Files are now compressed and encrypted with proprietary algorithms. Standard decompilers cannot reverse these; they often produce broken code, placeholder logic, or simply fail to open the file.
If you are struggling with a specific Forex tool, finding the original developer or a competent MQL4 programmer is a more reliable solution than relying on outdated decompilation tools.
Some developers offer custom MQL4 auditing services to reproduce the functionality of an .ex4 file without direct decompilation. Legal and Ethical Considerations
