Use modern, clean MQ4 syntax to rebuild the script from scratch. This guarantees that your code runs smoothly on modern MT4 builds, remains fully customizable, and stays free of bugs introduced by decompilation errors.
Any decompiler that claims to work on a post‑2013 EX4 will almost certainly produce code that is . Functions may be misidentified, loops may be broken, and the control flow may be completely wrong. If you try to recompile the “recovered” MQ4 code, it will likely fail with dozens of errors. And even if it compiles, there is no guarantee that the resulting EA will behave the same as the original. decompile ex4 to mq4 github work
