Key Features

• Single-Order Matching Engine: The system integrates with a single-order matching engine, ensuring that each order is matched with only one counter-order at a time. This provides efficient and immediate order execution without batch processing.
• Price-Time Priority: The platform ensures fairness by enforcing the price-time priority rule. Orders are matched based on the best price, and if multiple orders have the same price, the system prioritizes the earliest submitted order.
• Limit and Market Order Matching: Users can submit limit and market orders, and the system will automatically match them based on market conditions.
• Real-Time Order Book: The system updates the order book in real time, displaying the market depth with buy and sell prices and volumes.
• Live Market Data: Real-time market data, including order statuses and executed trades, are pushed via WebSocket, keeping users up to date with the latest market movements.
• Historical Trade Records: Users can view all completed trades and access detailed transaction histories.
• High Concurrency Support: The platform is built on a distributed architecture that can handle high volumes of concurrent orders, ensuring stability under heavy traffic.

Technical Stack

• Java/Spring Boot: The core application framework, providing REST APIs and Kafka message handling.
• Kafka: Manages high-concurrency order messages, ensuring reliable processing in the order they were received.
• Redis: Utilizes Redis's ZSet structure for managing the order book, allowing O(log N) insertion and matching of limit orders.
• MySQL: Persists trade data, storing all orders and transaction records for consistency and durability.
• WebSocket: Pushes real-time market and order updates, allowing users to track order progress instantaneously.
• AWS EC2 & ALB: Ensures high availability and auto-scaling capabilities through AWS EC2 and Application Load Balancer (ALB).
