Hello,
Your code is incorrect.
Usage of Study function is described in the manual:
http://www.amibroker.com/guide/h_studies.html
Correct code is:
Plot(C, "Price", colorBlack, styleCandle );
su = Study("SU", GetChartID() );
isn = IsNull( su );
begpoint = NOT isn AND Ref( isn, -1 );
endpoint = NOT isn AND Ref( isn, 1 );
dt = DateTime();
startdatetime = LastValue( ValueWhen( begpoint, dt ) );
enddatetime = LastValue( ValueWhen( endpoint, dt ) );
startval = LastValue( ValueWhen( begpoint, su ) );
endval = LastValue( ValueWhen( endpoint, su ) );
if( startdatetime == 0 )
{
Title = "Study with ID=='SU' is not drawn yet";
}
else
{
Title =
"Study (x0,y0) = " + DateTimeToStr( startdatetime ) + "," + startval + "\n" +
"Study (x1,y1) = " + DateTimeToStr( enddatetime ) + "," + endval ;
}
Best regards,
