Check if specialized order types like Trailing Stops, One-Cancels-the-Other (OCO), and Iceberg orders are available or planned for future implementation. In this article, we’ll give you an insight into what an order matching engine is, the mechanics behind it, and what to pay attention to when choosing one for your exchange or dark pool. It is also important to stay informed about new investment strategies, tools, and market information to improve your stock trading skills continuously.

This is where buyers and sellers come together to complete a trade. The matching engine ensures that transactions occur quickly and efficiently, with the best price for both parties. A few different types of matching engines are commonly used on exchanges. The most common is the centralized matching engine, which most major exchanges use. This engine is designed to match orders from multiple users in real-time. It typically uses the first-come, first-serve algorithm to match orders, but some exchanges may use a different algorithm.

The CFTC monitors electronic trading to identify potential risks to market stability and takes action to prevent or mitigate these risks. The National Association of Securities Dealers Automated Quotations (NASDAQ) became the world’s first electronic stock exchange when it opened for business in 1971. It was designed to make trading more streamlined and effective by automating the order execution process.


Electronic trading emerged as the preeminent method of conducting business over the 2000s in most of the world’s financial markets. High-frequency trading, also known as HFT, is a relatively recent development in trading strategies. It is characterised by the use of algorithms to complete trades in a matter of milliseconds. Worries arose regarding the stability and fairness of the market because of this, and as a result, regulators started implementing new laws to address these issues. Established in the United Kingdom in 1801, the LSE adopted electronic trading in 1997, enhancing market efficiency and providing a modernized platform for trading a wide range of financial instruments. Launched in the United States in 1971, NASDAQ was one of the first major stock exchanges to implement electronic trading from its inception, revolutionizing the way securities were bought and sold.

Matching engine algorithms follow different execution models by prioritising first trade proposals or those with more significant volumes. All exchange activities are managed daily by B2Trader’s administrator who ensures that they are straightforward and user-friendly for the exchange’s clients. Apart from controlling trading and withdrawal privileges, the admin module enables you to see a user’s login and transfer history and their asset holdings and aggregate currency information. Centralized engines typically have higher fees than decentralized engines. This is because they require more infrastructure and resources to operate.

Information about each order placed, including the order type, price, quantity, time of order placement, and any modifications made to the orders. This site includes all necessary hardware, software, and network infrastructure to support trading operations. The first ETS was developed in the 1960s, and the technology has since evolved.

This is because exchanges typically have a lot of users who are all trying to buy or sell at the same time. If an exchange did not have a matching engine that could handle this high traffic volume, it would quickly become overwhelmed and unable to function properly. These features make DXmatch a powerful and reliable choice for trading venues and exchanges seeking an efficient and high-performance order matching engine. DXmatch is Devexperts’ proprietary order matching engine designed for ultra-low latency and high throughput applications.

Creating the Engine

Following a prolonged development and integration phase, the second version of the B2Broker matching engine was introduced in 2019 after incorporating ground-breaking technological advances. There’s quite a variety of algorithms for auction trading, which is used before the market opens, on market close etc. but most of the time, the markets do continuous trading. The fee structure is another factor to consider when choosing a matching engine. The fee may be a fixed amount or a percentage of the total order value. In addition, the matching order system should be efficient so that buyers and sellers benefit equally, and the volume of orders is maximized.

This is why since day one, we have been focused on developing a fair and powerful matching engine. In these applications, bare metal systems that are co-located in exchange data centers are essential. In these cases, even the shortness of the cables used to connect client servers to exchange matching engines can confer a minuscule advantage on one participant over another. Every time a trade is made, the balance between the best available buy/sell prices and volumes thereof is altered as liquidity is removed, thus setting a new prevailing market price.

  • Additionally, limit orders get preference over market orders at the same price point.
  • You’ve placed a purchase order for $10,000 and a sell order for $11,000 in Bitcoin.
  • The system offers various risk management tools, such as stop-loss orders, position limits, and margin requirements.
  • The most common is the first-come, first-serve algorithm, but a few other options are worth considering.
  • Familiarize yourself with concepts such as buying and selling stocks, market orders, limit orders, and stop-loss orders.

This system works by finding a matching order request and settling it according to the market order requests by the trader. For example, if a trader wants to enter a market position by buying ten shares of Microsoft stock, the matching engine will find a buyer willing to sell ten shares of Microsoft at the market price. Due to the engine’s exchange matching engine enhanced stability and performance, APIs may now be developed more rapidly. B2Broker’s new trading and public APIs (Websocket/Rest) significantly speed up the processing of trading and shared data access requests. This improves overall system performance by substantially speeding up the processing of trade and public data queries.

What is a Cryptocurrency Matching Engine and How Does it Work?

However, it has the drawback of being more difficult to adopt and scale. Which strategy is preferable is determined by the unique demands of the trade. In general, centralized exchanges are better suitable for small to medium-sized low-volume exchanges, whereas https://www.xcritical.com/ decentralized exchanges are better suited for big high-volume exchanges. The order book is the log that lists all market order requests when a trader wants to open/close a position. The matching engine scans through the order book to pair buyers with sellers.

He specializes in personal finance, stock market, news articles. The pro-rata algorithm works by first Identifying the best bid and offer prices in the order book. Unauthorized access to trading systems or data results in theft, data manipulation, or disruption of normal operations.

This engine is designed to match orders from multiple users in real-time, but it does not rely on a central server. This means there is no central point of failure, and the system is more resilient to attacks. Investors actively trading in exchange markets seek ways to tackle the inefficiencies of the trade market.


The Pro Rata algorithm pairs an incoming market order with limit orders placed at the same price level in proportion to the size of those limit orders. It executes orders in strict accordance with the price at which they were placed, their size, and the time of placement. The number of assets/lots of the incoming market order is distributed in proportion to the size of limit orders.

An explanation of how Crossbeam’s matching engine determines matches at the person and company levels. Exchanges using centralised matching algorithms usually charge higher fees because they deploy more resources to keep their servers safe and fulfil and sell orders at a higher frequency. Decentralised ones that use a peer-to-peer network are usually less expensive. Tamta is a content writer based in Georgia with five years of experience covering global financial and crypto markets for news outlets, blockchain companies, and crypto businesses. With a background in higher education and a personal interest in crypto investing, she specializes in breaking down complex concepts into easy-to-understand information for new crypto investors.

Generally they use First-In First-Out kinds of algorithms because they maximize the number of effective orders. The most commonly used ones would be Price/Time priority and Pro-Rata. Both have been adapted and extended for various types of products and use cases, but for brevity, I’ll only explain the basics here. This section details parts of the program that could be improved in a subsequent release and features that could be added.
