liquidity-based

Measure market depth and trading frictions through price impact, turnover variability, and volume-adjusted movement.

Measure trading frictions, price impact, and market-depth conditions from daily OHLCV behavior:

• Amihud-style impact proxies using absolute return or range scaled by dollar-volume or rolling volume baselines;
• absorption patterns where high volume produces small price movement, indicating latent liquidity or supply-demand balance;
• liquidity dry-up signals from shrinking volume, rising range, and deteriorating close location over compatible windows;
• downside impact asymmetry, where negative moves have larger range-per-volume effects than positive moves;
• liquidity recovery or resilience after stress, measured by declining impact and stabilizing close-location behavior.

Prefer impact and absorption measures that remain continuous, scale-normalized, and meaningful across high- and low-volume stocks.
