## Order Flow Filtering

Order Flow Filtering involves the systematic screening of trade orders at the exchange or protocol level to ensure compliance with market rules and risk parameters before they enter the matching engine. This process helps maintain orderly markets by rejecting orders that do not meet minimum size requirements, price tick increments, or margin sufficiency criteria.

In high-frequency trading and decentralized derivatives, this filtering is essential for managing toxic flow and preventing adverse selection. By analyzing order flow in real-time, platforms can protect against spoofing, layering, and other manipulative practices that distort price discovery.

It ensures that the order book remains representative of genuine market sentiment rather than adversarial noise. This mechanism is critical for the stability of margin engines, as it prevents under-collateralized orders from impacting the system.

Effective filtering enhances the overall efficiency and fairness of the trading venue.
