Accuracy and Limitations – What 4.0.432 Can and Cannot Do

Quality Limitations

: Even if a decompiler works, the resulting MQ4 code is often difficult to read — variable names are lost, logic can be scrambled, and the output may not compile without extensive manual correction.

Enhanced Decompilation Accuracy

: The new version boasts enhanced algorithms that improve the accuracy of decompilation. This means that users can expect more precise and readable .mq4 code from their .ex4 files.

If you have 50+ EX4 files in a folder, the new version processes them sequentially without memory leaks—a major improvement over the 4.0.428 beta.

Many users reported that decompiled indicators failed to compile due to mishandled SetIndexBuffer() or IndicatorBuffers() calls. This update explicitly patches those errors, producing compile-ready MQ4 code.

If you're trying to recover your own lost code, your best bet is searching for old backups or contacting the original developer, as these automated tools rarely provide a functional result for current MetaTrader versions.

) for your own indicator, your best options are to contact the original developer or hire a professional programmer to rewrite the logic from scratch by observing the indicator's behavior.
