crash-warning

Identify early warning signals of market collapses by tracking volatility compression, liquidity depletion, and structural fragility patterns.

Search for early warning signals of structural fragility before abrupt downside moves:

• volatility compression that breaks into range expansion while price closes weakly, suggesting air-pocket risk;
• failed rebound structures after large down days, especially when volume remains elevated and close location deteriorates;
• support-break pressure measured by gap direction, intraday body, range expansion, and rolling downside persistence;
• liquidity depletion proxies, such as rising range-per-volume impact or abnormal volume with limited upward progress;
• crowding unwind risk from extended directional agreement followed by opposite shadows or negative volume-confirmed moves.

Design continuous crash-warning factors that capture pre-crash fragility while avoiding binary event labels or look-ahead outcomes.
