Background Reflects Current Candle: The entire chart background changes to green if the current candle is bullish (close > open). It changes to red if the current candle is bearish (close < open).
Solid Background Without Per-Candle Behavior: The background doesn't depend on individual candle colors. It applies one unified color for the entire chart based on the current candle's direction.
Uses a Box to Cover the Chart: Instead of using bgcolor (which applies per candle), this script creates a large invisible rectangle (box) that spans the entire chart area. The box dynamically updates its color with each new candle.
