I am looking for NT8 coding on how to get the result as per the attached image. I want to draw high and low of the engulfing candle where high is higher and low is lower than the open and close of all the subsequent candles. The drawing should remain until a new such engulfing candle comes in the future. To keep the old engulfing candles should be optional. Appreciate any help. Or if you can guide me the approach with some sample coding, I can try.
Thanks.
