The Order-Matching Engine SpringerLink
Spot matching allows participants to access firm pricing and obtain high certainty of execution. The process is key to the functioning of the FX market whereby brokers need to rely heavily on matching data using automated software. A multilateral trading facility (MTF) facilitates the exchange of financial instruments between several parties. A matching engine continually scans all orders on a given instrument and determines whether there is a potential match. The party that placed the order is notified when a matched order is filled through cancellation, fulfillment, or expiration.
The highest bid price is ordered first, followed by the lowest bid price. Orders with the highest bid price are executed first, whereas orders with equal bid prices are executed in the order in which they arrive.

The important thing to remember is that the goal of the OME is to match buy and sell orders fairly and efficiently. A system using the Pro-Rata algorithm also gives priority to the highest-priced buy order.
For example, if a large player wants to buy a lot of tokens, they can place a series of small buy orders. The most common algorithm is called the First-In-First-Out (FIFO) algorithm. Under the FIFO algorithm, the first buy order that is matched with a sell order is filled first. If there are multiple buy orders and multiple sell orders at the same price, the orders are filled in the order they were received. The rule for matching is simple, if there’s a price cross meaning someone is willing to buy at a price higher than or equal with the current selling price, these two orders are traded. The matching engine should also print out information about the trade when it occurs.
This matching engine is the foundation for different types of exchanges and trading venues. All orders at the same price level are filled according to time priority; the first order at a price level is the first order matched. Cancel orders are processed first, followed by market order, limit orders and stop order. This section discusses the rules used by the order matching engine to execute order. An order matching system or simply matching system is an electronic system that matches buy and sell orders for a stock market, commodity market or other financial exchanges.

For an exchange to be successful, its order matching engine (OME) needs to be able to quickly and accurately match buy and sell orders. In this post, we’ll take a closer look at what an OME is and how it works. We’ll also explore some challenges that exchanges face when building their OMEs.
Both have been adapted and extended for various types of products and use cases, but for brevity, I’ll only explain the basics here. A limit order that allows a partial fill will complete when the limit order is partially filled. As Figure 2 shows, limit order matching is also complicated by the presence of both limit and market orders.

A cancellation order cancels a limit or stop order (if the stop order has not converted to a limit order, in which case it cannot be canceled). Market orders cannot be canceled because their execution will take place immediately when there is a opposite order. Canceling a market order would be non-deterministic, so this is not supported. As for Bangladesh, well, their bowlers were shell-shocked by India’s approach.
