An EX4 decompiler is a software tool designed to take an .ex4 file and attempt to recreate the source code in a form that resembles the original MQL4 code. This process is not always perfectly reversible due to the nature of compilation and the optimizations performed by the compiler. However, a good decompiler can retrieve a significant portion of the original code, making it a valuable tool for analysis, learning, and recovery of lost source code. ex4 decompiler github
