Panos,
You need another parameter. The last
parameter should be 0 or 1. Look under lineArray in help.
midline=LineArray( startdatetime , StarMidLine , enddatetime , EndMidLine,
1 , 0 ) ;

Subject: [amibroker] LineArray parallel
lines based on study()?
Hi
How to get some more parallel lines with study() ?
I try with LineArray but is something missing here
Few days ago
tomasz provide How to get study line coordinates and based on this example i
wrote the following in this example I would like to draw a line in between the
?RE? and ?SU?
Can any one find my mistake here
midline=LineArray(
startdatetime , StarMidLine , enddatetime , EndMidLine, 1 )
;
the code is :
// How to get more parallel lines
based on study() ?
SetChartBkColor(ParamColor("backround
",colorBlack));
Plot(C, "Price",
colorWhite, styleCandle );
su = Study("SU",
GetChartID() ); isn = IsNull( su );
re = Study("RE", GetChartID()
); isn_re = IsNull( re );
begpoint = NOT isn AND Ref( isn, -1 );
//SU
endpoint = NOT isn AND Ref( isn, 1 ); //
SU
begpointRE = NOT isn_re AND Ref( isn_re, -1 );
//re
endpointRE = NOT isn_re AND Ref( isn_re, 1
); // re
// SU
dt = DateTime();
startdatetime
= LastValue( ValueWhen( begpoint, dt ) );
enddatetime =
LastValue( ValueWhen( endpoint, dt ) );
startval = LastValue( ValueWhen(
begpoint, su ) );
endval = LastValue( ValueWhen( endpoint, su ) );
// RE
dtre = DateTime();
startdatetimeRE = LastValue(
ValueWhen( begpointRE, dtre ) );
enddatetimeRE = LastValue( ValueWhen(
endpointRE, dtre ) );
startvalRE = LastValue( ValueWhen( begpointRE, RE )
);
endvalRE = LastValue( ValueWhen( endpointRE, RE ) );
//
difference RE - SU
StarMidLine=((startvalRE -startval ) /2) +startval
;
EndMidLine=((endvalRE -endval ) /2)+endval ;
Plot( EndMidLine,"",2,1); //
Plot(
StarMidLine,"",3,1);
// what is missing in the following line
midline=LineArray( startdatetime , StarMidLine , enddatetime ,
EndMidLine, 1 ) ;
Plot( midline, "Middle line",
colorBlue );
// Print
Title
if( startdatetime == 0 ) { Title =
"\nStudy with ID=='SU' is not drawn yet"; }
else
if( startdatetimeRE == 0 ) { Title = "Study with
ID=='RE' is not drawn yet"; }
else {
Title =
"StudySU (x0,y0) = " + DateTimeToStr( startdatetime )
+ "," + startval + "\n" +
"StudySU (x1,y1) = " +
DateTimeToStr( enddatetime ) + "," + endval + "\n" +
"StudyrRE (x0,y0) = " + DateTimeToStr( startdatetimeRE ) +
"," + startvalRE + "\n" +
"StudyRE (x1,y1) = " +
DateTimeToStr( enddatetimeRE ) + "," + endvalRE +
"\n StarMidLine
="+StarMidLine+
"\n
EndMidLine="+EndMidLine;
}
////////// code
end
PS : i am trying to make something like gann grids do i have
to use cum() and plot() ?
Thank you again
