Advanced Zone Analysis Features - Deep Dive (v2.1)

v2.1 UPDATE (2025-10-22):
This notebook demonstrates ADVANCED features of BQuant v2.1 zone analysis:

1. Time metrics - peak_time_ratio, trough_time_ratio
2. Swing strategies - FindPeaks, PivotPoints comparison
3. Divergence detection - classic divergence patterns
4. Volatility analysis - combined volatility metrics
5. Volume analysis - volume-indicator correlation
6. Hypothesis tests - statistical validation (all tests via pipeline)
7. Regression analysis - predictive modeling (optional)
8. Validation suite - robustness testing (optional)

KEY v2.1 FEATURES:
- Universal API: .with_strategies(swing='find_peaks', divergence='classic', ...)
- Automatic features: zone.features populated by .analyze()
- Pipeline integration: run_hypothesis=True, run_regression=True
- Migration guide: Old API (MACDZoneAnalyzer) -> New API (analyze_zones)

USAGE:
python research/notebooks/03_analysis_new_features.py --no-trap

See also:
- research/notebooks/03_zones_universal.py - basic universal usage
- examples/02a_universal_zones.py - multi-indicator examples
