Heres another approach (I am working on the high side but it is just
the same if reversed for the Lo).
//P_HigherHiPeriods
NewHi = H > HHV(Ref(H, -1), 250) AND BarIndex() > 250;
Tally = Cum(NewHi);
Plot(Tally,"Tally",1,1);
NH = IIf(Tally > Ref(Tally,-1), BarsSince(Ref(Tally,-2)<Ref(Tally,-
1)),0);
Plot(NH,"BarsSince",5,1|styleOwnScale);
As it is it will give you the start of a series of new highs (it
ignores the rest in the series) and how many bars since the end of
the last series (refer to Plot(NH).
I am pretty certain that a relatively simple variation will give you
the first occurrence of a new high(periods) in the last x number of
days.
