The Pros and Cons of Using a Matchmaking Engine

© by

The matching engine is the central component of a trading platform, facilitating the efficient and rapid matching of buy and sell orders. In this article, we’ll look at the inner workings of a standard trade engine and talk about some of the challenges that exchanges face in keeping their engines up and operating.

Matching Engine and Its Benefits

A matching engine is a computer system that matches buyers and sellers in financial markets such as stocks, bonds, derivatives, or futures. It acts as an intermediary between buyers and sellers to find the best price for each side of a trade. The matching engine uses algorithms to evaluate order books and compare bids and offers from different exchanges to ensure the best possible execution for both sides of a transaction.

The order book matching engine is essential to any trading platform as it ensures that orders are executed quickly and efficiently. The speed and accuracy of a matching engine can make or break a trade, so exchanges must be sure to use reliable technology when they build their systems.

The major benefit of using a matching engine is speed—orders are matched quickly, providing better liquidity on the market. This improves pricing efficiency by reducing spreads and allowing traders to get better prices with fewer slippage costs. Matching engines also offer improved control over risk management since they can be programmed to reject orders if certain criteria are not met.

A matching engine may increase the market’s overall liquidity by streamlining the process by which buyers and sellers connect and conduct transactions. Additionally, a matching engine can reduce trading costs by reducing the need for manual order entry and processing. By facilitating interactions between traders located all over the globe, matching engines serve to expand the reach of financial markets. As a result, the market as a whole may become more globalized and competitive.

The Difficulties

However, there are a number of obstacles that must be overcome to ensure an exchange matching engine’s continued success. Data speed and latency are key factors since the engine must process large volumes of data quickly to provide accurate results. The technology must also be robust enough to handle sudden spikes in trading activity without crashing or slowing down. Network infrastructure and hardware upgrades may be necessary to keep up with increased demand.

Another challenge is ensuring that the matching engine works correctly. Exchanges are responsible for monitoring their engines and ensuring orders are executed swiftly and fairly, which requires additional time and resources devoted to system maintenance. Additionally, exchanges must be vigilant about minimizing illegal practices such as market manipulation through sophisticated algorithms that detect any suspicious activity.

Finally, running a matching engine can be expensive for smaller exchanges if they don’t have the necessary resources to develop and maintain their own system. For these reasons, many exchanges outsource their matching engine technology, which can be expensive but may be worth it in terms of increased efficiency.


In conclusion, a matching engine offers several advantages for traders and exchanges alike: improved liquidity and pricing efficiency, improved risk management, reduced trading costs, and access to global markets. Although challenges must be addressed, such as data speed and latency, network infrastructure issues, and the cost of running a matching engine, these benefits outweigh any potential drawbacks. As a result, more exchanges are turning to matching engines to keep up with increased demand from traders worldwide.
