Range-based realized (historical) volatility estimators over 10/20/30-day windows: close-to-close, Parkinson, Garman-Klass, Rogers-Satchell, and Yang-Zhang. Range estimators use the daily high/low/open/close and are 5–8× more statistically efficient than close-to-close. Alpha tier. Use to measure realized vol robustly, compare estimators, or feed a vol-risk-premium calc.
