As of late 2025, the official MetaTrader 4 build numbers are around 1420–1450. Build 40432 would correspond to a version from the distant future or a fake label. No legitimate MetaQuotes EX4 file carries that build marker.
A decompiler is a tool that converts compiled code (like EX4) back into its original, human-readable form (like MQ4). Decompilers analyze the compiled code, identify patterns, and reconstruct the original code.

You can use for some data, but for logic, you may need to rewrite the EA based on observed behavior. This is legal if you do not copy literal code.

You can think of it like a software developer writing source code ( .mq4 ) and then compiling it into an application ( .ex4 ) that users can run.
MetaQuotes periodically updates MetaTrader 4, enhancing security and changing the compilation structure. Older decompilers often fail on newer builds, leading to syntax errors or corrupted code.
