Dear Jose,
Op:=ValueWhen(1,signal,O);
would return the Open when signal is true ie. of the last bar of the
PREVIOUS period.
[If plotted, it looks correct because the segmentation is right but
actual bar count from start is (-1) ].
[Assumed that bar 1 is the beginning of data set].
And,
Cl:=ValueWhen(1,signal,Ref(C,-1));
would be the (close - 1bar) ie. of the previous (of PREVIOUS)
period.
???
1)The signal should start +1bar after being true.
2) Cl: should be forward referenced.
So,
signal:=Mod(Ref(Cum(1),-1),pds)=0;
Cl:=ValueWhen(1,signal,Ref(C,pds-1));
From,
humble
