Low Volume Engulfing

This Pine Script (version 6) defines a trading indicator called "Low Volume Engulfing" (LVE) that runs on the price chart (overlay = true). It detects bullish and bearish engulfing patterns with a volume filter, where the current candle’s volume must be lower than the previous candle by a user-defined threshold. Key features include:

Volume-based engulfing detection with a configurable threshold.
Engulfing tolerance to allow slight misalignment in high/low ranges.
Optional P&L visualization: draws entry, stop loss, take profit lines, and colored boxes over a defined length.
Customizable visuals: signal colors, risk/reward ratio, and visualization length.
Alerts for bullish and bearish LVE signals.
