CNN Multi-Timeframe Price Vector Enhancements Summary
Overview
Successfully enhanced the CNN model with multi-timeframe price vector predictions and improved training capabilities. The CNN is now the most advanced model in the system with sophisticated price movement prediction capabilities.
Key Enhancements Implemented
1. Multi-Timeframe Price Vector Prediction Heads
- Short-term: 1-5 minutes prediction head (9 layers)
- Mid-term: 5-30 minutes prediction head (9 layers)
- Long-term: 30-120 minutes prediction head (9 layers)
- Each head outputs:
[direction, confidence, magnitude, volatility_risk]
2. Enhanced Forward Pass
- Updated from 5 outputs to 6 outputs
- New return format:
(q_values, extrema_pred, price_direction, features_refined, advanced_pred, multi_timeframe_pred)
- Multi-timeframe tensor shape:
[batch, 12]
(3 timeframes × 4 values each)
3. Inference Record Storage System
- Storage capacity: Up to 50 inference records
- Record structure:
- Timestamp
- Input data (cloned and detached)
- Prediction outputs (all 6 components)
- Metadata (symbol, rewards, actual price changes)
- Automatic pruning: Keeps only the most recent 50 records
4. Enhanced Price Vector Loss Calculation
- Multi-timeframe loss: Separate loss for each timeframe
- Weighted importance: Short-term (1.0), Mid-term (0.8), Long-term (0.6)
- Loss components:
- Direction error (2.0x weight - most important)
- Magnitude error (1.5x weight)
- Confidence calibration error (1.0x weight)
- Time decay factor: Reduces loss impact over time (1 hour decay)
5. Long-Term Training on Stored Records
- Batch training: Processes records in batches of up to 8
- Minimum records: Requires at least 10 records for training
- Gradient clipping: Max norm of 1.0 for stability
- Loss history: Tracks last 100 training losses
6. New Activation Functions
- Direction activation:
Tanh
(-1 to 1 range) - Confidence activation:
Sigmoid
(0 to 1 range) - Magnitude activation:
Sigmoid
(0 to 1 range, will be scaled) - Volatility activation:
Sigmoid
(0 to 1 range)
7. Prediction Processing Methods

: Extracts structured predictions for all timeframes- Backward compatibility: Works with existing orchestrator integration
Technical Implementation Details
Multi-Timeframe Prediction Structure
multi_timeframe_predictions = {
'short_term': {
'direction': float, # -1 to 1
'confidence': float, # 0 to 1
'magnitude': float, # 0 to 1 (scaled to %)
'volatility_risk': float # 0 to 1
},
'mid_term': { ... }, # Same structure
'long_term': { ... } # Same structure
}
Loss Calculation Logic
- Direction Loss: Penalizes wrong direction predictions heavily
- Magnitude Loss: Ensures predicted movement size matches actual
- Confidence Calibration: Confidence should match prediction accuracy
- Time Decay: Recent predictions matter more than old ones
- Timeframe Weighting: Short-term predictions are most important
Integration with Orchestrator
- Price vector system: Compatible with existing
_calculate_price_vector_loss
- Enhanced rewards: Supports fee-aware and confidence-based rewards
- Chart visualization: Ready for price vector line drawing
- Training integration: Works with existing CNN training methods
Benefits for Trading Performance
1. Better Price Movement Prediction
- Multiple timeframes: Captures both immediate and longer-term trends
- Magnitude awareness: Knows not just direction but size of moves
- Volatility risk: Understands market conditions and uncertainty
2. Improved Training Quality
- Long-term memory: Learns from up to 50 past predictions
- Sophisticated loss: Rewards accurate magnitude and direction equally
- Fee awareness: Training considers transaction costs
3. Enhanced Decision Making
- Confidence calibration: Model confidence matches actual accuracy
- Risk assessment: Volatility predictions help with position sizing
- Multi-horizon: Can make both scalping and swing decisions
