# Enhanced DQN and Leverage Integration Summary
|
||||
|
||||
## Overview
|
||||
Successfully integrated best features from EnhancedDQNAgent into the main DQNAgent and implemented comprehensive 50x leverage support throughout the trading system for amplified reward sensitivity.
|
||||
|
||||
## Key Enhancements Implemented
|
||||
|
||||
### 1. **Enhanced DQN Agent Features Integration** (`NN/models/dqn_agent.py`)
|
||||
|
||||
#### **Market Regime Adaptation**
|
||||
- **Market Regime Weights**: Adaptive confidence based on market conditions
|
||||
- Trending markets: 1.2x confidence multiplier
|
||||
- Ranging markets: 0.8x confidence multiplier
|
||||
- Volatile markets: 0.6x confidence multiplier
|
||||
- **New Method**: `act_with_confidence()` for regime-aware decision making
|
||||
|
||||
#### **Advanced Replay Mechanisms**
|
||||
- **Prioritized Experience Replay**: Enhanced memory management
|
||||
- Alpha: 0.6 (priority exponent)
|
||||
- Beta: 0.4 (importance sampling)
|
||||
- Beta increment: 0.001 per step
|
||||
- **Double DQN Support**: Improved Q-value estimation
|
||||
- **Dueling Network Architecture**: Value and advantage head separation
|
||||
|
||||
#### **Enhanced Position Management**
|
||||
- **Intelligent Entry/Exit Thresholds**:
|
||||
- Entry confidence threshold: 0.7 (high bar for new positions)
|
||||
- Exit confidence threshold: 0.3 (lower bar for closing)
|
||||
- Uncertainty threshold: 0.1 (neutral zone)
|
||||
- **Market Context Integration**: Price and regime-aware decision making
|
||||
|
||||
### 2. **Comprehensive Leverage Integration**
|
||||
|
||||
#### **Dynamic Leverage Slider** (`web/dashboard.py`)
|
||||
- **Range**: 1x to 100x leverage with 1x increments
|
||||
- **Real-time Adjustment**: Instant leverage changes via slider
|
||||
- **Risk Assessment Display**:
|
||||
- Low Risk (1x-5x): Green badge
|
||||
- Medium Risk (6x-25x): Yellow badge
|
||||
- High Risk (26x-50x): Red badge
|
||||
- Extreme Risk (51x-100x): Red badge
|
||||
- **Visual Indicators**: Clear marks at 1x, 10x, 25x, 50x, 75x, 100x
|
||||
|
||||
#### **Leveraged PnL Calculations**
|
||||
- **New Helper Function**: `_calculate_leveraged_pnl_and_fees()`
|
||||
- **Amplified Profits/Losses**: All PnL calculations multiplied by leverage
|
||||
- **Enhanced Fee Structure**: Position value × leverage × fee rate
|
||||
- **Real-time Updates**: Unrealized PnL reflects current leverage setting
|
||||
|
||||
#### **Fee Calculations with Leverage**
|
||||
- **Opening Positions**: `fee = price × size × fee_rate × leverage`
|
||||
- **Closing Positions**: Leverage affects both PnL and exit fees
|
||||
- **Comprehensive Tracking**: All fee calculations include leverage impact
|
||||
|
||||
### 3. **Reward Sensitivity Improvements**
|
||||
|
||||
#### **Amplified Training Signals**
|
||||
- **50x Leverage Default**: Small 0.1% price moves = 5% portfolio impact
|
||||
- **Enhanced Learning**: Models can now learn from micro-movements
|
||||
- **Realistic Risk/Reward**: Proper leverage trading simulation
|
||||
|
||||
#### **Example Impact**:
|
||||
```
|
||||
Without Leverage: 0.1% price move = $10 profit (weak signal)
|
||||
With 50x Leverage: 0.1% price move = $500 profit (strong signal)
|
||||
```
|
||||
|
||||
### 4. **Technical Implementation Details**
|
||||
|
||||
#### **Code Integration Points**
|
||||
- **Dashboard**: Leverage slider UI component with real-time feedback
|
||||
- **PnL Engine**: All profit/loss calculations leverage-aware
|
||||
- **DQN Agent**: Market regime adaptation and enhanced replay
|
||||
- **Fee System**: Comprehensive leverage-adjusted fee calculations
|
||||
|
||||
#### **Error Handling & Robustness**
|
||||
- **Syntax Error Fixes**: Resolved escaped quote issues
|
||||
- **Encoding Support**: UTF-8 file handling for Windows compatibility
|
||||
- **Fallback Systems**: Graceful degradation on errors
|
||||
|
||||
