Matching Engine for an Exchange — What Is It?

Are you curious to learn more about matching engines? This article provides a complete overview of this technology, discussing its key features in detail.

What is a Matching Engine?

A matching engine is a computer system that matches buyers and sellers in an exchange. It is the core of the trading system, which enables the exchange to process orders, match them against available liquidity, and execute trades. The trade engine is designed to be fast, efficient, and reliable, allowing buyers and sellers to trade quickly and with confidence.

Utilizing algorithmic programming, the system stores and records all open orders in a market. If matched orders are found, it will then automatically execute the transaction.

Such engines can support different types of orders, such as market orders or limit orders, they may have unique APIs, and they also can offer a wide range of other features.

What Types of Matching Engines Are There?

On the exchange market, several exchange matching engines are generally used, with centralized and decentralized types being the most common. 

  • Decentralized type

This type of matching engine is created to match orders from several users in real time, but it does not depend on a central server. This type of matching engine uses a peer-to-peer network to match orders, which means there is no central point of failure, and the system is more resilient to attacks. 

  • Centralized type 

The centralized matching engine is the most commonly used type on the market. Major exchanges use centralized matching engines. It is designed to match orders from multiple users in real time. 

Each matching engine type has its own disadvantages and advantages. Typically, faster and more efficient matching engines are centralized but more vulnerable to attacks. Unlike centralized engines, decentralized engines are more resilient to attack but slower and less efficient.

Essential Characteristics of a Matching Engine.

In order to determine which order-matching engine is best for their exchanges, business owners must compare the available options. Here are some key characteristics of order-matching engines: 

  • How many requests are fulfilled in a second?

Trusted providers offer OMEs that process more than 10 000 requests per second.

  • What is the minimum trade processing?

The best engines execute orders in 0.05 milliseconds or less, allowing traders to use various trading strategies.

  • Does the provider offer 24/7 support?
