Overview
Bars from 04:00 to 09:30 use the pre-market color, 09:30 to 16:00 use the regular-session color, and 16:00 to 20:00 use the post-market color. Three color inputs change those fills. Backgrounds appear only when the chart is 30 minutes or shorter; on higher timeframes a bottom-right message appears and the background stays uncolored. It does not generate trade signals.
- Pre-market, regular, and post-market background colors
- Three user-selectable session colors
- Draws only on charts of 30 minutes or less
- Bottom-right warning when the timeframe is too high

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
