## 🛠️ Installation
### Production Installation
```bash
# Install with pipx (recommended)
pipx install bitfinex-maker-kit
# Configure API credentials
echo 'BITFINEX_API_KEY=your_api_key_here' > .env
echo 'BITFINEX_API_SECRET=your_api_secret_here' >> .env
```
### Development Installation
**Recommended: One-Command Setup** (solves externally-managed-environment errors)
```bash
# Clone repository
git clone https://github.com/0xferit/bitfinex-maker-kit.git
cd bitfinex-maker-kit
# One-command setup (creates venv + installs everything)
make setup
# Activate virtual environment (if not already active)
source venv/bin/activate # On Windows: venv\Scripts\activate
# Verify installation
make quality # Run all quality checks
pytest # Run tests
```
**Alternative: Using pipx** (for tool installation)
```bash
# Install as isolated application
pipx install git+https://github.com/0xferit/bitfinex-maker-kit.git
# For development
git clone https://github.com/0xferit/bitfinex-maker-kit.git
cd bitfinex-maker-kit
pipx install -e .
```
**Manual Installation** (if virtual environment setup fails)
```bash
# Option 1: Force install (not recommended)
pip install -e ".[dev]" --break-system-packages
# Option 2: User install
pip install -e ".[dev]" --user
# Option 3: Traditional virtual environment
python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
pre-commit install
```
**💡 Troubleshooting "externally-managed-environment" Error:**
- **Modern Python/macOS**: Use virtual environment (recommended above)
- **System Python**: Use `pipx` for isolated installation
- **Docker**: Use the provided Dockerfile for containerized development

### Key Design Patterns
- **Dependency Injection**: Clean service boundaries with container pattern
- **Command Pattern**: Extensible command system with undo capabilities

- **Facade Pattern**: Simplified interfaces over complex subsystems
- **Domain-Driven Design**: Rich domain objects with business logic
## ⚠️ Risk Disclaimer
**IMPORTANT**: Trading cryptocurrency involves substantial risk of loss and is not suitable for every investor. The volatile nature of cryptocurrency markets may result in significant financial losses. You should carefully consider whether trading is suitable for you in light of your circumstances, knowledge, and financial resources.
- **Test First**: Always use `--dry-run` mode before live trading
- **Start Small**: Begin with minimal position sizes
- **Monitor Closely**: Actively supervise automated strategies
- **Risk Management**: Never trade more than you can afford to lose

Rate**: Success/failure ratio\n- **CPU Usage**: Process CPU percent\n- **Memory Usage**: RSS/MB\n\n## \ud83e\udd1d Contributing\n\n### Development Setup\n```bash\n# Install development dependencies\npip install -e \".[dev,test,security]\"\n\n# Install pre-commit hooks\npre-commit install\n\n# Run full test suite\ntox\n```\n\n### Code Standards\n- **Python 3.12+** required\n- **Type hints** mandatory\n- **100% test coverage** for new features\n- **Security review** for all changes\n- **Performance benchmarks** for optimizations\n\n### Pull Request Process\n1. Fork the repository\n2. Create feature branch: `git checkout -b feature/amazing-feature`\n3. Make changes with tests and documentation\n4. Run quality checks: `tox`\n5. Submit pull request with detailed description\n\n## \ud83d\udcd6 Codebase Structure\n\n### Directory Organization\n```\nbitfinex_maker_kit/\n\u251c\u2500\u2500 __init__.py # Package entry point and exports\n\u251c\u2500\u2500 cli/ # CLI interface (argument parsing and routing)\n\u251c\u2500\u2500 cli/ # CLI-specific components\n\u2502 \u251c\u2500\u2500 argument_parser.py # Command-line argument parsing\n\u2502 \u2514\u2500\u2500 command_router.py # Command routing logic\n\u251c\u2500\u2500 commands/ # Individual command implementations\n\u2502 \u251c\u2500\u2500 core/ # Command abstractions and patterns\n\u2502 \u2502 \u251c\u2500\u2500 base_command.py # Base command interface\n\u2502 \u2502 \u251c\u2500\u2500 command_executor.py # Command execution framework\n\u2502 \u2502 \u251c\u2500\u2500 command_result.py # Result handling\n\u2502 \u2502 \u2514\u2500\u2500 [specialized_commands] # Command implementations\n\u2502 \u2514\u2500\u2500 [individual_commands].py # Main CLI commands\n\u251c\u2500\u2500 core/ # Core business logic\n\u2502 \u251c\u2500\u2500 api_client.py # Clean Bitfinex API wrapper\n\u2502 \u251c\u2500\u2500 order_update_service.py # Deprecated shim; use TradingService.update_order\n\u2502 \u251c\u2500\u2500 order_manager.py # Order lifecycle management\n\u2502 \u2514\u2500\u2500 order_validator.py # Multi-layer validation\n\u251c\u2500\u2500 domain/ # Domain objects and business rules\n\u2502 \u251c\u2500\u2500 order_id.py # Order identification value object\n\u2502 \u251c\u2500\u2500 price.py # Price value object with validation\n\u2502 \u251c\u2500\u2500 amount.py # Amount value object with validation\n\u2502 \u2514\u2500\u2500 symbol.py # Trading pair symbol validation\n\u251c\u2500\u2500 services/ # Service layer with dependency injection\n\u2502 \u251c\u2500\u2500 container.py # Dependency injection container\n\u2502 \u251c\u2500\u2500 trading_service.py # Core trading operations\n\u2502 \u251c\u2500\u2500 cache_service.py # (removed) no caching in trading paths\n\u2502 \u2514\u2500\u2500 performance_monitor.py # Real-time metrics collection\n\u251c\u2500\u2500 strategies/ # Trading strategy implementations\n\u2502 \u2514\u2500\u2500 order_generator.py # Flexible order generation\n\u251c\u2500\u2500 update_strategies/ # (deprecated)\n\u2502 \u2514\u2500\u2500 cancel_recreate_strategy.py # Cancel-recreate fallback\n\u251c\u2500\u2500 websocket/ # WebSocket integration\n\u2502 \u251c\u2500\u2500 connection_manager.py # Connection lifecycle\n\u2502 \u2514\u2500\u2500 event_handler.py # Real-time event processing\n\u251c\u2500\u2500 ui/ # User interface components\n\u2502 \u2514\u2500\u2500 market_maker_console.py # Interactive trading console\n\u251c\u2500\u2500 config/ # Configuration management\n\u2502 \u251c\u2500\u2500 environment.py # Environment-aware configuration\n\u2502 \u2514\u2500\u2500 trading_config.py # Trading-specific settings\n\u2514\u2500\u2500 utilities/ # Shared utilities and helpers\n \u251c\u2500\u2500 [various_utilities].py # Helper functions and utilities\n \u251c\u2500\u2500 performance_dashboard.py # Performance visualization\n \u2514\u2500\u2500 profiler.py # Performance profiling tools\n```\n\n### Key Design Patterns\n- **Dependency Injection**: Clean service boundaries with container pattern\n- **Command Pattern**: Extensible command system with undo capabilities \n- **Strategy Pattern**: Pluggable algorithms for order generation and updates\n- **Facade Pattern**: Simplified interfaces over complex subsystems\n- **Domain-Driven Design**: Rich domain objects with business logic\n\n## \u26a0\ufe0f Risk Disclaimer\n\n**IMPORTANT**: Trading cryptocurrency involves substantial risk of loss and is not suitable for every investor. The volatile nature of cryptocurrency markets may result in significant financial losses. You should carefully consider whether trading is suitable for you in light of your circumstances, knowledge, and financial resources.\n\n- **Test First**: Always use `--dry-run` mode before live trading\n- **Start Small**: Begin with minimal position sizes\n- **Monitor Closely**: Actively supervise automated strategies\n- **Risk Management**: Never trade more than you can afford to lose\n\n## \ud83d\udcc4 License\n\nThis project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details.\n\n### Third-Party Dependencies\nAll dependencies use compatible permissive licenses (MIT, BSD, Apache-2.0).
