Modern MetaTrader 4 builds, particularly those post-build 600, use stronger compilation techniques. Decompiling these files often produces unusable code or fails entirely.
Even if a legacy version of a "5.0 decompiler" is successfully run in an isolated environment, it will fail to process any modern .ex4 file. Instead of readable code, it will either crash, throw an error, or output broken, uncompilable syntax. Legitimate Alternatives to Decompilation
: Older decompilers (like version 4.0.432) were only effective for files compiled with build 509 or lower (pre-2014). ex4 to mq4 decompiler50 1 exe top

If you lost your source code but have proof of purchase, most developers will gladly supply a backup copy of the .mq4 file.
To understand why people search for a decompiler, it helps to understand how the MetaTrader 4 platform handles code: Even if a legacy version of a "5

There are several scenarios where an EX4 to MQ4 decompiler becomes essential:
