This project bridges that gap by providing a **high-performance backtesting engine**, enabling users to:\n\n- Replay historical market conditions  \n- Evaluate trading strategies  \n- Identify arbitrage opportunities  \n- Track “smart money” (whale behavior)  \n- Optimize execution logic  \n\n---\n\n## 💡 Why This Project Matters\n\nMost traders on prediction markets:\n\n- Lack structured data pipelines  \n- Cannot validate strategies before deploying capital  \n- Depend on intuition instead of data  \n\n👉 This project introduces **data-driven trading for prediction markets**, similar to what exists in traditional finance.\n\n---\n\n## ✨ Key Features\n\n### 📊 Historical Data Engine\n- Fetch and store Polymarket market data\n- Support for:\n  - Order books\n  - Trades\n  - Price history\n  - Liquidity snapshots\n\n### ⚙️ Strategy Backtesting\n- Event-driven simulation engine\n- Tick-level or candle-based replay\n- Plug-and-play strategy interface\n\n### 🧠 Strategy Types Supported\n- Arbitrage strategies\n- Momentum \u002F trend-following\n- Mean reversion\n- Whale tracking (large wallet behavior)\n- Market inefficiency detection\n\n### 🐋 Whale Tracking Module\n- Identify large traders (\"smart money\")\n- Mirror or counter-trade their positions\n- Analyze wallet profitability\n\n### ⚡ Fast Execution\n- Vectorized computation (Python)\n- Optional high-performance execution (TypeScript)\n\n### 📈 Performance Analytics\n- PnL (Profit & Loss)\n- Sharpe ratio\n- Max drawdown\n- Win rate\n- Exposure metrics\n\n---\n\n## 🏗️ Project Structure\n```bash\npolymarket-backtester\u002F\n│\n├── data\u002F # Historical datasets\n├── engine\u002F # Core backtesting engine\n├── strategies\u002F # Strategy implementations\n├── analytics\u002F # Performance metrics\n├── connectors\u002F # API & data ingestion\n├── examples\u002F # Example strategies\n├── tests\u002F # Unit tests\n│\n├── python\u002F # Python implementation\n├── typescript\u002F # TypeScript implementation\n│\n├── docs\u002F # Documentation\n└── README.md\n```\n---\n\n# 🛠 Quick Start\n### 1.
