To turn the machine code back into readable code.
Modern MetaTrader 4 builds, particularly those post-build 600, use stronger compilation techniques. Decompiling these files often produces unusable code or fails entirely.
The EX4 to MQ4 Decompiler 5.0.1 EXE is a popular and widely-used decompiler tool specifically designed for MetaTrader 4. This software is capable of decompiling .ex4 files, converting them back into their original MQL4 source code. ex4 to mq4 decompiler50 1 exe top
A completely overhauled compiler matching the structure of MQL5. Advanced code encryption, obfuscation, and compression. Strict data typing and native security protocols.

). While older versions (like 4.0.432) from developers such as purebeam.biz were once popular for restoring lost source code, 5.0.1 is frequently sought for newer, tougher, and highly protected indicators and Expert Advisors (EAs). Here is a solid look at the reality of this tool. The "Solid" Story: Reality vs. Promise

– Some argue that decompiling EX4 files for educational purposes (e.g., studying how certain algorithmic patterns are implemented) could fall under fair use in certain jurisdictions, provided the files are not protected by copyright or are used strictly for non‑commercial learning. However, this position remains legally ambiguous and is not endorsed by MetaQuotes or the broader MT4 community.
The compiled file. It is machine-readable by the MT4 platform but not editable by humans.
Decompiled code requires extensive manual repair to become usable. Variables are renamed arbitrarily, control flow structures may be distorted, and complex logic involving external DLL calls or advanced MQL4 features may not decompile correctly at all. Some tools claim to decompile only partially, leaving critical functions missing or incorrectly reconstructed.
Using a decompiler to reverse‑engineer a commercial EA or indicator could expose the user to legal action from the copyright holder. While some online forum participants debate whether such actions could lead to criminal prosecution, the civil liability is clear. Developers who have had their work stolen have taken legal measures against violators. The risk of being sued for copyright infringement should not be dismissed lightly.
