For users who need specific functionality that an existing EA provides but cannot obtain source code for it, developing a new EA from scratch is often the most practical option. While this takes time and programming skill, it provides full control, legal ownership, and avoids all the risks associated with decompilation.
Since full decompilation of new Ex4 is effectively impossible, consider: ex4 decompiler github
However, you can use specialized tools on GitHub to analyze or attempt recovery. 🛠️ GitHub Tool: EX4 Debug Decompiler

Document the entry rules, exit rules, indicator dependencies, and risk management (e.g., martingale, grid, or fixed stop loss).
Newer EX4 files are encrypted and optimized. Compiling removes human comments and replaces readable variable names with machine logic. Legal Risks:
