## Key Research Findings

### Critical Discovery: Universal Fractal Dimension Threshold
- **Threshold of 1.25** identified as universal indicator for market corrections across all asset classes
- Validated across markets, geographies, and time periods
- Provides 2-5 trading days advance warning for regime shifts

### Performance Metrics
- **70-78% regime detection accuracy** with sub-second processing
- **92× GPU speedup** over CPU calculations (NVIDIA RTX 3080 vs Intel i7-10700K)
- **50-85% memory reduction** compared to traditional volatility methods
- **15-20% outperformance** of hedge strategies using the 1.25 threshold

### Technical Implementation Results
- **Real-time processing**: 50-200ms for optimized CPU, 5-20ms with GPU acceleration
- **Memory requirements**: 16-32 GB RAM for real-time calculations
- **Data retention**: 2-3 orders of magnitude less data than Hurst exponent calculation
- **Streaming architecture**: Apache Kafka handling 100,000+ transactions per second

### Regime Classification Thresholds
- **Trending markets**: Fractal dimension 1.0-1.3, Hurst exponent 0.6-0.8
- **Random walk regimes**: Fractal dimension ≈1.5, Hurst exponent ≈0.5
- **Range-bound markets**: Fractal dimension 1.7-2.0, Hurst exponent < 0.5
- **Volatile/crisis regimes**: Fractal dimension > 1.8 with elevated cross-correlations

### Trading Application Recommendations
- **Entry thresholds**: FD < 1.3 for trend following, FD > 1.7 for mean reversion
- **Risk management**: Reduce position size when FD > 1.6, increase when FD < 1.4
- **Stop-loss optimization**: Tighter stops when FD < 1.3, wider stops when FD > 1.7
- **Portfolio construction**: Weight components by inverse fractal dimension

## Integration with SILOQY System

The research provides specific guidance for integrating Hausdorff dimension analysis with the existing SILOQY components:
