I created a trade copy tool, but a good free one was released by FX Blue and others.

I reworked it to my specifications from the published source code.
The source code is attached. Feel free to use it.

I translated it from Japanese to English, but I have not translated it from English to Japanese and checked it for proper text.I'm sorry.

• Overview
  　　Copies trades from one account to another.
• Operating Environment
  　　Runs on MT5.
• Functional Overview
  　　The source EA and destination EA are linked using the "Pairing ID" parameter.
  　　Trades from a single source account can be copied to multiple destination accounts.
  　　The source EA allows multiple Magic Numbers to be specified for copying.
• Operating Conditions / Limitations
  　　Only supported within the same PC.
  　　Only supported between MT5 terminals.
  　　Only Hedging mode is supported. Netting mode is not supported.
  　　Only market orders are supported. Pending orders are not supported.
  　　Multiple instances using the same Pairing ID cannot run within a single account.
• Detailed Specifications
  　　Copy Operations
  　　　　New Orders
  　　　　　　Copies market orders, including SL and TP.
  
  　　　　Modified Orders
  　　　　　　Updates SL and TP.
  
  　　　　Closed Orders
  　　　　　　Any copied trade that exists on the destination account but no longer exists on the source account will be closed.
  
  　　　　Magic Numbers
  　　　　　　Only the Magic Numbers specified in the parameters are copied.
  　　　　　　Multiple Magic Numbers can be configured.
  
  　　　　Ignore Delayed Trade Orders
  　　　　　　If a delay occurs between the source EA and the destination EA, you can choose whether delayed trades should be copied.
  　　　　　　The maximum acceptable delay is specified in milliseconds (ms).
  
  　　　　Ignore Past Trade Orders
  　　　　　　If the PC or this system is restarted for any reason, you can choose whether historical trades should be copied.
  　　　　　　The historical look-back period is specified in seconds (s).
  
  　　Destination EA Behaviour
  　　　　Magic Number
  　　　　　　The destination EA operates using the configured Magic Number.
  
  　　　　User Intervention
  　　　　　　If a copied position is manually closed on the destination account,
  　　　　　　it will remain closed and will not be copied again.
  　　　　　　If a copied position is manually modified on the destination account,
  　　　　　　its settings will be restored to match the source account.
  　　　　　　If a new position is opened manually on the destination account,
  　　　　　　it will be closed because it does not exist on the source account. (This does not apply if it uses a different Magic Number.)
  
  　　　　Lot Size
  　　　　　　The default lot size is calculated according to the balance ratio between the source and destination accounts.
  　　　　　　The result is then adjusted using the configured lot conversion ratio parameter.
  
  　　Behaviour During Abnormal Conditions
  　　(or until both the source and destination EAs have fully started)
  　　　　Source EA Stopped
  　　　　　　Real-time copying (new orders, modifications, and closures) cannot be performed while the source EA is stopped.
  
  　　　　Source EA Restarted
  　　　　　　Historical new orders are copied according to the "Ignore past trade orders" parameter.
  　　　　　　Historical order modifications are copied.
  　　　　　　Historical order closures are copied.
  
  　　　　Destination EA Stopped
  　　　　　　Real-time copying (new orders, modifications, and closures) cannot be performed while the destination EA is stopped.
  
  　　　　Destination EA Restarted
  　　　　　　Historical new orders are copied according to the "Ignore past trade orders" parameter.
  　　　　　　Historical order modifications are copied.
  　　　　　　Historical order closures are copied.
  
  　　　　PC or MT5 Experiences Performance Delays
  　　　　　　Delayed new orders are copied according to the "Ignore delayed trade orders" parameter.
  　　　　　　Delayed order modifications are copied.
  　　　　　　Delayed order closures are copied.
• Startup Procedure
  　　There is no required startup order. The source EA and destination EA may be started in any order.
• How It Works
  　　The source EA and destination EA exchange data via the MT5 "Common\Files" directory.
  　　Since MT4 and MT5 use the same file format and data specification, they are theoretically compatible with each other.
  　　However, this has not yet been verified.

While I was at it, I also confirmed that copying between MT4 and MT5 works.
MT4 needed a fix.

• Pairing ID
  Set the same "Pairing ID" for the Expert Advisors that will copy positions (Trade_copy_src and Trade_copy_des).
  The "Pairing ID" must match between the source (Trade_copy_src) and the destination (Trade_copy_des).
  If you are running multiple instances of this EA, be sure to assign a unique "Pairing ID" to each pair.
• Synchronisation Interval (ms)
  Specify, in milliseconds (ms), how often the source EA retrieves the current position status and sends it to the destination EA.
• Operating EA after MT4 start-up
  Specify whether the EA (Trade_copy_src) should start operating automatically when the MT4 terminal is launched or when the EA is attached to a chart.
• MagicNumbers (1,2 ...) If empty, all
  Specify the Magic Number(s) that Trade_copy_src will copy.
  Multiple Magic Numbers can be specified by separating them with commas.
  If left blank, all Magic Numbers will be copied.

• Pairing ID
  Set the same "Pairing ID" for the Expert Advisors that will copy positions (Trade_copy_src and Trade_copy_des).
  The "Pairing ID" must match between the source (Trade_copy_src) and the destination (Trade_copy_des).
  If you are running multiple instances of this EA, be sure to assign a unique "Pairing ID" to each pair.
• Synchronisation Interval (ms)
  Specify, in milliseconds (ms), how often the destination EA receives the position status from the source EA and places the corresponding orders.
• Ignore delayed trade orders (ms)
  Specify whether trades should be copied when a delay occurs between the source and destination EAs.
  Set the maximum acceptable delay in milliseconds (ms).
• Ignore past trade orders (s)
  Specify whether trades that occurred in the past should be copied if the PC or this system is restarted for any reason.
  Set how far back, in seconds (s), the system should look when considering past trades.
• Trade Copy System MagicNumber
  Specify the Magic Number to be assigned to orders placed on the destination terminal.
• Operating EA after MT4 start-up
  Specify whether the EA should start operating automatically when the MT4 terminal is launched or when the EA is attached to a chart.
• Symbol Convert (src=des, src=des ...)
  Use this parameter if the symbol names differ between the source and destination terminals.
  Multiple symbol mappings can be specified by separating them with commas.
  Example:
  If the source symbol is "XAUUSD" and the destination symbol is "GOLD", specify:
  XAUUSD=GOLD
• Remove Suffix of Copy Source
  Use this parameter if the source and destination symbols have different suffixes.
  Specify the suffix appended to the source symbol that should be removed before matching.
• Add Suffix of Copy Destination
  Use this parameter if the source and destination symbols have different suffixes.
  Specify the suffix to be appended to the destination symbol when placing copied trades.
• Conversion Ratio
  By default, the position size is calculated automatically according to the balance ratio between the source and destination accounts.
  If you need to increase or decrease the calculated position size further, use this parameter.
  If the method used to calculate position sizes differs between the source and destination environments, use this parameter to compensate for the difference and ensure the copied position size is calculated correctly.
  However, this tool cannot be used if the position size calculation method is consistent for some symbols but different for others.
  
  　　　　　　Example 1
  　　　　　　　　Source account balance: 1000
  　　　　　　　　Destination account balance: 100
  　　　　　　　　Source position size: 10 lots
  　　　　　　　　To calculate the destination position size based solely on the account balance ratio:
  　　　　　　　　Conversion Ratio = 1.0
  　　　　　　　　Destination position size:1 lot
  
  　　　　　　Example 2
  　　　　　　　　Source account balance: 1000
  　　　　　　　　Destination account balance: 100
  　　　　　　　　Source position size: 10 lots
  　　　　　　　　To calculate the destination position size based on the balance ratio and then reduce it by half:
  　　　　　　　　Conversion Ratio = 0.5
  　　　　　　　　Destination position size:0.5 lots
  
  　　　　　　Example 3
  　　　　　　　　Source account balance: 1000
  　　　　　　　　Destination account balance: 1000
  　　　　　　　　Source position size: 10 lots
  　　　　　　　　If, due to differences in the lot size calculation method, the destination position size must be ten times larger:
  　　　　　　　　Conversion Ratio = 10.0
  　　　　　　　　Destination position size:100 lots
  
  　　　　　　Calculation Formula
  　　　　　　　　(A) = (a) × (r) × (B) / (b)
  
  　　　　　　　　(r) = Conversion Ratio
  　　　　　　　　(A) = Destination lot size
  　　　　　　　　(a) = Source lot size
  　　　　　　　　(B) = Destination account balance
  　　　　　　　　(b) = Source account balance

• "NOT OPERATING"
  When "NOT OPERATING" is displayed, the EA does not monitor position status and does not copy any positions.
  Click the button to switch the status to "OPERATING".
• "OPERATING"
  When "OPERATING" is displayed, the EA monitors position status and copies positions accordingly.
  Click the button to switch the status to "NOT OPERATING".

Thanks for the trade copier and the documentation. I made trades on MT4, copied them to MT5 and it's working very well. I checked all the entry and exit times and they are mostly the same to the second but the exit prices sometimes differ by a fraction of a pip and that is expected. Also, all the SL and TP prices are exactly the same, which means that the SL values were modified successfully since on the MT4 sending side, a trailing stop moved the SL values. However, I got some errors that I pasted below:

2026.07.21 06:42:47.335 Trade_copy_des (AUDCAD,M5) CTrade::OrderSend: modify position #5109484 GBPUSD (sl: 0.00000, tp: 0.00000) [no changes]

2026.07.21 09:36:35.346 Trade_copy_des (AUDCAD,M5) Alert: error : modifying position code=4756

What do you think may be the cause of those errors and what values can I change to avoid those type of errors in the future? Thanks.
