Hi,

Std Error Channel Power using Pivots Plus

Could you please help me to modify  the formula below for the

Second or previous  "Instances  "of the  Pivot Point  

say i2 = 2  or  previous occurrence of the Pivot

i2:= Input("Instance", 0, 10, 2);

Thank you in advance,

Derek

*code*

i1:=Input("Pivot ( 1=Minor 2= Interim 3=Major 4=Primary )", -4, 4, -3);
i2:= Input("Instance", 0, 10, 1);

{ie  Line Below }

Periods:=LastValue( (ValueWhen(i2,ExtFml("PowerPivots.Pivots")=i1,LastValue(
BarsSince(ExtFml("PowerPivots.Pivots")=i1)))));

nd:= Input("number of deviations",0,10,2);
end:=LastValue(Cum(1));
pt:=LastValue(LinearReg(C,Periods));
slope:=LastValue(LinRegSlope(C,Periods));
start:=BarsSince(Cum(1)>=end-(Periods-0));
center:=If(start=0,pt - (slope*(end-Cum(1))),0);
dis:=nd*LastValue(STE( C, Periods));
center+dis;
center;
center-dis
