About

Liquidity Void highlights candles with very small wicks relative to their body — fast moves that leave unfilled areas price later re-balances.

Upper / lower line plot the candle's high/low for extendBars.
wickPct controls how small the wicks must be (smaller = stricter).
Look for voids that align with FVGs for high-probability fill trades.
