Solid Background for Current Candle

What Does This Script Do?

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.
