## Self Matching Prevention

Self matching prevention is a risk management feature that prevents a trader from accidentally executing trades against their own orders. This often happens in high-frequency trading environments where multiple algorithms are operating simultaneously.

By identifying these potential self-trades before execution, the system can automatically cancel or adjust the orders. This is important for preventing artificial volume creation and ensuring that all trades are legitimate, arm's-length transactions.

It is a standard feature on most professional-grade exchanges. It helps maintain the quality of order flow data and the integrity of market statistics.
