MetaQuotes and many developers consider decompilation a violation of copyright laws, and the process is often deemed illegal for commercial use in many jurisdictions.
Rather than a perfect MQ4 file, these tools provide raw analysis and function identification to help developers understand the logic of an expert advisor (EA) or indicator. Risks and Security Warnings ex4 to mq4 decompiler github 2021
Decompilation is the reverse engineering process. It attempts to reconstruct the original text file from the binary bytecode. The Myth of the "GitHub 2021" Decompiler
