PaintBar Problems...

May 15th, 2019, 02:08 AM

Hi,

I am currently trying to learn Tradestation's EasyLanguage and have come across an error ("this plot has been defined using a different name") that I cannot resolve no matter what I try...

Code

inputs:
priceC( close ) ,
priceL( low )
VTperiod( 22 ) ;

variables:
VT ( 0 ) ,
ColorToUse ( 0 ) ;

VT = ( ( Highest ( priceC, VTperiod ) - priceL ) / ( Highest ( priceC, VTperiod ) ) * 100 ) ;
Plot1(  VT, !( "VT" ), RGB ( 0, 128, 0 ), Default, 5  ) ;

if VT = 0 then
	ColorToUse = Yellow ;
	
PlotPaintBar( High, Low, Open, Close, "VT" , ColorToUse ) ;

Thanks in advance

netarchitech,

PlotPaintBar will automatically receive Plot1 to Plot4 (or to Plot2 in case you only specify two parameters for BarHigh, BarLow, BarOpen, BarClose). This results in your code using Plot1 twice and the easiest fix would be to use a different plot number for your current Plot1 (for example Plot5).

Hi ABCTG,

Thank you for your reply. I really appreciate your assistance...

I incorporated the changes you specified and it did solve the issue. The code compiled successfully. Unfortunately, the study paints all the bars yellow instead of just the bars where VT = 0...

Code

inputs:
priceC( close ) ,
priceL( low )
VTperiod( 22 ) ;

variables:
VT ( 0 ) ,
ColorToUse ( 0 ) ;

VT = ( ( Highest ( priceC, VTperiod ) - priceL ) / ( Highest ( priceC, VTperiod ) ) * 100 ) ;
Plot5(  VT, !( "VT" ), RGB ( 0, 128, 0 ), Default, 5  ) ;

if VT = 0 then
	ColorToUse = Yellow ;
	
PlotPaintBar( High, Low, Open, Close, "VT" , ColorToUse ) ;

Any thoughts?

Thanks again

netarchitech,

you are welcome. Your code doesn't use any alternative colors and once "VT = 0" is fulfilled the variable ColorToUse will be set to yellow and as you use this for the bar colors all future bars will be yellow.
Depending on your preferences you could for example change the value in ColorToUse to an alternative color in case VT is different than 0.

netarchitech,

another approach could be to include the paint bar plotting within your condition to only plot the bars that match your criteria.

Code

if VT = 0 then
begin
	ColorToUse = Yellow ;
	PlotPaintBar( High, Low, Open, Close, "VT" , ColorToUse ) ;
End 
else //unpaint the bar if the criteria is no longer true
begin
	NoPlot( 1 ) ; 
	NoPlot( 2 ) ;
	NoPlot( 3 ) ;
	NoPlot( 4 ) ;
end ;
