Backgrounds

bgcolor() tints the background of each bar. It is the right tool for visualising sessions, filter windows, or regime labels — any colour-only, per-bar state.

barcolor() recolours the chart's candles themselves. The host repaints the body and wick in the colour you supply; na leaves the candle in its default colour.

Two declarative calls render *synthetic candles* from your own OHLC series:

Tables

A table is a floating UI element pinned to one of the chart's nine positions. It is the right tool for always-visible, grid-shaped summaries (strategy report, regime read-out, session…
