Order Queue Management

Order queue management refers to how exchanges organize and prioritize the execution of orders in their matching engine. Most exchanges use a price-time priority system, where orders at the best price are executed first, and if prices are equal, the order that arrived first is executed first.

Efficient queue management is essential for ensuring fairness and maintaining the integrity of the market. Traders who understand the rules of the queue can optimize their order placement to increase their chances of being filled.

In high-frequency environments, the exact position in the queue can be critical. This involves understanding the exchange's matching logic and how it handles order updates and cancellations.
