Order Priority

Order priority is the hierarchy established by an exchange to determine which orders get filled first. While FIFO is common, other systems exist, such as price-time, size-priority, or a combination of these.

Understanding the priority rules is crucial for market makers who want to ensure their quotes are filled. If an exchange uses a pro-rata system, larger orders may receive a higher percentage of the trade volume.

This can influence the strategies that participants use to gain an edge. Order priority ensures that the matching process remains orderly and follows the rules established by the exchange's governance.

It is a fundamental component of market design that directly impacts participant behavior.
