Say you are a trader and you have two orders on the market: one to purchase BTC for $10,000 and the other to sell it for $11,000. Before you realize it, both of your orders have been carried out. This happens quite often.
While you might believe that your purchases were automatically completed at the most reasonable costs, a lot more activity is happening in the background. The order matching engine, the backbone of every cryptocurrency exchange, will be discussed in this article. We'll go through how it works and why it's vital to guarantee rapid and precise order execution.
What Is an Order Matching Engine?
On a cryptocurrency exchange, buy and sell orders are matched by a software component called an order matching engine. It is the essential element of any exchange and enables buyers and sellers to transact in cryptocurrencies quickly and effectively.
The order matching engine functions by continuously scanning the order book for new orders. The algorithm will try to match an order with another order in the book. The request will be placed in the order book and held until the next order comes in that can be connected with it when there are no matching orders. If a fit is discovered, the transaction will be carried out, and both sides will be alerted.
How Does an Order Matching Engine Work?
The most important part of any cryptocurrency exchange is the order matching engine. It is in charge of quickly and effectively matching buy and sell orders.
A crypto matching engine has to be capable of handling a lot of orders quickly without hiccups. Additionally, the engine must be able to handle faulty or malicious orders. These factors make the creation of an order matching engine a difficult endeavor.
For order matching, a variety of algorithms may be applied. The First In First Out (FIFO) algorithm is widely used. This method essentially connects them based only on the time that each order was received. The first order that can be paired with the one that arrives first will be completed.
The Price Time Priority (PTP) algorithm is another widely used method. This algorithm considers the cost and the timing of the orders. It will favor older orders while also matching orders based on pricing. This guarantees that orders are not kept in the book for too long.
The exchange's requirements determine the algorithm which should be used. Though some exchanges might need to match lots of orders swiftly, others could need to ensure that all instructions are linked equally.
Role of The Order Book
All buy and sell orders that were made on an exchange are listed in the order book. The order book may be viewed as a collection of orders. It helps match incoming orders with current ones and is managed by the order matching engine.
The buy and sell sides make up each part of the order book. A summary of orders placed by buyers or sellers is included in each section. The price of the orders determines the order of the listings.
An order book is a vital tool for traders since it gives them knowledge of the state of the market at any given time. Orders may be placed using it, locations can be tracked, and price changes can be observed.
Developing an Engine
Several alternative strategies could be employed when creating an order matching engine. Using a centralized design, where a single server processes all charges, is one strategy. The entire system will shut down if the server crashes. This strategy has the benefit of being simple to scale and apply. But it has the drawback of being susceptible to a particular point of failure.
Utilizing a decentralized architecture, where a different node processes each order, is an alternative strategy. This strategy can function even if some nodes collapse, making it more resilient to breakdown. Its drawback is that it is more challenging to scale and more difficult to implement.
Which strategy is better is based on the specific requirements of the specific exchange. Decentralized exchanges are ideally equipped for big exchanges with high volume, whereas centralized exchanges are generally better for smaller to medium-sized exchanges with low demand.
How Can I Find a Good Order Matching Engine for My Cryptocurrency Exchange?
When selecting an order matching engine for your crypto exchange, there are a few factors to consider. The main factor is speed. You need an engine that promptly and properly matches all orders without delays.
Reliability is yet another factor to take into account. It would be best if you were looking for an engine that can appropriately match orders. A good engine should have a solid level of preciseness to ensure that there are no order mismatches.
And lastly, you need a dependable engine. A good engine should be able to manage a lot of traffic and continue to run even when overloaded. An engine that will break or have other issues is not acceptable.
