range-volatility-based

Investigate range-based volatility dynamics, including compression-expansion cycles in daily price ranges.

Investigate range-based volatility dynamics and compression-expansion cycles in daily price ranges:

• range compression relative to rolling true-range baselines, especially when paired with volume dry-up or stable closes;
• short/long true-range expansion energy that signals transition from quiet to active price discovery;
• true-range acceleration and curvature to identify emerging volatility bursts before they dominate raw volatility;
• signed close-location multiplied by range expansion to distinguish directional range from symmetric noise;
• disagreement between range volatility and close-to-close volatility as evidence of hidden intraday stress or absorption.

Prefer range-volatility measures that describe the geometry of daily uncertainty rather than duplicating close-return volatility.
