This is the most reliable way to obtain the source code if you have lost it or need modifications. Use the iCustom Function:
When a developer completes an MQ4 file, they compile it. MetaEditor translates the human-readable code into a binary format that the MetaTrader 4 platform executes. This file cannot be opened directly in a text editor. ex4 to mq4 decompiler 40432 updated
; it typically produces broken code, random variable names, or illogical logic structures. System Requirements : The tool generally requires Microsoft .NET Framework 2.0 or higher to run on Windows. Risks and Safety Warnings
: Even when successful, decompiled code often loses original variable names, comments, and formatting, making it difficult to read. Use the iCustom Function: When a developer completes

Drag and drop your .ex4 file directly onto the decompiler window. ; it typically produces broken code, random variable
It provides raw assembly or low-level bytecode rather than functional MQ4 text. The resulting code lacks original variable names, comments, and structure, making it virtually unreadable.
If a developer loses their original files due to a hardware failure.
