chart.is_standard

True when the chart type is a standard chart type (candles, bars, line or area). Charts built from synthetic bars do not show the instrument's real open, high, low and close, so a script can use this to warn the reader or to adjust its calculations.

    label.new(bar_index, high, text=chart.is_standard ? "standard chart" : "Another chart type")
