Trade Copier Program for Metatrader 5

Overview

• Creating a trade copier program for Metatrader 5
• The program will operate between two Metatrader terminals with different accounts.
• One terminal acts as "master" and the other as "slave".
• The master terminal will send commands (open/close trades) to the slave terminal.

Development Environment Setup

1. Open Metacodes Language Editor.
2. Create a new Expert Advisor program (e.g., trade copier youtube).
3. Delete comments and unneeded functions (like onTick).

File Sharing Mechanism

• Use a shared folder for file storage accessible by both terminals.
• Define file name for trade information (e.g., mqlinfo string.bin).
• Include necessary libraries:
  • trail.mqh for position handling.
  • arraylong.mqh for ticket storage.

Mode Enumeration

• Define an enumeration for operating modes:
  • mode master
  • mode slave
• Set default mode to slave.

Timer Setup

• Use event set timer for a recurring event (e.g., every 500 milliseconds).
• Remember to kill the timer in onDeinit.

Master Terminal Logic

1. Opening/Creating File: Use file open to write to the shared file.
2. Position Handling:
   • If no open positions, delete the file.
   • Loop through all open positions and write their properties (ticket, symbol, volume, type, SL, TP) to the file.
3. Closing the File after processing.

Slave Terminal Logic

1. File Handling: Open the shared file in read mode.
2. Reading Positions:
   • Loop until the end of the file, read trades and their properties.
3. Position Comparison:
   • Loop through existing slave positions, check if they match master positions using position ticket stored as a comment.
   • If not found, open the position on the slave terminal.
4. Updating Positions: Check and update SL and TP if they differ from those in the master.
5. Closing Unmatched Positions: Loop through slave positions, close those not found in the master.

Compilation and Testing

• Compile the code in the MetaEditor.
• Drag and drop the newly created Expert Advisor onto a chart in both terminals.
• Ensure the master is set to mode master and the slave to mode slave.

Performance Demonstration

• Open positions on the master terminal to see them copied to the slave.
• Changes in SL and TP on the master are reflected on the slave.
• Note: Opening a position on the slave that isn't on the master will be closed by the program.

Code Summary

• The program contains about 99 lines of code.
• Easily modifiable for additional features like adjusting lot sizes, using FTP servers, etc.
