Implement automatic trading protection system to prevent excessive losses: PROTECTIONS (100% original code, NOT copied from Freqtrade): - Max Drawdown Protection: Blocks trading when DD > 15% (configurable) - Cooldown Period: 4h mandatory rest after 5% loss - Stoploss Guard: Detects stoploss clusters (>5 per day) - Low Performance Filter: Filters factors with Sharpe < 0.5, Win Rate < 40% ARCHITECTURE: - Base protection interface with common utilities - 4 specialized protection implementations - ProtectionManager orchestrates all active protections - Time-based blocking with automatic expiry TESTS (32 total, ALL PASS): - 25 unit tests in test/backtesting/test_protections.py - 7 integration tests in test/integration/test_all_features.py - Tests cover: normal operation, edge cases, error handling DOCUMENTATION: - Update QWEN.md with development guidelines for AI assistant * Mandatory rules: Update QWEN.md, README, requirements.txt, tests * Pre-commit checklist * Example workflow - Update README.md with protection system features - Update project structure with new modules All code is 100% original - NO license issues with Freqtrade GPLv3.
