I've been trying to create an indicator that would draw a candle zone based on its high and low (e.g. AddCloud, but not necessarily).
There would be a criteria to draw it only if such candle had the lowest volume in last X bars.
Ideally if such zone would end at the end of the session (or after specified by me time in options).

I will greatly appreciate if someone is willing to show me how to code it.
I coded some simple indicators, but I haven't figure this one out yet.

Thanks!

input Showplott =yes; def OpenHappened = secondsTillTime(0900) <= 0; def CloseHappened = secondsTillTime(1600) <= 0; def marketOpen = OpenHappened and !CloseHappened; def HighStart= if marketOpen and !marketOpen[1] and (!IsNan(High)) then high else HighStart[1] ; def LowStart = if marketOpen and !marketOpen[1] and (!IsNan(Low)) then low else LowStart[1]; def MarketClosedReturned1= if (Showplott AND MarketOpen, HighStart, double.nan); def MarketClosedReturned2= if (Showplott AND MarketOpen, Lowstart , double.nan); AddCloud(MarketClosedReturned1, MarketClosedReturned2 , Color.white, Color.plum);
