BACKGROUNDCOLOR – known bug?

Hi

I came across a potential issue when using BACKGROUNDCOLOR in that it doesn’t behave as I believe it should. I wanted to know if this intended behavior or a known issue.

I have included some sample code to show the problem. If VerticalLines (in the code below/attachment) is set as a configurable variable on this indicator, it does not remove the BACKGROUNDCOLOR by toggling it on/off, whereas toggling DRAWARROW does.

Thanks

Rob

DEFPARAM DRAWONLASTBARONLY = False

// VerticalLines is a boolean, true or false toggle option as a variable for the indicator setting
// Arrows is a boolean, true or false toggle option as a variable for the indicator setting

// Donchian
hh = highest[30](High)
ll = lowest[30](Low)

IF VerticalLines = 1 THEN

// Long signal
IF close = hh THEN
BACKGROUNDCOLOR (10,255,10,50)
ENDIF

// Short signal
IF close = ll THEN
BACKGROUNDCOLOR (255,10,10,50)
ENDIF

ENDIF

IF Arrows = 1 THEN

// Long signal
IF close = hh THEN
DRAWARROW(barindex-1,hh) COLOURED (10,255,10,50)
ENDIF

// Short signal
IF close = ll THEN
DRAWARROW(barindex-1,ll) COLOURED (255,10,10,50)
ENDIF

ENDIF

RETURN
