Overview

Liquidity Hunter | AlphaScript detects wick breaks or retests that sweep through swing levels using ATR-based wick filtering. Bullish and bearish sweeps are labeled and colored on the chart. Active swing levels are displayed as dotted lines. The script supports both wick and retest sweep modes with configurable maximum levels, age, and visible sweeps.
