These tools might be free to download and can analyze the metadata of an EX4 file (such as the number of buffers in an indicator or the timestamp of compilation).

This hybrid model uses GitHub as a distribution platform for what is essentially a paid service.
Instead of looking at the code, look at the behavior. You can deduce a strategy's logic by analyzing how the EX4 interacts with the market: ex4 decompiler github
Instead of extracting the exact code, observe what the indicator or EA does on your chart. Note its entry conditions, exit parameters, and risk management style. You can easily write a fresh, clean MQ4 or MQ5 script using these rules, or hire a freelancer on MQL5.com to build it safely. Utilizing Open-Source Repositories
