A decompiler is a software tool that attempts to reverse the compilation process. When an MQL4 developer writes code (MQ4), they compile it into a binary format (EX4) that the MT4 terminal can execute. This process removes comments, optimizes logic, and converts human-readable code into bytecode.
A decompiler aims to reconstruct the original source code from this bytecode. However, due to the nature of compilation, the result is rarely identical to the original. Instead, you get a reconstructed version—often filled with generic variable names (e.g., var_1, var_2) and missing original comments or structure. Many GitHub repos provided only an
Decompilation is a complex process. Compiled files (EX4) do not directly translate back to their original source code (MQ4) due to the compilation process, which includes optimizations and loss of high-level language constructs. Decompilers aim to reverse this process, but the output may not perfectly match the original source code. The complexity of the decompilation process depends on the decompiler's sophistication, the compiler's optimizations, and the presence of certain programming constructs.
