Ex4-to-mq4 V4 Decompiler Version 4.0.5 Full [work]
Key Points:
-
Functionality: The primary function of this decompiler is to convert .ex4 files, which are compiled versions of MQL4 programs used in MT4, back into .mq4 files. This process can be useful for recovering the source code of a program, allowing for its modification or study.
-
Version 4.0.5: The version number indicates a specific release of the software, suggesting ongoing development and updates to improve functionality, compatibility, or to fix bugs.
-
Usage in Forex Trading: In Forex trading, MQL4 programs (Expert Advisors, indicators, scripts) are commonly used to automate trading strategies or analyze market data. Being able to decompile .ex4 files can be crucial for traders who have lost the source code of their programs or wish to understand how a particular piece of code works.

If You Need MQL4 Source Code
Legitimate options:
- Contact the original developer for the source
- Write your own implementation from scratch
- Use open-source alternatives from GitHub or MQL5 Code Base
What is the Ex4-to-mq4 V4 Decompiler?
At its core, a decompiler is a reverse-engineering tool. The Ex4-to-mq4 V4 Decompiler takes a compiled EX4 file (the executable that runs inside MT4) and attempts to recreate its original MQ4 source code. Version 4.0.5 is widely regarded as one of the most stable and complete releases in the decompiler’s history. Key Points:
The keyword "Full" in "Version 4.0.5 Full" typically indicates that the software includes all features without restrictions—no time limits, no watermarked code, and full support for all MT4 builds (up to a certain threshold, as MetaQuotes constantly updates its compiler).
The Unspoken Deal
When you run Ex4-to-mq4_V4_4.0.5_Full.exe, you are making a pact. Functionality : The primary function of this decompiler
You agree that 92% of the output will compile without errors. You accept that the remaining 8% will be goto statements so tangled they resemble a C++ rogue-like. You ignore that the decompiled StopLoss logic might be inverted, because the original used Bid - Points * 10 and the decompiler normalized it to Ask + .... You live with the fact that obfuscated EAs — those with while loops masquerading as if chains — will output something that looks valid but trades like a cat on a keyboard.
But you run it anyway. Because somewhere, in a .mq4 file you were never meant to see, lies the answer to why your 99% quality backtest turned into a margin call.
Stage 3: Code Synthesis
The decompiler generates MQ4 syntax, complete with function declarations, event handlers (OnTick(), OnInit(), OnDeinit()), and preprocessor directives. The output is not perfect—comments and original formatting are lost—but it compiles back into a functional EX4 in most cases.
Important Legal & Ethical Considerations
- Terms of Service Violation: Decompiling .ex4 files typically violates MetaQuotes' license agreement
- Copyright Infringement: Most .ex4 files are proprietary; decompiling them without permission is illegal in many jurisdictions
- Malware Risks: "Cracked" or "Full" versions distributed on forums often contain trojans, keyloggers, or ransomware
