Why Decompilation Is Difficult

MetaQuotes has intentionally made decompilation challenging:

  1. Obfuscation – Modern EX4 files use control flow obfuscation and junk code insertion.
  2. No Symbol Recovery – Variable names, function names, and comments are stripped during compilation.
  3. Build Incompatibility – EX4 compiled with build 600+ uses a completely different bytecode structure (similar to MQL5). Older decompilers (like build 224) only work on pre-600 EX4 files.
  4. Anti-Decompilation Features – Since build 509, MetaQuotes added checksum validation and anti-tampering mechanisms.
