Astros employs a Price-Time Priority system, utilizing a First-In-First-Out (FIFO) methodology for matching orders.
Orders are matched when either of the following conditions is met:
A buy (bid) order price is equal to or higher than the best available sell (ask) order price.
A sell (ask) order price is equal to or lower than the best available buy (bid) order price.
A market order is submitted, and opposing limit orders already exist in the order book.
In all cases, orders with earlier timestamps receive priority at the same price level.
