Hire a professional MQL developer to "reverse-engineer" the logic. Instead of decompiling, they watch the EA's behavior and rewrite the code from scratch.

They might explain the logic of bytecode but don't provide a functional tool for end-users. Why Decompilation is Harder Today

Before you download a tool from a random GitHub repository, consider these risks:

It is important to note that by GitHub or MetaQuotes. In fact, most repositories claiming to offer one-click decompilation for modern EX4 files are often: Outdated: They only work on MT4 builds from a decade ago.

About Me

I am a game developer and a passionate pianist. When I first got into AR I was immediately hooked and couldn't think of a better use-case than piano learning. Combining my two passions this felt like a perfect match and I went on to spend the next few years developing prototypes for different hardware and researching digital music education.
