Order Matching Design Patterns

Algorithm

Order matching algorithms represent the core logic governing trade execution within electronic exchanges, particularly crucial in cryptocurrency and derivatives markets where speed and fairness are paramount. These systems determine the priority of orders based on price-time priority, pro-rata allocation, or more complex criteria like order size and market maker incentives. Efficient algorithm design minimizes latency and adverse selection, directly impacting market quality and liquidity provision. Modern implementations increasingly incorporate deterministic execution to enhance transparency and auditability, addressing concerns around front-running and manipulation.
