This Pine v5 code allows you to distinguish between candles on the chart. The body/wick/frame of the "live" candle that hasn't yet closed is colored white. When a live candle is present, the body of the immediately preceding candle is colored green with offset = -1. All other candles remain gray (#2e2e2e). plotcandle fixes the wick/frame so that the live and previous candles are selected when following the trend. If there are other conflicting scripts, the most recently added one quickly takes precedence.
