Lesson 18: Understanding Matching Engines in Trading
Lesson Intro:
The world’s largest crypto exchange, Binance, entered into a collaboration agreement with our nonprofit, the Prison Professors Charitable Corporation. With this collaboration, we’re able to provide justice-impacted people with a great resource they can use to learn about cryptocurrency, decentralized finance (DeFi), Web3.0, Artificial Intelligence, and other topics that relate to the digital economy. The agreement is part of our nonprofit’s ongoing efforts to help people prepare for success after prison.
Some people have access to our videos, others do not. If a staff member in your prison will authorize videos, invite them to contact Prison Professors for information on how we can send DVDs with additional educational materials to help people learn–and potentially an in-person presentation in your facility.
Each lesson includes critical thinking questions and a glossary. We encourage participants to use these lessons, and to memorialize their learning path by building a profile on Prison Professors Talent. More information on how to build a personal profile at the end of this workbook.
18: Understanding Matching Engines in Trading
TL;DR
TL;DR: Prison Professors partners with Binance to educate justice-impacted individuals on trading. Matching engines efficiently pair buyers and sellers in financial markets, ensuring fair and swift trade execution. Key algorithms include FIFO, Pro-Rata, and TWAP. This initiative helps prepare for successful reentry.
Key Takeaways
- A matching engine is a sophisticated system that brings together buyers and sellers in financial markets.
- Modern matching engines can match and execute trades fairly and swiftly, contributing to a better and more responsive trading environment.
- There are different types of algorithms defining how a matching engine prioritizes and executes orders. Common examples include FIFO, Pro-Rata, and TWAP.
Have you ever wondered how buy and sell orders magically turn into completed trades on stock or crypto exchanges? Well, the secret sauce behind this is something called a matching engine.
What Is a Matching Engine?
At its core, a matching engine is a sophisticated software system that brings together buyers and sellers in financial markets. Imagine it as the matchmaker of the trading world, pairing those looking to buy with those ready to sell, and vice versa. Its primary mission is to execute trades swiftly and efficiently, creating a level playing field for market participants.
Matching Engines vs. Traditional Methods
In the past, trading and order matching were heavily based on phone calls and manual processes. Such systems were significantly more time-consuming and prone to human error when compared to the sophisticated matching engine systems we use today. Modern matching engines can match and execute trades fairly and swiftly.
How Does a Matching Engine Work?
Picture a bustling marketplace with traders shouting bids and offers. In the digital realm, this chaos is replaced by a calm order book. Traders enter their intentions to buy or sell, recording them in the order book. This is where the matching engine steps in, analyzing the landscape and connecting compatible orders.
The matching algorithm, the brain behind the operation, follows predefined rules dictating the order of priority. One of the most common rules is the so-called “first-in, first-out” (FIFO). Similar to getting in line at the grocery store, the orders that arrive first are prioritized. Another approach, “Pro-Rata,” favors larger orders, ensuring they enjoy a proportionally larger share of available liquidity.
Order Matching Algorithms
Order matching algorithms define the functioning of a matching engine. Let’s peek into a few examples:
1. First-in, first-out (FIFO).
Also known as “first-come, first-serve” (FCFS), FIFO represents the classic algorithm that prioritizes orders based on their price and creation time. When multiple orders are created at the same price, the order that arrived first gets matched first, ensuring fairness in execution.
2. Pro-Rata
The Pro-Rata algorithm adds a twist by favoring larger orders. This means that if two orders are pending at the same time and price, the one with a larger traded quantity will be executed first.
3. Time-Weighted Average Price (TWAP)
TWAP-based algorithms calculate the average price of all orders within a certain period and execute multiple trades gradually to achieve that average price. TWAP algorithms can reduce the impact of large orders by splitting them into smaller orders that will eventually reach the same average price as the initial order.
Types of Matching Engines
1. Centralized matching engine
Centralized matching engines offer real-time matching with remarkable speed and efficiency. Operating on a single central server, they swiftly process orders, making them ideal for high-traffic exchanges where quick matching is crucial.
2. Decentralized matching engine
Decentralized matching engines operate on a peer-to-peer network, providing resilience against attacks. While they contribute to a more secure trading environment, they might sacrifice some speed and efficiency compared to their centralized counterparts. The absence of a central server minimizes the risk of breaches, making them a safer alternative.
Choosing the Right Matching Engine
Speed
For platforms with high trading volumes, a centralized engine excels in quick order matching. In contrast, a decentralized engine, reliant on a peer-to-peer network, may exhibit slower performance.
Security
While a centralized engine is susceptible to attacks due to its reliance on a central server, a decentralized engine, operating on a distributed network, offers more resilience against potential breaches.
Fees
Centralized engines typically incur higher fees due to increased infrastructure and resource requirements. On the flip side, decentralized engines, functioning on a peer-to-peer network, generally come with lower fees.
Why Matching Engines Matter
In the bustling world of trading, where milliseconds can make a difference, matching engines play a pivotal role. Here’s why they matter:
1. Efficient order execution
A good matching engine provides swift order execution. The ability to process orders rapidly is crucial, especially in a landscape where every millisecond counts.
2. Fairness and transparency
With predefined algorithms dictating order priority, matching engines uphold fairness, promoting transparency in trade execution. Traders can trust that their orders are processed impartially based on established rules.
3. Market liquidity
By seamlessly connecting buyers and sellers, matching engines can contribute to market liquidity. This liquidity, facilitated by efficient order matching, can lead to a more responsive market environment.
Closing Thoughts
Although matching engines are often overlooked, they stand as a testament to the precision and sophistication underlying modern trading platforms. A matching engine is the unseen force ensuring that the gears of the market turn smoothly, providing traders with the ability to transact with speed, fairness, and efficiency.

Advocacy Initiative:
We encourage participants to begin memorializing the ways they are using time in prison to prepare for success upon release. I encourage participants to create a personal profile by:
- Writing a simple biography
- Writing a daily journal to show all that you’re learning
- Writing book reports that memorialize the books you read
- Writing a release plan to show the ways you’re preparing for success upon release
These strategies helped me immensely once I got out. By using my time wisely inside, I was able to raise capital, build businesses, and succeed in ways that few people would think are possible for someone who served multiple decades in prison. Anyone can do the same—if they prepare first.
If you’d like to follow in the same footsteps, I encourage you to begin building your personal profile. Get started by sending an email message to our team at:

Dear Interns,
My name is xxx, and I am in prison. I would like to begin showing the strategies I am using to prepare for success upon release. Please send me a Release Plan Workbook, and any other books that will help me prepare for the job market. After receiving those workbooks, I will begin building my profile to show others how I am using my time inside to prepare for success outside.
