Overview
exchange-lab is a high-performance trading exchange simulation designed to replicate the core mechanics of modern financial markets. It focuses on speed, efficiency, and real-time data flow, making it a practical exploration of low-latency system design.
The project implements an in-memory matching engine capable of handling order placement, matching, and execution with minimal overhead. Alongside this, it provides real-time market data streaming to simulate a live trading environment.
Key Features
-
In-Memory Matching Engine
Efficient order matching using optimized data structures for minimal latency. -
Order Book Management
Supports limit orders with dynamic bid/ask tracking. -
Real-Time Market Data
Streams live updates for trades and order book changes. -
Low Latency Design
Built with performance-first principles using Node.js and Redis. -
Scalable Architecture
Designed to handle increasing loads with minimal performance degradation.
Tech Stack
- TypeScript — Strongly typed backend logic
- Node.js — Event-driven architecture for concurrency
- Redis — Fast in-memory data storage and pub/sub
- Next.js — Frontend interface for visualization (if applicable)
Use Case
This project is ideal for understanding:
- How trading engines work internally
- Order matching algorithms (price-time priority)
- Real-time systems and event streaming
- Performance optimization in backend systems
