If you’ve heard the term, but are still not exactly sure about what a matching engine is or the technology behind them, this article seeks to provide a basic understanding on how they work.

What is a Matching Engine?

A matching engine is essentially the core mechanic of a digital exchange which matches up bids and offers to execute trades. They work by using one or more algorithms which keep a record of all open orders in a market and generating new trades if the two orders can be fulfilled by each other. A matching engine is able to support different order types, such as a limit order or market order and may have unique APIs as well as offering a wide range of other features.

These days, trading is almost entirely facilitated by electronic trading matching engines. The software supporting it is the most crucial part of any exchange as this is what enables users to trade with each other. Leading cryptocurrency exchange, B2BX.
