Here is an example of finding the values for the left and right ends
of 2 lines, with studyID "F1" & "F2". This is fairly old one I dug up
in particular this draws lines according to fib ratios of the distance
between the 2 lines. No idea why i did this now.
But it will give you one method, albeit old, of working with lines.
Plot(C,"",colorBlack,styleBar);
Upper=ValueWhen(NOT IsNull( Study("f1",GetChartID())
),Study("f1",GetChartID()));
Lower=ValueWhen(NOT IsNull( Study("f2",GetChartID())),Study("f2",GetChartID()));
TLB = ValueWhen( Upper AND IsNull(Ref(Upper,-1)), BarIndex());
TLP = ValueWhen( Upper AND IsNull(Ref(Upper,-1)), Upper );
TRB = ValueWhen( Upper ==LastValue(Upper), BarIndex());
TRP = ValueWhen( Upper ==LastValue(Upper), Upper );
BLB = ValueWhen( Lower AND IsNull(Ref(Lower,-1)), BarIndex());
BLP = ValueWhen( Lower AND IsNull(Ref(Lower,-1)), Lower );
BRB = ValueWhen( Lower ==LastValue(Lower), BarIndex());
BRP = ValueWhen( Lower ==LastValue(Lower), Lower );
procedure FibLine(x,y)
{
LB = LastValue( BLB+(TLB-BLB)*x );
RB = LastValue( BRB+(TRB-BRB)*x );
LP = LastValue( BLP+(TLP-BLP)*x );
RP = LastValue( BRP+(TRP-BRP)*x );
Line = LineArray( LB, LP, RB, RP ,0 );
Plot( Line, "Line "+(x*100)+"%", y, styleLine);
}
FibLine(0.5,colorRed);
FibLine(0.618,colorBlue);
FibLine(0.382,colorGreen);
FibLine(1.618,colorRed);
FibLine(-0.618,colorRed);
