## Queue Priority Rules

Queue priority rules define the order in which trades are executed when multiple participants have orders at the same price level. Most exchanges use a price-time priority system, where the first order placed at a specific price is the first to be executed.

This makes speed and timing critical for traders who want their orders to be filled. In derivatives, understanding these rules is essential for those placing large limit orders, as they need to know where they stand in the queue.

Some exchanges offer specialized matching algorithms to prioritize certain types of orders, which can change the dynamics of the market. It is a foundational element of exchange architecture that dictates how liquidity is consumed.
