A: You can, but any programmer who claims to do this is likely using the same unreliable decompilers and charging you for the result. You will not receive clean, commented source code.

The short, direct answer is: However, the full explanation is more nuanced. This article will explore why conversion is nearly impossible, the risks involved, the legitimate alternatives, and the rare exceptions where partial recovery might be possible. Part 1: Understanding the Technical Barrier – Why EX4 to MQL4 Conversion is Not Trivial To understand why you cannot simply "convert" an EX4 file, you must understand what compilation means in the context of MetaTrader 4. 1.1 MQL4 is a High-Level Language, EX4 is Bytecode Think of MQL4 as a recipe written in English (human-readable).
