drawdown-based

Evaluate the depth, duration, and recovery geometry of cumulative losses, emphasizing temporal resilience.

Evaluate depth, duration, and recovery geometry of cumulative losses as measures of temporal resilience:

• rolling peak-to-close drawdown depth scaled by recent volatility, range, or realized path length;
• underwater duration proxies that measure how long price remains below a recent peak without using future recovery dates;
• drawdown acceleration and curvature, distinguishing gradual pullbacks from rapidly worsening selloffs;
• recovery geometry between trough-like lows and current close, including partial rebound strength and close-location quality;
• orderly pullback versus fragile selloff signals using volume panic, range expansion, and downside close concentration.

Prefer drawdown descriptors that quantify resilience and fragility without relying on future troughs or ex-post recovery labels.
