Since the 2014 MetaTrader update (Build 600+), simple decompilers largely stopped working. Most successful "decompilation" is now done by:
In 2021, several repositories gained popularity. Letโs examine them:
Finding a working EX4 to MQ4 decompiler on GitHub in 2021 was a common goal for traders who lost their source code or wanted to study Expert Advisors (EAs). However, the reality of these tools is often far from the "one-click" solution promised in forum posts and repository descriptions. The Technical Barrier: Build 600+
Advanced users can open the EX4 in a hex editor or use a disassembler like (not a decompiler). This shows the assembly-like logic, which you can manually translate to MQ4. This is time-consuming but legal for educational use in some jurisdictions.
: Always run unknown recovery tools in a Virtual Machine or "Sandbox." ๐ Common Approaches for Code Recovery 1. MQL4 Recovery Services
EX4 and MQ4 are file formats used by MetaTrader, a popular trading platform for foreign exchange (Forex) and other financial markets. EX4 files contain compiled expert advisors, indicators, and scripts written in MQL, a programming language used for developing trading strategies. However, due to the compiled nature of EX4 files, it can be challenging to reverse-engineer or modify them. Decompilers aim to translate EX4 files back into their original MQ4 source code. This paper reviews the state of EX4 to MQ4 decompilers on GitHub in 2021, highlighting popular repositories, their features, and limitations.
However, I provided a general overview of what such a paper could look like. For actual implementation and more detailed results - more specific data would be required.
