I just saw the same project here on this side so i just copy it. I hope you do not mind. Probably someone has it already ready.
"I would like a decompiler program for metatrader ex4 files. The ex4 files should be decompiled to mq4 format.
The mq4 language is very similar to C language and any experienced C/C++ or java programmers should be at ease with the language.
The program should take any ex4 file and convert it back into mq4 format.
I have uploaded examples of a compiled file (ex4) and raw uncompiled file (mq4).
More about the Mq4 language, the compiler and metatrader can be found at [url removed, login to view]
