Order Matching
Order Matching: Connecting Buyers and Sellers
Order matching is the process of pairing buy and sell orders to execute trades on exchanges. It's like a digital matchmaker that finds the perfect trading partners for each transaction.
Order matching refers to the algorithmic process that pairs compatible buy and sell orders to execute trades at agreed prices on cryptocurrency exchanges. This system enables efficient price discovery and trade execution.
How Order Matching Works
Price-time priority typically matches orders based on best price first, then earliest submission time for orders at the same price level.
Order types including market orders, limit orders, and stop orders require different matching logic and execution priorities.
Engine optimization processes thousands of orders per second while maintaining fairness and regulatory compliance requirements.
