🛠️ Quick Start

C++ (Recommended for Production)

cd cpp-single-exchange
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc)
./market_maker

Rust

cd rust-single-exchange
cargo build --release
cargo run --release

Python

cd python-single-exchange
pip install -e .
python -m src.main

⚙️ Configuration

All implementations support configuration via:

• Environment variables for API credentials
• JSON config files for strategy parameters

Example environment setup:

export BINANCE_API_KEY="your_key"
export BINANCE_API_SECRET="your_secret"
export BYBIT_API_KEY="your_key"
export BYBIT_API_SECRET="your_secret"

📈 Trading Strategies

Basic Market Making

• Quote bid/ask around fair value (mid-price)
• Fixed spread with configurable parameters
• Simple position limits

Inventory-Adjusted Market Making

• Skew quotes based on current inventory
• Reduces position when inventory is high
• More aggressive pricing to unload inventory

Avellaneda-Stoikov Model

• Optimal market making under inventory risk
• Reservation price based on inventory and risk aversion
• Volatility-aware spread calculation
• Time-decay adjustments

🔒 Risk Management

All implementations include:

• Position Limits: Maximum position size per symbol
• Order Limits: Size, value, and rate limits
• Loss Limits: Per-trade, daily, and drawdown limits
• Kill Switch: Automatic trading halt on breaches
• Price Deviation: Reject orders far from mid-price

📝 Key Components

Order Book

• L2/L3 order book representation
• Efficient updates (O(log n) for sorted structures)
• Spread and mid-price calculations

Exchange Connectors

• WebSocket for real-time market data
• REST API for order management
• HMAC-SHA256 request signing
• Rate limiting and error handling

Strategy Engine

• Event-driven architecture
• Configurable parameters
• Signal integration (optional)

🎯 Which Implementation to Choose?
