## Input Validation Protocols

Input validation protocols are the set of rules and checks applied to all data entering a system to ensure it meets the expected format, range, and type. This is a critical cybersecurity practice in trading software, where malformed data can lead to crashes, security breaches, or incorrect calculations.

Validation ensures that numbers are within reasonable bounds, strings are correctly formatted, and all inputs are sanitized to prevent injection attacks. In the context of financial systems, this also includes logical validation, such as checking that a price update is within a realistic range of the previous price.

By enforcing these rules at the entry point, developers can protect the integrity of the entire system. It is a proactive approach to security that stops threats before they reach the core trading logic.

In a world of programmable money, input validation is the barrier that prevents errors from turning into financial disasters. It is a foundational practice for building secure and resilient financial applications.
