When you write an EA in MetaEditor, you save it as an .mq4 file. Then you compile it into an .ex4 file, which MT4 actually runs. Developers distribute .ex4 files specifically to .
These forums have massive threads dedicated to sharing free .mq4 files. You can upload your .ex4 file to specific "coding help" threads, and experienced programmers might recognize the indicator and provide you with the original open-source .mq4 file.

Converting (compiled) to MQ4 (source code) is a process known as decompiling . While many tools online claim to do this for free, the reality in 2026 is that it is technically difficult and often legally restricted. 1. The Reality of EX4 to MQ4 Conversion
There is, however, a legitimate alternative to conversion that is free and ethical: writing the code from scratch. If a trader understands the logic of an EA—perhaps by observing its behavior on a chart or reading a description—they can hire a coder or learn to program the strategy themselves. This method, while requiring more effort, results in a clean, owned, and modifiable MQ4 file without relying on questionable decompilation tools.
