Create a thread explaining that you lost your original source code. Upload your EX4 file and politely ask if anyone can help you extract the MQ4 code. Crucial Security and Legal Warnings
Today, the landscape of conversion has shifted. While free software is no longer effective, a market for paid decompilation services has emerged. While this contradicts the premise of finding "free work," it is the reality of the current technical environment. These services use proprietary algorithms to crack the code, but the results are inconsistent. Often, the recovered code is cluttered with machine-generated variable names (e.g., var_1 , var_2 ) and lacks the comments and structure of the original source, making it difficult to read and modify.
Most free tools claiming to convert EX4 to MQ4 do one of three things:
If you need the functionality of an EX4 file but do not have the budget for a paid reverse-engineering service, you have a few practical alternatives: 1. Re-code the Logic from Scratch (Recommended)
If the indicator is simple, use MetaEditor to look at the properties and try to replicate the logic from scratch.
If your EX4 file was created before using MT4 Build 509 or lower, it was compiled into byte code. For these older files, legacy tools like EX4 to MQ4 Decompiler 4.0.432 can often successfully restore the source code with relatively high accuracy.
Before 2014, MetaTrader 4 used an older compilation system. Early decompilers could easily reverse-engineer those old EX4 files.
You’ll stumble upon links to “free EX4 to MQ4 decompilers” – usually from shady file-sharing sites. Most are:
