根据相关工具的技术介绍，EX4反编译MQ4工具的核心技术在于其能够。这意味着，即使原始代码被编译和优化，工具仍试图重建其核心逻辑。
The is necessary because it bridges the gap between old decompiler technology and new MetaTrader compilation standards. Crucial Considerations and Ethical Usage
: Newer versions use a more secure compilation process that generates complex binary code rather than simpler bytecode, making full recovery nearly impossible for older tools.
