Designed as an integral part of exchange software development for matching buy and sell orders from users in real time, a matching engine is at the core of their trading operations. The purpose of this blog post is to demonstrate how a typical crypto exchange matching engine works and why it is beneficial for users.
What is a Matching Engine, and How Does It Work?
A program that matches orders between buyers and sellers on a trading platform, such as a cryptocurrency exchange, is referred to as a matching engine or order matching engine architecture. It serves as the core of a trading platform, carrying out deals and monitoring orders.
As part of the matching process, buyers and sellers submit orders and then the matching software matches them with each other using some form of priority queue in order to keep track of the order flow.
When the engine uses a priority queue to match orders based on price and time-stamp, it is able to accomplish this easily and effectively. Additionally, the engine will typically maintain an order book, which includes a list of all pending orders. An order will be matched with any existing orders in the book when it is received by the engine.
As soon as a matching trade is identified, the engine executes it and notifies both parties of the outcome. Moreover, the engine will keep track of all open orders that have not yet been matched so they may be matched if a new order arrives.
To process large volumes of trades quickly and efficiently, matching engines utilize high-speed computer systems. These matching engines are capable of processing hundreds, if not thousands, of trades per second, enabling them to keep up with the rapidity of the market’s trading activity.
On cryptocurrency exchanges, there is often a tremendous amount of activity that must be monitored in order to maintain a high level of efficiency.

- A matching engine also has the potential to increase market openness, which is another advantage.

- Last but not least, a matching engine can also increase the liquidity of a market. This engine can assist in ensuring that there will always be someone willing to buy or sell at any given price by making it easier for buyers and sellers to find each other and trade quickly. Consequently, market participants will find it easier to enter and exit trades, and markets will run more smoothly.
Conclusion
