The library is designed for universal application, allowing integration with virtually any EA via the #include compiler directive.
To integrate the library into your EA, follow these steps:
1. Include the library using the compiler directive before function declarations.
2. Declare the necessary global variables.
3. Declare the external parameters for the trailing stop functionality.
4. Add a specific line of code at the end of the start() function.
5. Place the library file (a-simpletrailing.mqh) into the terminal's .../experts/include/ directory.
Once integrated, your EA will gain access to the following external parameters:
The trailingpositions() function supports the following parameters:
- symbol name: Specify a particular symbol or use "" for the current symbol.
- operation: Filter by position type (-1 for any position, 0 for buy, 1 for sell).
- magicnumber: Filter by magic number (-1 for any magic number).
These parameters enable you to refine the scope of the trailing stop operation. For instance, you can apply it only to EURUSD trades:
Or exclusively to GBP sell positions:
If your EA utilizes a magic number, ensure it is passed to the trailing stop maintenance function:
