There's a function called BarsSince.
Hope this helps
JOE L.
// To demonstrate use of BarsSince and SelectedValue..
SignalArray = Cross(MA(C,10),MA(C,20));
if( SelectedValue(BarsSince(SignalArray)< 10));
{
// your work
a = 30;
}
A = SelectedValue(BarsSince(SignalArray));
Plot(C,"Close",colorBlack,styleThick);
Plot(MA(C,20),"20MA",colorBlue,styleLine);
Plot(MA(C,10),"10MA",colorGreen,styleLine);
Title = "Crossing Point = " + WriteVal(Signalarray,8.3) + " Bars Since Crossing
Point =" + WriteVal(A);
