter specifies how much equity the receiver must have in order to trade 1 whole lot (and the BalancePerLot carries out the same calculation in relation to the balance instead of the equity).

For example, if EquityPerLot is set to 50000, and the current account equity is 10000, then the receiver will trade 10000 / 50000 = 0.20 lots.

3.4.5Lot sizing based on maximum cash risk

You can configure the receiver to risk a specific cash amount, or a percentage of your account, using the CashRiskFixed, CashRiskEquityPercent, or CashRiskBalancePercent parameter (and turning off the other modes).

CashRiskFixed: specifies a fixed cash amount to risk per trade, e.g. $100

CashRiskEquityPercent: specifies a percentage of your account equity to risk, e.g. 2.5%

CashRiskBalancePercent: specifies a percentage of your account equity to risk, e.g. 2.5%

In order to use any of these settings, the sender's order must have a stop-loss, or you must override this by using the FixedSLPips parameter to set your stop-loss on each trade.

The receiver then adjusts the lot size of the trade so that hitting the stop-loss causes no more than the specified cash risk.

For example:

You set CashRiskEquityPercent to 1 (meaning 1% of your equity).

Sender's stop-loss is at 50 pips from entry (or you set FixedSLPips to 50).

Your account equity is $10000.

The receiver calculates that a 50-pip stop-loss represents a loss of $500 per whole lot.

You have asked to risk 1%, i.e. $100 of your equity

Therefore, the receiver trades $100 / $500 = 0.20 lots, risking a maximum of $100 if the s/l at 50 pips is hit.

Please note that these risk settings are maximums: trades can be closed at any time when the sender's position is closed, before the fixed stop-loss is hit.

3.4.6Mini, micro and cent accounts

The software automatically handles "micro" and "mini" MT4/5 accounts (where the lot size is 10K or 1K instead of the usual 100K).

The software cannot automatically detect "cent" accounts (where the lot size is 100K, but meaning 100,000 cents rather than $100,000). By default, the receiver's lot sizes will be 100 times too large on these accounts. You can either turn on the CentAccount setting, or you can divide the values for UseRiskFactor or LotSizeMultiplier by 100 (e.g. setting them to 0.01 instead of 1.00).

3.4.7Minimum lot sizes

Conversion using settings such as UseRiskFactor or LotSizeMultiplier can lead to a lot size which is smaller than the broker's minimum. The receiver will not place these trades unless you turn on the RoundUpToBrokerMinimum setting. (This rejection will be included in the information which is written to the MT4/5 Experts log.)

In addition, you can use the MaxLots and MinLots parameter to put a cap on the lot sizes which the receiver trades. For example, setting LotSizeMultiplier to 2 with MaxLots set to 0.50 means "trade double the sender's lot size, but never more than 0.50 lots".

3.5Broker symbol names and suffixes

Symbol names are not standardised and can vary between broker accounts. For example, the EUR/USD fx pair may be EURUSD on one account and EURUSD.xyz on another. An equity index such as the DAX may be referred to as DE30, GER30, .DAX, .DE30, [GER30] etc.

In addition, some accounts may contain more than one version of each market on their symbol list - for example, both EURUSD and EURUSD+. When it receives a trade for EUR/USD, the copier needs to know which symbol it should use - and which version, if there is more than one.

The copier should almost always be able to handle fx pairs without manual overrides to its settings

The copier will often be able to handle metals, oil, and equity indices, but may require manual overrides to its settings

Other markets, particularly individual equities such as Apple or Google, will almost always require manual overrides unless you are copying between two accounts of the same broker.

FX pairs are handled by the ForexSymbolSuffix setting. The copier can usually auto-detect this, and it will tell you if it cannot. If you are changing this setting manually, you need to use the suffix for the fx symbols which you want to trade. For example, if you want to trade EURUSD.xyz, GBPUSD.xyz etc, then you set ForexSymbolSuffix to .xyz

Non-fx markets require entries in the CustomSymbolMappings list. This tells the copier how to translate from symbol names on the sender account to symbol names on the receiver account. For example, if the sender's name for the S&P 500 index is SPX500 and the receiver's version is .US500, then the entry to add to CustomSymbolMappings is:

SPX500=.US500

3.5.1Custom pip-sizes for symbols

By default, the software will use a pip-size definition based on the number of digits which the broker quotes in the price. For example, if the price is quoted to 2 or 3 decimal places then the software will use a pip size of 0.01.

You can override this for specific symbols using the CustomPipSizes setting. For example, you can set this to XAUUSD=1,GER30=1 to use a pip size of 1.00 on XAUUSD and GER30.

Entries in the CustomPipSizes list must exactly match the full symbol name on the receiver account (including any suffix).

3.5.2Custom volume multipliers for symbols

The software will automatically convert between normal and "mini" accounts (where the lot size for forex symbol is 10,000 rather than the usual 100,000).

However, some brokers have different contract sizes for CFDs. One broker may have a contract size for GER30 (Dax) of 1 whereas another has a contract size of 0.01. You can adjust the volumes from the sender for specific symbols using the CustomLotMultipliers setting.

For example, if the sender's DAX and CAC40 contracts are 100 times smaller than the receiver's contracts, then the following setting will adjust the calculation on the receiver to make the trades 100 times smaller. Entries in this list must exactly match the full symbol name on the receiver account, including any suffix:

DAX=0.01,CAC40=0.01

3.6Market execution

(Legacy information: some brokers use "market execution" where, in the past, it was necessary for an EA to send a trade and then send a separate instruction to add any s/l and t/p. However, in all recent releases of MT4 and MT5, EAs should now be allowed to send the s/l and t/p as part of their order-open. As a result, the old CloseOrdersImmediatelyIfSLFails setting has been removed from the copier.)

3.7Hedging vs. non-hedging

The copier can be used with both hedging and netting accounts on MT5. However, netting accounts require an extra setting to be turned on in the copier.

The copier cannot be fully used with FIFO/non-hedging accounts on MT4, because MT4 does not have proper netting accounts. If the sender opens a buy ticket and then a sell ticket (or vice versa), the first trade will be successfully opened on the FIFO/non-hedging account but the hedged trade will fail.

3.8Magic numbers

The receiver uses an order's magic number to identify which orders belong to it, versus which orders are from manual trading or other EAs running on the account. Therefore, magic numbers are not copied from the sender account.

The receiver EA uses the same magic number for all orders which it processes. By default, it automatically selects a magic number based on the channel name. You can choose your own magic number by setting the MagicNumber parameter to something other than zero.

If you trade multiple EAs on the sending copy of MT4/5, and you want each order in the receiving copy of MT4/5 to have a different magic number based on the magic number in the sending copy of MT4/5, then you can do the following:

  • Run multiple copies of the sender EA, and set the IncludeMagicNumbers parameter or the IncludeOrderComments parameter so that each sender only includes the orders from one of the EAs on the account. Each sender EA must use a different channel name.
  • Run multiple copies of the receiver EA (using the same channel names as in the sender EA). You can either leave the receivers' MagicNumber parameters set to zero, in which case the magic numbers will be different for each channel but will not match the sending copy of MT4/5, or you can configure each receiver to use the same magic number which is being used in the corresponding sender EA to filter the orders on the channel.

3.9Partial closes

The sender and receiver EAs are capable of handling partial closes.

However, this relies on brokers using the standard functionality of MT4/5. Partial closes will not be processed properly by the copier if the broker deviates from standard MT4/5 functionality:

On MT4, the copier expects a partial close to be identified by the order comment (e.g. "from #12345678")

On MT5, the copier expects the ticket number of a position to be unchanged following a partial close (i.e. ticket number remains the same, with reduced volume).

3.10Inverting trade direction

The receiver can be configured to invert the broadcaster's trade direction, turning buys into sells and vice versa. (This feature has been included at user request; we are not aware of any loss-making trading system which can be made profitable by inverting it.)

In order to use this feature you need to turn on the receiver EA's InvertTrades parameter.

In addition, you will also usually need to change the slippage tolerance. The price difference between the sender and receiver will, after inversion, be at least the size of the spread, and may well be rejected by the copier's default settings.

3.11Order comments

By default, the receiver uses the MT4/5 order comment to track the ticket numbers on the sender account. You can change this behaviour, and get the receiver to use the original comments from the orders on the sender account, by turning on the UseOriginalOrderComments parameter in the receiver.

Alternatively, you can use the UseCustomOrderComment parameter to use a fixed comment for all orders.

However, please note that these parameters have implications for disaster-recovery. If you turn on UseOriginalOrderComments or UseCustomOrderComment, then the ticket numbers on the sender account are tracked using a file on disk (in MT4/5's MQL\files directory). If this file is deleted - or is unavailable for some other reason, e.g. because you are starting up MT5 on a new computer in an emergency - then the receiver will close all its orders because it can no longer link them to the sender's heartbeat.

3.12Binary options

The Copier can handle any order which can be placed through MT4/5. This includes binary options where the broker has a plug-in allowing you to place binary trades using the features in MT4/5.

However, brokers' binary option plug-ins for MT4/5 often use things such as the order comment to specify the expiry for the binary option. In cases such as these, you will need to turn on the UseOriginalOrderComments setting, as described above.

3.13Controlling the Copier using MT4/5 Global Variables

You can block the Mirror from placing new trades using a Global Variable in MT4/5 (press F3, or choose Tools / Global Variables).

You can use this either as a way of controlling the Mirror manually, by creating and removing the Global Variable yourself, or you can have an automated system which uses the Global Variable to turn the copying on and off based on something such as account equity or performance.

The Copier is controlled by a Global Variable called Suspend-X, where X is the channel name. For example: Suspend-MySender. If a variable exists with this name, regardless of its value (zero/non-zero) then the Copier will ignore new trade signals arriving from the sender.

You can also use global variables to control the lot sizes used by the Copier (completely overriding the Copier's standard lot sizing). There are two options: per-symbol settings, and a global override. A global variable in the form CopierLotSize-<symbol>, such as CopierLotSize-EURUSD+, sets a lot size for a specific symbol. The setting CopierLotSize-All overrides the lot size for all symbols which do not have their own setting.

4.1.1Sender parameters: channel and heartbeat period

Server settings

Channel

The channel name(s) to use for communicating with the receiver(s). There should only be one receiver and one sender on each channel.A single sender EA can broadcast on multiple channels, which you specify by entering a comma-separated list of names in the Channel parameter, e.g. Scalp1,Scalp2,Scalp3. Channel names must not contain any of the following characters: / \ : * ? " < > |. In addition, the list must not include spaces between each comma-separated item.

HeartbeatPeriodSeconds

The number of seconds to wait between sending each heartbeat message

4.1.2Sender parameters: orders to include

Orders to include

IncludeSymbols

If not blank, a comma-separated list of symbols to include in the messages to the receiver. This must exactly match the broker's names, including upper/lower case such as EURUSDfx,GBPUSDfx. Trades for symbols which are not on this list are not included.

You can also start the list with ! to mean "all symbols are permitted except the following". For example:

!EURUSDfx,GBPUSDfx

IncludeMagicNumbers

If not blank, a comma-separated list of EA magic numbers to include in the messages to the receiver. For example, 0,1234,6789 will include manual orders (which have magic number 0), plus orders from the EA(s) which use the magic numbers 1234 and 6789.

You can also start the list with ! to mean "all magic numbers are permitted except the following". For example: !1234,6789

A further option is that you can set IncludeMagicNumbers to file:X, such as file:mylist.txt. The Copier will then read a list of magic numbers from a file in the MQL\Files directory, such as mylist.txt. This file can use several formats to specify the permitted magic numbers: one entry per line, entries separated by spaces, entries separated by commas. You can also include ranges of permitted magic numbers such 100-799

IncludeOrderComments

If not blank, a comma-separated list of order comments to include. For example, pivot,breakout will only include orders whose comment includes either "pivot" or "breakout". The match is case-sensitive. You can also match an exact order comment using quotes. For example, pivot,"breakout" will match an order whose comment includes "pivot" (e.g. pivot123), or an order whose comment is the exact text "breakout".

You can also start the list with ! to mean "all comments are permitted except the following". For example:

!pivot,"breakout"

IncludePendingOrders

Determines whether pending orders are sent, or whether the broadcaster only sends messages when trades are filled.

RequireStopLoss

If turned on, the sender will ignore orders until/unless they have a stop-loss. If you open a trade and then add a stop-loss later, the Sender will copy the trade after that delay - but the delay may mean that you need to change the slippage tolerance.

CopyMT5WorkingMarketOrders

MT5 only: copies requests for buy and sell trades as soon as they are sent by MT5 to the broker, without waiting for confirmation of a new filled trade. Can speed up the copying of orders. However, it is then possible for the sender's order to be rejected and for the receiver to have a trade of its own without a matching position on the sender. The receiver's trade will then be closed at the next heartbeat. Slippage comparisons are made against the current/requested price on the sender, which can be different to the price at which the sender's request is later filled by the broker.

4.1.3Sender parameters: lot sizing and pricing

Lot sizing and pricing

(Lot sizing can also be changed using the settings in the receiver EA)

UseFixedLotSize

If not zero, the EA will send this fixed lot size instead of the number of lots actually traded.

LotSizeMultiplier

Ignored if UseFixedLotSize is turned on (i.e. non-zero). Otherwise, modifies the message so that the EA reports this multiple of the actual lot size (e.g. 0.1 to divide lot sizes by 10).

SymbolMultipliers

If not blank, a comma-separated list of multipliers for individual symbols which override the main LotSizeMultiplier setting. The symbol names in this list should exactly match the names on the sender account including any suffix used by the broker. For example: GBPUSD=2,USDCHF=0.5

BroadcastAllOrdersAtMarket

If turned on, the receiver is instructed to buy/sell at the current market price, regardless of the entry price for the sender's position. Equivalent to the receiver turning on the TradeAllOrdersAtMarket setting in the receiving EA.

HideSLandTP

If turned on, the s/l and t/p on trades are not broadcast to the receiver.

AddPipsToSL

Hides the true s/l on each trade by adding this number of pips to it (i.e. moving it further away from the open price). This setting is ignored if HideSLandTP is turned on.

AddPipsToTP

Hides the true t/p on each trade by adding this number of pips to it (i.e. moving it further away from the open price). This setting is ignored if HideSLandTP is turned on.

FixedSLPipsIfNone

If an order has no stop-loss, the system will broadcast the stop-loss as this number of pips from entry.

WaitForProfitPips

Delays transmission of a new order to the receiver until it is in profit by the specified number of pips. The delay can lead to large price differences between sender and receiver, and you will need to change the slippage tolerance.

WaitForSeconds

Delays transmission of a new order for a specified number of seconds. The delay can lead to large price differences between sender and receiver, and you will need to change the slippage tolerance.

4.1.4Sender parameters: broadcast settings

Broadcast settings

RetryAttempts

Number of times to retry if unable to send an order open/close message. (Not used with "heartbeat" messages because they are quickly resent anyway.)

4.1.5Sender parameters: alert and warning settings

Warnings

UserDescription

Controls the description which is displayed in the top-right of the chart, making it easier to distinguish between multiple copies of the EA with different settings. (This setting has no effect on trading behaviour.)

BackgroundColour

Chart background colour which the EA uses. This can be altered to make it easier to distinguish between multiple copies of the EA with different settings.

LabelColour

Colour of the EA's text labels (may need to be changed if you alter the background colour)

SendWarningsByEmail

Any issues which require user attention are always displayed on screen. If this setting is turned on, they are also sent by email (using the details configured in MT4/5's Tools/Options/Email)

WarningEmailSubjectLine

If SendWarningsByEmail is turned on, the subject line to use for any warning emails

4.1.6Sender parameters: advanced settings

Advanced settings

TradeWatchFrequencyMS

MT4: Controls how often the sender checks to see if a new order has been opened, or if an order has been closed. The figure is in milliseconds, and can be set as low as 10. However, values below 25 will typically cause MT4/5 to start using large amounts of processor power without any real improvement in trade placement. The median delay in the sender spotting a new trade will be half the value of this parameter; a value of 50 will typically lead to new trades being detected after 25 milliseconds.

MT5: this setting is largely redundant because, unlike MT4, MT5 notifies EAs when new orders are opened. The MT5 sender EA does not need to do a scan of the account, and the TradeWatchFrequencyMS setting only acts as a backup in case MT5 fails to issue a new-order notification.

SendOrderComments

If turned off, then this prevents the EA from sending the comment for each order to the receiver. In effect, it will turn off the UseOriginalOrderComments parameter in the receiver.

AllowExistingOrders

Allows the EA to send messages about orders which are already open when it starts up

CustomPipSizes

Lets you override the EA's default pip-size calculation for specific symbols (based on the number of digits in the price). For example, to use a pip size of 0.1 on gold and 1.0 on the DAX:

XAUUSD=0.1,GER30=1


4.2.1Receiver parameters: sender channel

Server settings

Channel

The channel name to use for communicating with the sender. There should only be one receiver and one sender on each channel. A receiver can only listen on a single channel; you cannot use a comma-separated list for the receiver's Channel parameter. Channel names must not contain any of the following characters: / \ : * ? " < > |

4.2.2Receiver parameters: local account settings

Local settings

ForexSymbolSuffix

Any suffix used by the broker for forex symbols. For example, if the broker refers to EURUSD as EURUSDcx, then this parameter can be manually set to cx. If left blank, the EA will attempt to detect any suffix which its broker uses. If you want the EA to use no suffix, and not to use auto-detection, then set the parameter to "none" or "(none)"

CustomSymbolMappings

A comma-separated list of symbols which need special mapping between the broadcaster and receiver accounts. For example, GOLD=XAUUSD,CRUDE_OIL=OIL will convert broadcaster trades for GOLD into receiver trades for XAUUSD, and broadcaster trades for CRUDE_OIL into receiver trades for OIL. If the receiving broker uses a suffix such as cx, then this does need to be included in the mapping: e.g. GOLD=XAUUSDcx.

CustomPipSizes

By default the software uses a definition of the pip-size for an instrument which is based on the number of decimal places to which the broker quotes the price. You can override this using a comma-separated list of pip-sizes in the CustomPipSizes field. For example:

XAUUSD=0.10,XAGUSD=0.05

CustomLotMultipliers

Mainly for use on CFDs, where there can be differences in contract size between sender and receiver. Lets you adjust the volumes on specific instruments, before all other lot-size conversions are applied. For example, if the sender's DAX and CAC40 contracts are 100 times smaller than the receiver's contracts, then the following setting will adjust the calculation on the receiver to make the trades 100 times smaller. The symbol names in this list should be the exact symbol names on the receiver, including any suffix:

DAX=0.01,CAC40=0.01

4.2.3Receiver parameters: accept/reject entry signals

Accept/reject entry signals

IgnoreNewEntrySignals

If turned on, the EA ignores all new trade entry signals coming in from the sender - can be used to prevent the EA opening new trades, while continuing to manage existing ones.

PermittedSymbols

If not blank, trades from the sender are ignored unless they are for symbols on this comma-separated list. This must exactly match the broker's names on the receiver account, including upper/lower case such as: EURUSDfx,GBPUSDfx

You can also start the list with ! to mean "all symbols are permitted except the following". For example:

!EURUSDfx,GBPUSDfx

BuySellOnly

If non-zero, restricts the direction in which the copier will place trades. A value of 1 means that the receiver will only place buy orders; a value of 2 means that the receiver will only place sell orders. (Zero means that all orders are accepted.)

IncludeTradingTimes

Ignored if blank. Otherwise, defines a list of times each day during which the receiver is allowed to trade; new order messages outside these times are ignored. See below for the format of this parameter.

day_TradingTimes

Similar to IncludeTradingTimes, but defines separate permitted ranges for each day of the week

IgnoreOrdersSmallerThanLots

Ignored if zero. If non-zero, specifies a minimum order size and the receiver will not trade orders which are smaller than this. This parameter is applied after converting the sender's trade volume using the lot-sizing parameters below. For example, if the sender's lot size is 0.5, and this translates to a receiver lot size of 0.3, then the limit is applied to the size of 0.3.

IgnoreOrdersLargerThanLots

Ignored if zero. If non-zero, specifies a maximum order size and the receiver will not trader orders which are larger than this. This parameter is applied after converting the sender's trade volume using the lot-sizing parameters below. For example, if the sender's lot size is 0.5, and this translates to a receiver lot size of 0.3, then the limit is applied to the size of 0.3.

MinSenderLotSize

Similar to IgnoreOrdersSmallerThanLots, but is applied against the sender's volume before adjusting it using settings such as UseRiskFactor. For example, if the sender's lot size is 0.5, and this translates to a receiver lot size of 0.3, then the limit is applied to the size of 0.5.

MaxSenderLotSize

Similar to IgnoreOrdersLargetThanLots, but is applied against the sender's volume before adjusting it using settings such as UseRiskFactor. For example, if the sender's lot size is 0.5, and this translates to a receiver lot size of 0.3, then the limit is applied to the size of 0.5.

MaxSpreadPips

Blocks new orders if the current spread on the symbol is wider than the specified number of pips. A value of zero disables this check on the spread.

CheckForExistingPosition

Optionally prevents trading if the Receiver has an existing trade or pending order. You can configure the Receiver to ignore signals if there is any open trade or order for the same symbol, or more specifically if there is a trade or order in the same direction as the new signal.

4.2.4Receiver parameters: accept/reject exit signals

Accept/reject entry signals

IgnoreAllExitSignals

If turned on, the EA ignores all exit signals coming in from the sender - can be used if you want to manually control when trades should be closed.

IgnoreExitSignalsForTicketIds

If not blank, a comma-separated list of ticket IDs (on the receiver, not the sender) which should not be managed by the trade copier. Allows some but not all trades to be controlled manually.

4.2.5Receiver parameters: slippage management

Slippage management

TradeAllOrdersAtMarket

If turned on, the receiver always buys/sells at its current market price, regardless of any difference between that and the sender's price. If this setting is turned on, the following three settings become redundant and are ignored.

AllowSlippagePips

Determines how close the receiver's price needs to be to the sender's entry price for a signal to be allowed. For example, if the sender buys GBPUSD at 1.34235, and AllowSlippagePips is set to 2.0, then the receiver will trade the signal provided that its current ask price is not above 1.34255. (This setting is ignored if TradeAllOrdersAtMarket is turned on.)

PlaceLimitOrderIfSlipped

If the receiver's price is beyond the AllowSlippagePips threshold, then this parameter specifies whether the receiver should try to place a limit order - i.e. wait for the price to return to the sender's entry level. (This setting is ignored if TradeAllOrdersAtMarket is turned on.)

LimitOrderExpirationMinutes

Only used if PlaceLimitOrderIfSlipped is turned on. Determines how long the limit order is valid for - i.e. how quickly the price needs to return to the sender's entry level before discarding the signal. Please note that some brokers have minimum expiry periods (e.g. either no expiry, or not less than 15 minutes away). Orders will fail (usually with MT4/5 error #3) if this setting is too low.

ImmediateCloseOnSlippagePips

Closes a new trade immediately if the actual filled price differs from the expected quote price by the specified number of pips. A value of zero disables this check.

MarketOrderSlippageParameter

Only applicable to brokers using instant execution rather than market execution. Specifies the maximum deviation from the current price which the EA is prepared to accept, broadly equivalent to the "max deviation" setting when placing a manual order. Please note that brokers do not necessarily honour this parameter exactly. The default value of 9999 in effect instructs instant-execution brokers to behave like market-execution brokers.

4.2.6Receiver parameters: order management

Order management

OrderRetries

If placing a market order, the number of times the order is retried if the broker requotes.

RequireSenderFillWithinMinutes

If a pending order is filled on the receiver, but remains unfilled on the sender, then the receiver closes it in this number of minutes if it remains unfilled on the sender. This parameter is ignored if less than or equal to zero.

MagicNumber

A magic number to be used by the sender to keep track of its trades. If this is left at zero, the EA automatically picks a unique magic number based on the channel name. Each receiver EA running in a copy of MT4/5 must use a different magic number.

InvertTrades

If turned on, the direction of the broadcaster's trade is inverted, with a buy becoming a sell etc

UseOriginalOrderComments

Tells the receiver to use the original order comment from the sender, instead of its usual behaviour where it tracks the sender ticket number in the order comment. Please note that this setting has disaster-recovery implications.

UseCustomOrderComment

Tells the receiver to use this fixed comment for all orders. This setting overrides any comment on the original order, and also overrides the UseOriginalOrderComments parameter. Please note that this setting has disaster-recovery implications.

PreventPartialExits

Prevents the receiver from doing partial closes; a position is always closed in its entirety if the sender closes any of its position.

IgnorePartialExits

Tells the receiver to ignore partial closes, keeping the original trading volume open without modification. The position is only closed on the receiver when the final tranche is closed on the sender. PreventPartialExits takes precedence; IgnorePartialExits is ignored if PreventPartialExits is turned on.

EntryOffsetPips

If non-zero creates a limit or stop order above/below the sender's entry price, instead of a buy/sell order. A positive value places a stop; a negative value places a limit. For example, a value of -10 means that, when the sender opens a sell position, the receiver will place a sell-limit 10 pips beyond the sender's price

4.2.7Receiver parameters: lot sizing modes

Lot sizing

The following settings are used in order. For example, EquityPerLot will only be used if UseFixedLotSize, UseRiskFactor and UseLotSizeMultiplier are turned off by setting them to zero

UseFixedLotSize

If not zero, the receiver uses this fixed lot size instead of the value specified by the sender. Overrides UseRiskFactor and UseLotSizeMultiplier.

UseRiskFactor

If not zero, tells the receiver to trade a multiple of the sender's lot size based on the receiver's equity versus the sender's equity. For example, if the sender's equity is $1000 and the receiver's equity is $2000, and UseRiskFactor is set to 1, then the receiver will trade double the lot size of the sender. Overrides UseLotSizeMultiplier.

UseLotSizeMultiplier

If not zero, modifies the lot size received from the sender so that the receiver uses this multiple of the broadcast size, e.g. 0.1 to trade one-tenth of the original lot size.

EquityPerLot

If not zero, calculates the lot size based on the receiver's equity, ignoring the sender's lot size. For example, if the receiver's account equity is $4,800, and EquityPerLot is $10,000, then the receiver will trade 0.48 lots.

BalancePerLot

If not zero, calculates the lot size based on the receiver's balance, ignoring the sender's lot size. For example, if the receiver's account balance is $3,200, and BalancePerLot is $10,000, then the receiver will trade 0.32 lots.

CashRiskFixed

If not zero, a maximum cash amount (such as $100) to risk per trade. Requires that sender trades have a stop-loss, or for the FixedSLPips parameter to be set.

CashRiskEquityPercentage

If not zero, a maximum percentage of your equity to risk per trade. Requires that sender trades have a stop-loss, or for the the FixedSLPips parameter to be set.

CashRiskBalancePercentage

If not zero, a maximum percentage of your balance equity to risk per trade. Requires that sender trades have a stop-loss, or for the FixedSLPips parameter to be set.

NotionalDepositVolume

If not zero, instructs the Receiver to trade a fixed amount of the deposit currency. For example:

CalculateRiskFactorFromBalance

If turned on, risk-based lot sizing (UseRiskFactor) will be based on account balance, not account equity

4.2.8Receiver parameters: lot sizing limits

Lot sizing limits

MaxLots

Ignored if UseFixedLotSize is turned on (i.e. non-zero). Caps a variable lot size calculation (e.g. from UseRiskFactor) so that it does not lead to a dangerously large value. If you want to prevent an order being traded, rather than capping its lot size, use IgnoreOrdersLargerThanLots.

MinLots

Ignored if UseFixedLotSize is turned on (i.e. non-zero). Collars a variable lot size calculation (e.g. from UseRiskFactor) so that it does not lead to a value which is too small. If you want to prevent an order being traded, rather than capping its lot size, use IgnoreOrdersSmallerThanLots.

CentAccount

Turn on for accounts where all values are in cents rather than dollars. Equivalent to setting parameters such as UseRiskFactor and LotSizeMultiplier to 0.01 instead of 100.

RoundUpToBrokerMinimum

Ignored if UseFixedLotSize is turned on (i.e. non-zero). Otherwise, determines what to do if the lot size falls below the minimum from the receiver's broker - for example, the broker has a minimum of 0.1 lots; the sender specifies 0.1 lots; and the receiver has UseLotSizeMultiplier set to 0.5; leading to a size of 0.05 lots. If RoundUpToBrokerMinimum is turned on then the receiver will take the trade and use the broker's minimum lot size. If this setting is turned off, then the receiver will ignore the trade.

LotSizingAlwaysRoundDown

If conversion of the sender's lot size leads to a value such as 0.0256, tells the EA always to round down (to 0.02) rather than rounding to the nearest permitted size (0.03).

4.2.9Receiver parameters: stop-loss and take-profit

Please see the notes about when the receiver s/l and t/p are used.

S/L and T/P

FixedSLPips

If non-zero, a fixed number of pips to use for the stop-loss on all trades. If this is turned on, then any stop-loss used by the sender will be ignored. You must turn on FixedSLPips in order to use any of the cash-risk lot-sizing modes such as FixedCashRisk.

FixedTPPips

If non-zero, a fixed number of pips to use for the take-profit on all trades. If this is turned on, then any take-profit used by the sender will be ignored.

MirrorSLandTPChanges

If turned on, the receiver copies the s/l and t/p on each order - but only if FixedSLPips and FixedTPPips are not used. Also controls whether changes to the entry price on pending orders are copied.

MinSLPips

Ignored if FixedSLPips is used. Otherwise, if non-zero, signals are amended so that the stop-loss on trades is never smaller than this number of pips.

MaxSLPips

Ignored if FixedSLPips is used. Otherwise, if non-zero, signals are amended so that the stop-loss on trades is never larger than this number of pips. If the sender does not specify a stop-loss then this number of pips will be used.

MaxCashRiskPerTrade

If non-zero, trades from the sender are ignored if the potential loss is larger than this amount (in the receiver's deposit currency), based on the lot size and stop-loss. Trades will be ignored if the sender does not specify a stop-loss and the receiver does not have MaxSLPips turned on (because loss is potentially unlimited). Please note that this risk is calculated using the tick-value at the time of trade placement, and this can then vary while the trade is active. The risk calculation also does not include any slippage compared to the sender's entry price.

MaxTPPips

If non-zero, signals are amended so that the take-profit on trades is never larger than this number of pips. If the sender does not specify a take-profit then this number of pips will be used.

TrailingStopPips

If non-zero, applies a trailing stop to all orders, overriding and ignoring any s/l specified by the sender. The copier uses a "classic" trailing stop which comes into effect immediately, unlike MT4/5's own trailing stops which only apply once an order is in profit.

4.2.10Receiver parameters: account management

Account management

StopTradingBelowEquity

If turned on (greater than zero), the EA stops taking new signals and attempts to close all its existing orders if the account's equity falls below this cash value. The EA does not close any orders which it is not responsible for - i.e. from other EAs or from manual trading.

StopTradingAtDrawdownPercent

If turned on (less than zero), the EA stops taking new signals and attempts to close all its existing orders if floating P/L falls below the specified percentage of balance. The percentage must be entered as a negative number. For example, if the value were set to -40, then the EA would terminate if e.g. account profit fell below $-800 on a $2000 balance. The EA does not close any orders which it is not responsible for - i.e. from other EAs or from manual trading.

MaxOpenOrders_Total

If non-zero, stops the EA taking new signals if the number of open/pending orders would exceed this value. For example, setting this parameter to 1 will stop the EA trading if there is already any open or pending order. The count includes all orders on the account, from any source, not just those created by the copier.

MaxOpenOrders_FromCopier

As above, but the count only includes orders placed by the receiver EA. There can be any number of orders from other EAs or from manual trading.

MaxTradesPerDay_Total

If non-zero, stops the EA taking new signals if the total activity on the account has already reached this number of orders for the day. Includes all orders from all EAs and from manual trading, and includes open pending orders as well as open and closed trades (but not cancelled pending orders).

CalculateProfitFromOwnOrdersOnly

By default, StopTradingAtDrawdownPercent is calculated using all the open trades on the account. Turning on CalculateProfitFromOwnOrdersOnly changes the calculation so that the Receiver only looks at the drawdown relating to its own trades, ignoring any other activity on the account.

BalanceDateForDrawdown

If specified, the balance calculation for StopTradingAtDrawdownPercent includes all trades, ignoring CalculateProfitFromOwnOrdersOnly, up to but not including the specified date. The calculation of closed and open trades is then from the specified date onwards, only looking at the Copier's own orders if CalculateProfitFromOwnOrdersOnly is turned on. If not specified (the default date of 1/1/1970), then StopTradingAtDrawdownPercent uses the current balance.

MaxTradesPerDay_FromCopier

As above, but the count only includes orders placed by the receiver EA. There can be any number of orders from other EAs or from manual trading.

MaxLosingTradesPerDay_Total

If non-zero, stops the EA taking new signals if the number of losing trades closed (not opened) today has reached the specified threshold. Includes all orders from all EAs and from manual trading. The count only applies to closed trades, not open positions. A limit of 1 does not prevent the Copier from opening 5 concurrent trades which all turn out to be losers.

MaxLosingTradesPerDay_FromCopier

As above, but the count only includes orders placed by the receiver EA. There can be any number of orders from other EAs or from manual trading.

4.2.11Receiver parameters: alerts and notifications

Alerts and notifications

UserDescription

Controls the description which is displayed in the top-right of the chart, making it easier to distinguish between multiple copies of the EA with different settings. (This setting has no effect on trading behaviour.)

BackgroundColour

Chart background colour which the EA uses. This can be altered to make it easier to distinguish between multiple copies of the EA with different settings.

LabelColour

Colour of the EA's text labels (may need to be changed if you alter the background colour)

NewOrders_AlertOnScreen

If turned on, the EA displays an alert on screen about each new trade which it opens

ClosedOrders_AlertByEmail

If turned on, the EA sends an email about each trade which it closes (using the MT4/5 settings in Tools/Options/Email)

RejectedOrders_AlertOnScreen

If turned on, the EA displays a message on screen about each order which it chooses not to trade (e.g. because the lot size is too large/small).

RejectedOrders_AlertOnScreen

If turned on, the EA displays a message on screen about each order which is rejected by the broker.

RejectedOrders_AlertByEmail

If turned on, the EA sends an email about each trade which is rejected by the broker (using the MT4/5 settings in Tools/Options/Email)

Problems_AlertByEmail

Any problems requiring user attention are always displayed on screen. This setting determines whether the messages are also sent by email (using the MT4/5 settings in Tools/Options/Email)

AlertIfHeartbeatMissingSeconds

If non-zero, generates an alert if the EA has not received a heartbeat from the sender for this number of seconds

NoHeartbeat_AlertOnScreen

If AlertIfHeartbeatMissingSeconds is turned on, controls whether alerts about missing heartbeats are displayed on screen

NoHeartbeat_AlertByEmail

If AlertIfHeartbeatMissingSeconds is turned on, controls whether alerts about missing heartbeats are sent by email

Alert text (see below for variables)

OrderOpen_ScreenAlertText

Text to display in relation to NewOrders_AlertOnScreen

OrderOpen_EmailSubjectLine

Subject line for emails sent by NewOrders_AlertByEmail

4.4Trading-time restrictions

The IncludeTradingTimes parameter in the receiver EA lets you control the times of each day when the receiver is allowed to place trades. There are also separate parameters for each day of the week, such as Tuesday_TradingTimes. Any incoming order messages outside these times will be ignored. All times are interpreted as broker time, not local time.

The format of the trading-times parameter is a comma-separated list of permitted times, each of which can be either a single hour (or minute), or a range. Examples are as follows:

2:45 Only allow trading at 2.45am (i.e. between 02:45:00 and 02:45:59)

14 Only allow trading between 2pm and 2.59pm

16-17:30 Only allow trading between 4pm and 5.30pm

7:15-11 Only allow trading between 7.15am and 11.59am (note: 11:59, not 10:59 or 11:00)

19:20-19:25 Only allow trading between 7.20pm and 7.25pm

Any number of these settings can then be combined as a comma-separated list (in any order). Therefore, the above examples could be combined to create a complex trading window as follows:

2:45,14,16-17:30,7:15-11,19:20-19:25

5Diagnosing problems

The sender and receiver EAs create comprehensive records of their activity in MT4/5's Experts log.

We cannot answer support queries without these logs.

The MT4/5 Experts log is different to, and separate from, the MT4/5 Journal.

You can view the copier's records in the Experts tab of the Terminal pane of the MT4/5 software, and you can open the daily log files by right-clicking over the Experts log and choosing "Open" from MT4/5's pop-up menu.

Please note:

We need the log files in order to answer support queries. Please do not send us screenshots unless we specifically ask you to. We generally cannot answer support questions from screenshots.

Please make sure that you send us the Experts log, not the Journal (unless we ask you to).

Most questions about the copier's behaviour are simply explained by its records in the Experts log. Please check the logs before sending them to us. The copier is free software, and we will give very low priority to support queries from users who do not appear to have checked the logs before sending them to us.

5.1No "heartbeat" received

The receiver EA should start receiving heartbeat messages from the sender shortly after starting up, and display the last-heartbeat time on its chart. If no heartbeats are being received, or the copier is not loading at all, then please check the following:

The sender and receiver EAs are both using the same channel name.

The sending and receiving copies of MT4/5 are both connected to their brokers.

There is no record in the logs that the EAs have been forced to terminate for some reason. In particular, please check that the "Allow DLL imports" setting is turned on, and that there is no record in the logs that the software has terminated because it cannot load its DLL.

5.2Heartbeats are received but trades are not copied

The MT4/5 Experts log on the sender and receiver will confirm why a trade has not been copied. If the receiver is successfully getting heartbeats from the sender, and updating its display of the last-heartbeat time, then there are only two reasons why a trade will not be copied:

The sender is not configured to broadcast the trade. The sender logs will confirm whether a trade was sent to the receiver and, if not, why not.

The receiver EA or the receiver's broker rejected the sender's signal. The receiver logs will confirm receipt of the message from the sender, and show any rejection and the reason for that rejection.

Common reasons why trades cannot be copied are as follows. All of these will be listed and described in the logs.

The software cannot translate between the symbol names used on the sender account and the symbol names on the receiver account. You may need to adjust the receiver's ForexSymbolSuffix setting or, particularly for non-fx markets, you may need to add a CustomSymbolMapping.

The software's default lot sizing is not to trade exactly the same sizes on the receiver as on the sender. The default conversion may mean that orders are too small to trade on the receiver account. You either need to turn on the RoundUpToBrokerMinimum parameter in the receiver EA, or you need to choose a different lot-sizing mode. Please note that both of these options will mean that the receiver is taking more risk per order than the sender account.

The main "AutoTrading" button in MT4/5 is turned off, or the "Allow live trading" setting is not turned on for the receiver EA. Please note that the option in MT4/5's Tools / Options / Expert Advisors does not affect any EAs which are currently running; the setting in Tools / Options is the default for when you next add an EA to a chart. ("Allow live trading" in MT4/5 means "allow trading by automated systems", not "allow trading on a live account as opposed to a demo account".)

If the price difference between sender and receiver is larger than AllowSlippagePips, the copier's default behaviour is to open a pending order at the sender's original entry price. But your broker may have a minimum distance between pending orders and the current market price. It is possible for the difference to be larger than AllowSlippagePips but smaller than the broker's minimum distance, making it impossible to open a trade or pending order unless you increase AllowSlippagePips.

5.3Trading error codes from the MT4/5 server

The copier will log any rejections by the broker's MT4/5 server. All common errors will be accompanied by a description (such as "requote" for error #138 in MT4).

For more information on error codes from MT4/5, please see the MT4/5 documentation:

MT4: https://docs.mql4.com/constants/errorswarnings/enum_trade_return_codes

MT5: https://www.mql5.com/en/docs/constants/errorswarnings/enum_trade_return_codes

A few extra notes on error messages which are famously obscure in the MT4/5 documentation:

Automated trading disabled (MT4 error #4112, MT5 error #10026): usually means that your account has multiple versions of each symbol, such as EURUSD and EURUSD+, and you are trying to trade the wrong one. Automated trading is not usually disabled; more commonly means that the symbol version you are trying to trade is disabled by the broker and only included in the account for internal purposes. You typically need to use the ForexSymbolSuffix setting or a CustomSymbolMapping to tell the copier to trade a different version of the symbol.

MT4 error #130: this can have two separate causes. Either a stop-loss or take-profit is closer to an order's entry price than the broker allows, or the entry price on a pending order is closer to the current market price than the broker allows.

MT4 error #136: typically indicates an unexpected problem on the broker's server. For example, the broker has lost its connection to external liquidity or an external price feed, and is rejecting client trades because it cannot currently process them.

5.4Trades are opened multiple times

If the same trade is copied more than once on the receiver account then there are two possible explanations: you are running more than one instance of the receiver copy of MT4/5; or the connection with the broker is timing out and the broker is placing trades despite returning an error message.

5.4.1Multiple copies of the same receiver

Please use the Windows Task Manager to check that you only have the expected number of running copies of MT4/5 (terminal.exe / terminal64.exe), making sure to use the "Show processes from all users" option.

On a VPS in particular, it is quite easy to open multiple remote-desktop sessions by accident, and have the same copy of MT4/5 running in more than one session at once.

5.4.2Timeout errors from the broker

If the broker's server returns a timeout error, then the receiver will retry the order (unless OrderRetries is set to zero). Despite returning an error, the broker may in fact have accepted the order, and the retry may then create a duplicate.

If you receive timeout errors from the broker server, you should contact your broker. It indicates either a problem with your broker's server, or a problem with your internet connection to the broker.

5.5Trades are instantly closed on the receiver

The main reason why trades are instantly closed on the receiver is that there is more than one EA sending messages on the specified "Channel".

Please check the following:

Check the MT4/5 Experts log. The reason for all actions by the copier will be confirmed in these logs.

Check that you are only running one copy of the sender EA or, if there are multiple sender EAs, check that each one is using a different channel parameter.

Use the Windows Task Manager to check that you only have the expected number of running copies of MT4/5 (terminal.exe / terminal64.exe), making sure to use the "Show processes from all users" option.

6MT5 netting accounts

This section only applies to MT5, not MT4, and it only applies to netting accounts in MT5 (where there is a single position per symbol, rather than hedging accounts which have separate tickets for each buy and sell).

The copier can be used on MT5 netting accounts, but there are additional considerations which you need to bear in mind. To use the copier on a netting account, you need to turn on the AllowMT5NettingAccount setting in the Advanced section of the EA's options, to indicate that you have read this part of the user guide.

6.1Receiver netting account

On an MT5 netting account, the Receiver will maintain a list of "virtual" positions. For example:

Sender is a hedging account, and opens separate tickets for a buy and then a sell in EUR/USD. Sender has no net position in EUR/USD, but has two open tickets because it is a hedging account.

The MT5 netting Receiver will open a EUR/USD position (corresponding to the sender's buy) and then close it (corresponding to the sender's sell)

But the MT5 netting Receiver is still tracking the "virtual" buy and sell positions on the sender

If the sender closes its sell ticket, the netting Receiver will re-open its buy position in EUR/USD - matching the net position (the buy ticket) which the sender now has

There are three special things you need to bear in mind about using the Receiver on an MT5 netting account:

If you want to close the Receiver's positions, you must do so using the list which it displays in the top-right of its chart, and the Close button next to each virtual ticket. You cannot close a virtual position in the Receiver just by closing the actual position on your account. The Receiver cannot know that a trading action by you - or another EA etc - is meant to be a close of the Receiver's position rather than an independent trading action.

For example: Sender opens a buy ticket. Receiver opens a corresponding buy position. You manually close the buy position on your account without using the Close button on the Receiver's chart. The Receiver still regards its virtual position as open. Sender closes its buy ticket. Receiver will place a new sell order, opening a new short position, matching the activity on the sender.

The Receiver will not copy any s/l or t/p from the sender (which are anyway only a safeguard). The sender may have multiple tickets with a different stop-loss and take-profit whereas the netting account can only have a single s/l and t/p. Trades will still be closed when they are closed on the sender (or disappear from the sender's heartbeat).

The Receiver has to track its virtual tickets using a file on disk (in MQL5\Files). If you move the Receiver to another computer, you need to transfer this file, or else the Receiver will lose its memory of the virtual tickets which it has open.

6.2Sender netting account

On an MT5 netting account, the Sender will maintain a list of "virtual" tickets corresponding to your current net position on your account. For example: you buy 0.20 lots EUR/USD and then buy a further 0.10 lots. The MT5 account will show a single position of 0.30 lots. But the Sender will broadcast separate virtual tickets of 0.20 lots and 0.10 lots, allowing hedging accounts (in MT4 or MT5) to match the Sender's activity.

The Sender will then process closes on a FIFO basis. Continuing the same example, let's say that you sell 0.25 lots, leaving you with a net position in MT5 of 0.05 lots. The Sender will treat this as a complete close of the 0.20 virtual ticket, and a partial close of the 0.10 ticket.

There are two special things you need to bear in mind about using the Sender on an MT5 netting account:

You cannot use IncludePendingOrders on a netting account. You can only send changes to your open positions.

The Sender has to track its virtual tickets using a file on disk (in MQL5\Files). If you move the Sender to another computer, you need to transfer this file, or else the Sender will lose its memory of the virtual tickets which it has open.

7Controlling the copier using MQL code

You can make your own modifications to the copier using MQL code libraries in MT4/5.

Before describing the libraries, there are two important notes about re-installing the copier if you use these external filters:

If you re-run the copier's installer program, this will overwrite any changes which you have made to the custom code libraries described below. If you make changes, you should keep copies of your modified files, and re-install them into MT4/5 after you re-run the copier's setup program.

In future versions of the copier, there may be additions to the functions/hooks in the external filter libraries. When a new version of the copier is released, you may need to update your modified code with new functions which the copier expects to find in the external MQL library.

The copier has MQL code libraries called CopierSenderFilter and CopierReceiverFilter. These are used by the copier if you turn on the UseExternalFilters setting in the Advanced section of the sender and receiver options. You can modify and recompile these libraries to create your own rules for the following:

Prevent the sender copying specific trades

Prevent the receiver copying specific signals from the sender

Change how the receiver copies a trade from the sender - override the lot-sizing, swap the trade direction, change the s/l or t/p, or even change one symbol to another

Prevent trade closes in the receiver

For information on how the filters work, simply open the .mq4/.mq5 files in MT4/5's MQL\Libraries directory. You can add your own rules to these files, recompile the .ex4/.ex5 library, turn on UseExternalFilters, and then reload the copier. Please remember to take a backup of your modified files - as described above.

8MT4 worker EA (optional)

This section is only applicable to MT4, not to MT5. Trade placement in MT5 is asynchronous. The MT5 copier does not need (and does not have) the optional worker EA described here.

An EA in MT4 cannot do anything else while it is waiting for the broker to accept/reject a trading instruction. Therefore, if two (or more) signals arrive from the sender simultaneously, the MT4 receiver cannot start working on the second one until the broker has accepted/rejected the first one. If trade placement by the broker is slow (including a slow internet connection to the broker), then this can lead to quite large delays in trade copying.

You can improve the speed of copying in MT4 using the optional Receiver-Worker EA. You use this as follows:

Run the Receiver EA on one chart

Open at least two further charts, and run the Receiver-Worker EA on each of them

The main Receiver EA will automatically detect the workers, and use the workers to place trades for it

This allows the Receiver to handle more than one trading instruction at once

There is no point using the Receiver-Worker unless you run at least 2 copies of it. A single copy will still only allow a single trading action by MT4 at once, and will be fractionally slower than not using a worker at all because of the time taken for the Receiver to communicate with the worker rather than the Receiver EA just placing the trade itself.

However, there is also no point running more than 8 copies of the Receiver-Worker. MT4 has a limit that only 8 EAs can trade simultaneously.

The following screenshot shows an example of the Receiver EA running alongside three workers:
