If you purchased the software, most developers will provide support or updates if you've lost your files.
Some services don't actually "decompile" into perfect MQ4 code; instead, they provide a "broken" version that requires extensive manual fixing to be functional. The Risks of Using Decompilers ex4tomq4 v4 decompiler version 405 full exclusive
Downloading "exclusive" versions of such software from unverified sources is the fastest way to compromise your trading terminal and personal data.
You will often see "Version 4.0.5" or "V4" advertised on various forums and file-sharing sites. Historically, older versions of MT4 (prior to Build 600) were relatively easy to decompile. However, MetaQuotes (the developer of MT4) implemented a massive security overhaul years ago. Modern EX4 files are heavily encrypted and obfuscated
The MQL5/MQL4 codebase has thousands of free, open-source indicators that likely perform the same functions as the compiled one you are trying to reverse-engineer. Conclusion
Modern decompilation often fails to recover variable names. You might get the logic, but it will be filled with generic names like var1 , var2 , and sub_routine_A , making it nearly impossible to debug or optimize. Better Alternatives However, MetaQuotes (the developer of MT4) implemented a
They only work on EX4 files compiled on very old versions of MT4 (pre-2014).
Decompiling software often violates the End User License Agreement (EULA) of the original developer. If you are trying to "crack" a paid EA, you are likely infringing on intellectual property rights.
