Fw: [amibroker] How to express some conditin occurred in the last ten bars

["Joe Landry" <jelandry@xxxxxxxxxxxxx>]

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);
