If the "decompiler" itself is open-source (e.g., written in Python), read the code to ensure it isn't sending data to an external server.
Legally, modifying or reverse-engineering an EX4 file that you do not own violates the MetaTrader End User License Agreement (EULA) and copyright law. If you need to replicate a specific indicator functionality, look for open-source mathematical equivalents on GitHub rather than trying to crack an existing binary file.

: Users have attempted to load EX4 files into Ghidra , but it does not natively detect the MQL4 language. Successful use requires manually specifying processor descriptions and byte-code instructions.
This guide breaks down the technical reality of EX4 files, why automated decompilers fail, and how to safely solve your coding problem. What Are EX4 and MQ4 Files? Guide you to on the MQL5 Community to hire a programmer
True, flawless decompilation of modern EX4 files back into readable MQ4 code is virtually impossible without extreme manual reverse-engineering effort. What You Actually Find on GitHub
: Most of these tools have a very simple interface. You typically select the input .ex4 file and click a button like "Decompile" or "Convert".
Even if a highly advanced decompiler extracts the logic, you will receive a chaotic mass of code filled with variables named g_var_12 , ind_buffer_0 , and l_count_4 . Reconstructing the original logic requires expert assembly-level reverse engineering. MetaQuotes Encryption
Searching GitHub for an "EX4 to MQ4 decompiler" yields several types of repositories. Understanding what they actually contain is vital before downloading anything. 1. Proof of Concept (PoC) Code
