## Order Queue Priority

Order queue priority determines the sequence in which orders are executed within an exchange matching engine. Typically, exchanges follow a price-time priority model, where orders at the best price are executed first, and orders at the same price are executed based on their time of arrival.

In the context of derivatives, understanding this priority is crucial for ensuring order fills. Traders who submit orders faster gain a higher position in the queue.

This is why latency optimization is so closely tied to order queue placement. Failure to understand queue dynamics can lead to missed trades or unfavorable execution outcomes.
