If you have an EX4 file that you absolutely need in MQL4 format, follow this workflow:
Before attempting a conversion, it helps to understand why these files are structured differently.
Your time and money are far better spent on legitimate alternatives: recreating the logic behaviorally, hiring a developer, using open-source options, or accepting the EX4 as-is. how to convert ex4 file to mql4
Traders often look to decompile an EX4 file for a few common reasons:
Would you like help understanding how to manually recreate an EA’s logic from its behavior instead? If you have an EX4 file that you

If you legitimately bought an EA and need the source code for personal modifications, contact the original developer. Many developers are willing to sell the MQL4 version or provide custom modifications for a reasonable fee. Best Practices to Avoid Needing Decompilation
