A trading engine is the core of every crypto exchange. It processes buy and sell orders, matches both sides, calculates prices, and ensures that trades execute instantly and accurately. If you want to build a centralized crypto exchange with Spot and Futures markets, your matching engine is the most critical component.

Fenizo develops high-speed trading engines capable of handling large order volumes with low latency, real-time risk checks, and scalable market architecture suitable for professional traders and high-frequency environments.

What Is a Spot & Futures Trading Engine?

A trading engine is a backend system responsible for:

• Order matching
• Orderbook management
• Risk checks
• Balances & margin updates
• Trade settlement
• Market data broadcasting

Spot trading engines handle direct buy/sell orders for assets like BTC/USDT.
Futures trading engines add complexity such as leverage, liquidation, mark price, funding rates and margin calculations.

How a High-Speed Matching Engine Works

The engine continuously processes:

1. Incoming orders via REST or WebSocket
2. Order validation (balance, margin, trading rules)
3. Matching logic using price–time priority
4. Execution with settlement for both sides
5. Orderbook update broadcast in real-time
6. Trade history updates

Matching engines must be extremely fast — often processing thousands of orders per second.

Key Features of a Spot Trading Engine
