## Matching Engine Logic

Matching engine logic refers to the specific rules and algorithms an exchange uses to pair buy and sell orders. These rules define how orders are prioritized, such as price-time priority or pro-rata allocation.

Understanding the logic is essential for traders to predict how their orders will be filled in various market conditions. It influences the behavior of market makers and the overall liquidity of the venue.

The design of the matching engine can also impact the speed of execution and the fairness of the market. It is a critical technical component that shapes the trading experience for all participants on the platform.
