Advancements in MQL5 allow developers to implement cryptographic algorithms directly, improving security and system stability. Custom implementations provide greater control, tailoring to specific tasks, and reducing vulnerabilities. Cryptography is crucial for APIs and trading system security, requiring a thorough understanding of algorithms.

A significant issue arises with API signature generation, where MQL5's native hashing functions may not align with cryptocurrency exchange requirements, causing authentication failures. This often necessitates custom SHA-256 implementations to ensure compatibility with exchanges like Binance or Bybit.

Custom implementations not only resolve compatibility issues but also offer performance optimization, crucial for high-frequency trading. Optimizing SHA-256 for trading can involve recognizing and reusing consis...
