Dave,
Here is an example I use
Y=StochD();
EV1=Cross(Y,30);
S=Sum(Y>Ref(Y,-1),BarsSince(EV1))==BarsSince(EV1);
SumS=S*Sum(S,1+BarsSince(S AND Ref(S,-1)==0));
SumS80=(y>80)*SumS;
Plot(SumS80,"SumS80",colorPink,2);
Plot(SumS,"SumS",colorBlue,2);
for(J=2;J<=12;J=J+2)
{PlotGrid(J,colorIndigo);}
to see the consecutive ascending StochD() bars after a 30 cross
[blue] and, especially, the ones above 80 [pink]
