This major commit introduces a new advanced trading strategy, resolves critical trading logic errors, and significantly enhances system stability and UI data accuracy.
Key Changes:
- **New Features & Strategies**:
- **Quantum Velocity Strategy**: Added 'quantum_velocity.py', a new hybrid strategy combining a long-term trend filter (EMA 200) with a volatility-based entry trigger (Bollinger Squeeze).
- **Hybrid Pro Backtester**: Added 'lab/backtester_hybrid_pro.py' to facilitate advanced, offline testing and optimization of the QuantumBotX Hybrid strategy.
- **Critical Trading Logic Fixes**:
- Resolved 'Invalid Stops' and 'Unsupported filling mode' errors by refactoring 'core/mt5/trade.py' to use dynamic point calculation and the FOK fill policy.
- Fixed a recurring 'KeyError' in 'BollingerSqueezeStrategy' by ensuring consistent naming for Bollinger Bands columns.
- **System Stability & Robustness**:
- Hardened the graceful shutdown handler in 'app.py' to prevent crashes from repeated Ctrl+C signals, ensuring a clean shutdown process.
- Enhanced the notification system by adding an 'is_notification' flag to logs, allowing for a clear distinction between critical alerts and general activity.
- **Dashboard & UI Enhancements**:
- Fixed the 'Total Bots' card on the dashboard by correcting the backend API ('api_dashboard.py') to send the complete stats payload.
- Replaced static '0' values on dashboard cards with loading spinners for a more professional user experience.
- The 'Create/Edit Bot' modal button now dynamically changes its text to 'Ubah Bot' when in edit mode.
- Update `controller.py` to handle cases where no bots are loaded and to restart active bots.
- Modify `trade.py` to use literal values for filling modes to ensure compatibility with different MT5 library versions.
