I found such an indicator on Pine Script on the Internet. I have a question: this indicator is recalculated every time the candle is updated (that is, when the candle has not yet formed) is it possible to do something so that the indicator is recalculated only when the candle has formed? I ask for help in this matter, since I myself do not know Pine Script very well
