Even when decompilation succeeds, the result is typically "somewhat readable as 'code'" but is "not very human readable, in order for its functionality to be understood and changes to be made."
The , particularly version 4.0.432.16, is a specialized tool designed to reverse this compilation process. It attempts to reconstruct human-readable MQL4 source code from the compiled EX4 binary. While such tools exist on the fringes of the MT4 ecosystem, they occupy a controversial space—simultaneously serving legitimate needs while carrying significant legal and ethical risks.
Where the decompiled MQ4 will be saved.
For example, a function call that was clearly separated in the original source might be inlined directly into the calling function. This means a decompiler might produce a flat, monolithic block of code that is functionally correct but lacks the original modular structure, making it difficult to maintain or reuse.

The EX4 to MQ4 decompiler 4.0.432.16 and similar tools are typically distributed through third-party websites, coding forums, and repositories. Some Chinese platforms, such as GitCode and AtomGit, host repositories containing decompilation utilities explicitly for research purposes.
