## Toxic Flow Detection

Toxic Flow Detection involves identifying and filtering out order flow that is likely to be harmful to liquidity providers. Toxic flow is characterized by a high probability of informed trading and can quickly deplete a market maker's capital if not managed correctly.

Advanced detection techniques use machine learning and statistical analysis of order book data to flag suspicious patterns or high-conviction directional trades. By identifying toxic flow, liquidity providers can temporarily widen their spreads or stop quoting entirely to protect themselves from adverse selection.

This is a critical defensive capability for maintaining the integrity and profitability of market-making operations in high-frequency environments.
