Ex4 To Mq4 4 0 432: How to Decompile EX4 Files to MQ4 Files

EX4 files are compiled versions of MQL4 source code files that are used to create expert advisors (EA), technical indicators and scripts for the MetaTrader 4 trading platform. MQ4 files are the original source code files that can be edited and modified by the user. Sometimes, traders may want to decompile EX4 files to MQ4 files for various reasons, such as learning from other developers, modifying existing EAs, or recovering lost source code. However, decompiling EX4 files is not a straightforward process and requires some knowledge and tools.

How does it work? In MetaTrader 4 up to build 509, the source code in MQL4 was compiled into so-called byte code. This is similar to the way the Java Virtual Machine or the modern .NET Framework compiler works. Programs compiled in this way can be unambiguously mapped to source code with a few exceptions (variable and function names, comments). This is exactly what the decompiler does.

In February 2013 build 600 of MetaTrader 4 trading terminal was released, where the concept of executable code generation was radically changed. From now on the source code is compiled directly into binary code, just like C++ compiler generates .exe files. Thus, you can use a decompiler to reconstruct the source code of almost any EX4 file created in 2012 and earlier. For later files, you should use an online decompilation service.

Where to download the decompiler?

You can easily find a link to download the decompiler version 4.0.427.4 on the Internet. You can download this software absolutely for free. However, you can still find offers to buy such a decompiler and use it for modern EX4 files compiled by the actual MetaEditor builds. So what is behind such offers? It's important to understand that all the 100% offers to buy a decompiler are scams. There is no decompiler for MT4 build 600 or newer. Moreover, its creation is impossible in principle. When you pay money to such people, at best you will get an obsolete decompiler that can be downloaded free of charge, and at worst you will get nothing.

So what to do? How should the EX4 files be decompiled today?

There is a solution to this problem. Nowadays, the decompiling of EX4 files is done manually by teams of skilled professionals. The most famous such team is Those guys have been working since 2005 and have huge experience in restoring source code of their EX4 and EX5 files. However, not every file can be decompiled. However, in about 85% of cases it is possible. In order to determine whether your EX4 file can be decompiled, fill in this form.


Decompiling EX4 files to MQ4 files can be useful for traders who want to learn from other developers, modify existing EAs, or recover lost source code.
