Order Matching Engine

An order matching engine is the core software component of a digital asset exchange that continuously compares buy and sell orders to facilitate trades. It operates by maintaining an electronic order book, which lists all active limit orders for a specific trading pair.

When a new order arrives, the engine checks for a match based on the specified price and quantity parameters. If a match is found, the engine executes the trade and updates the order book accordingly.

This system is designed for extreme speed and low latency, as it must process thousands of transactions per second to maintain market efficiency. It serves as the primary mechanism for price discovery in decentralized and centralized exchanges alike.

The engine must be robust against system failures to prevent catastrophic loss of funds or incorrect trade execution.
