If you want to replicate a specific feature or strategy from your EX4 file, I can help you write the code manually. To help me get started, let me know: What does the EX4 file use? What are the entry and exit rules of the strategy?
| Original MQ4 Feature | After Decompilation | |----------------------|----------------------| | Meaningful variable names ( RSI_Value ) | var_1 , var_2 , var_300 | | Comments explaining logic | All comments removed | | Clean loops and conditions | Goto statements and spaghetti logic | | Proper function structures | Broken or missing functions | | Compiles successfully | Fails to compile |
Converting a commercial EX4 file that you purchased or downloaded without the author's explicit permission violates intellectual property laws. How To Convert Ex4 To Mq4 Free
Decompiling EX4 files without permission is legally and ethically complex:
Converting an EX4 to MQ4 without permission is: If you want to replicate a specific feature
For the technically inclined, you can use a free debugger like or OllyDbg to attach to the MT4 process and step through the EX4 bytecode. This is extremely time-consuming and requires assembly language knowledge. It produces no MQ4 file—only a mental model of the logic.
If you cannot get the source code for free, you can try these practical alternatives: | Original MQ4 Feature | After Decompilation |
Open the "Data Window" (Ctrl+D) in MT4 to view the exact output values the indicator generates.
If the EX4 file was compiled without excluding debug information, some older versions of MT4 might allow limited recovery:
