The project demonstrates excellent architectural design with support for 10+ decentralized exchanges (EdgeX, Backpack, Paradex, Aster, Lighter, GRVT, Extended, Apex, Nado). It implements automated maker/taker trading strategies with hedge mode capabilities for volume generation on perpetual DEX platforms. + +The codebase spans approximately 16,558 lines of Python code, featuring clean separation of concerns through an adapter pattern architecture. Each exchange is implemented as a distinct module inheriting from a common base interface, enabling easy extensibility. The bot supports both standard trading modes and sophisticated hedge trading across multiple venues. + +**Key Highlights:** +- Modular architecture supporting 10+ exchanges +- Async/await implementation for non-blocking operations +- WebSocket integration for real-time order updates +- Comprehensive logging with CSV export and Telegram/Lark notifications +- Dual-mode operation: standard trading and cross-exchange hedging + +**Critical Limitations:** +- No CI/CD pipeline (manual deployment only) +- Minimal test coverage (<1% of codebase) +- No stop-loss mechanism (significant risk) +- No horizontal scaling support +- Security scanning absent + +--- + +## Repository Overview + +- **Primary Language**: Python 3.8-3.12 +- **Framework**: AsyncIO for concurrent operations +- **License**: Non-Commercial License (education/research only) +- **Code Statistics**: + - Total Lines: ~16,558 + - Main Bot: 752 lines (`trading_bot.py`) + - Exchange Modules: ~10,000 lines + - Helper Utilities: ~1,500 lines +- **Community Metrics**: + - GitHub Repository: Active development + - Contributors: Single maintainer + - Documentation: Bilingual (Chinese + English) + +**Technology Stack:** +```python +# Core Dependencies +python-dotenv>=1.0.0 +asyncio==4.0.0 +aiohttp>=3.8.0 +websocket-client>=1.6.0 +pydantic>=1.8.0 +pycryptodome>=3.15.0 + +# Exchange SDKs +bpx-py==2.0.11 # Backpack +lighter-sdk==0.1.4 +x10-python-trading-starknet==0.0.10 # Extended +# + Custom forks for EdgeX and Nado +``` + +--- + +## Architecture & Design Patterns + +### Architecture Pattern + +The repository implements a **Modular Adapter Pattern** with **Factory Pattern** for exchange instantiation.
