Daily has widest price range, so all intraday prices normalize properly + +2. **Reference Symbol (BTC)**: Uses its own 1s data to compute independent min/max + - BTC and ETH have different price scales + - Independent normalization ensures both are in 0-1 range + +3. **Caching**: Bounds computed once and cached for performance + - Access via `get_normalization_bounds()` and `get_btc_normalization_bounds()` + - Useful for denormalizing model predictions back to actual prices + +#### Usage Examples + +```python +# Get feature vector with normalization (default) +features = base_data.get_feature_vector(normalize=True) +# All OHLCV values are now in 0-1 range + +# Get raw features without normalization +features_raw = base_data.get_feature_vector(normalize=False) +# OHLCV values are in original price/volume units + +# Access normalization bounds for denormalization +bounds = base_data.get_normalization_bounds() +print(f"Price range: {bounds.price_min:.2f} -

Enable `include_candle_ta=True` in `get_feature_vector()` +2. Update model input layer to accept 22,850 features +3. Retrain models with enhanced features +4. Validate improved performance + +**Best For**: Models that benefit from pattern recognition (CNN, Transformer) + +**Pros**: +- Rich pattern information +- Relative sizing context +- No manual feature engineering needed + +**Cons**: +- 3x increase in feature count +- Longer training time +- More memory usage + +#### Strategy 3: Selective TA Features (Balanced Approach) + +**Process**: +1.

Increase `FIXED_FEATURE_SIZE` constant +2. Add new feature extraction logic +3. Retrain all models with new feature size +4. Update model architectures if needed + +**Best For**: Major additions like new data sources, multi-symbol support + +#### Strategy 5: Feature Compression (Advanced) + +**Process**: +1. Use dimensionality reduction (PCA, autoencoders) +2. Compress existing features to make room +3. Add new features in freed space +4.
