Market Forge

Market Forge is a high-performance, Rust-based matching engine. This project aims to provide a modern, memory-safe, and efficient core for building financial exchanges and trading platforms.

🚀 Why Market Forge?

• ✨ Written in Rust for safety, concurrency, and performance
• 🔁 Efficient limit order book matching logic
• 🧩 Modular and easy to integrate into trading systems
• ♻️ A clean rewrite of the proven Liquibook engine

📦 Features

• Price-time priority matching
• Supports limit, market, and cancel orders
• Unit-tested and performance-optimized core

📚 Example

Order Spec Implementation

use market_forge::{order::OrderSide, order_book::OrderBook, order_spec::OrderSpec};

let mut book = OrderBook::<OrderSpec>::new();

let order = OrderSpec::limit_price(1, OrderSide::Sell, 121, 2);
let result = book.add(&order);

use market_forge::{order::OrderSide, order_book::OrderBook, order_spec::OrderSpec};

let mut book = OrderBook::<OrderSpec>::new();

let order = OrderSpec::market(2, OrderSide::Sell, 5);
let result = book.add(&order);

✅ TODO

• Insert Order
• Cancel Order
• Replace Order
• Recover Order
  • Just use it for recover order price when you missing it
  • It's very slow for high performance matching engine

✅ TODO Order Type

• Market
• Limit
• Immediate-Or-Cancel
• Fill-Or-Kill
• All-Or-None
• Stop Limit
• Stop Market
• Stop-Loss
• Trailing Stop
• OCO
• Post-Only
• Reduce-Only

Order Condition	Crypto Exchanges	Stock Exchanges	Notes
Market	✅ Always	✅ Always	Instant execution
Limit	✅ Always	✅ Always	Goes on order book
Immediate-Or-Cancel	✅ Supported	✅ Supported	For quick partial fills
Fill-Or-Kill	✅ Supported	✅ Supported	For guaranteed full execution
All-Or-None	❓ Rare	✅ Sometimes	Not always supported
Stop / Stop-Loss	✅ Common	✅ Common	Risk management
Trailing Stop	✅ Some platforms	✅ Some brokers	Not in all matching engines
OCO	✅ Often	❌ Rare	More common in crypto
Post-Only	✅ Yes	❌ Rare	Ensures maker-only
Reduce-Only	✅ Derivatives	❌ Rare	Risk protection in leverage
