Below is an alternative way to calculate this line. This method
gives us a continous array that can be used in further calculations
( just remember that it looks into the future, similar to a Zig
line).

SetBarsRequired(1000,1000);
z=x0=x1=y0=y1=Null;
Cond=Cross(StochD(),70);// the condition
for(i=0;i<BarCount;i++)
{
if(Cond[i])
{
x0=x1; y0=y1; x1=i; y1=H[i];
s=LineArray(x0,y0,x1,y1);
for(j=x0;j<=x1;j++) z[j]=s[j];
}
}
Plot(C,"",colorDefault,styleCandle);
Plot(z,"",colorGreen,styleLine);
