Finding a GitHub repository that can fully decompile modern MetaTrader 4 (MT4) .ex4 files into readable .mq4 source code is practically impossible due to technical and legal barriers. Most current GitHub projects are either wrappers for older, discontinued software or partial analysis tools rather than full decompilers. Status of GitHub Repositories
Decompilation enables widespread theft. The “primary reason why decompiled files exist is because of scamming and theft. People who do not know how to code will take an .EX4 file that was made by a coder and will decompile the file, re‑name it to something different … then market it as their own.” This practice directly harms developers who have invested hundreds or thousands of hours creating unique strategies.
The executable might mimic a terminal interface but silently installs a backdoor.
Decompiling involves reversing the compilation process to transform ex4 files back into a higher-level, human-readable form, ideally close to the original mq4 code. However, decompilation is not a straightforward process and might not always yield perfectly readable or compilable code due to the loss of high-level variable names, function names, and comments during compilation.
