Change band color

[trader2be]

Is it possible to dynamically change the color of certain sections of a band based on a given criterion?, e.g. if MACD > 0 then change band color to green (from that point on, until MACD < 0 and then you change the color to red).

here's a modified builtinmacd (originally provided by Alex)

you can modify the colors of the instantcolorlines in the efs editor.
Hope this helps.

Actually, I couldn't make any of the suggestions work with bands. However I found the following solution, based on drawLineRelative() and it works fine:

if (dblMACD >= 0) strBasisColor = "Color.green"; else strBasisColor = "Color.red";

drawLineRelative(-1,0,0,0, PS_SOLID, 2, eval(strBasisColor),fnGetTagID());
addBand(0,PS_SOLID,2,eval(strBasisColor),"0line");

It basically draws a mini line segment for each bar and creates a band as it goes.
I still have to use the addBand() at the end to create an extension of the band to the rightmost edge of the indicator pane.

are you only trying to change the color of the horizontal bands?

my mistake if that's what you're trying to accomplish. I originally thought you meant the MACD or signal line...

kz - yes that's what I was trying to do, basically change the color of the horizontal band based on the color of the MACD. My solution seems to work but I was wondering if there was a more elegant one. Also what is the purpose of INSTANTCOLORLINE, it seems to have the same way as a regular LINE, what's the difference?

[zeller4]

look at this new version - lines 84-89
you could also look at the signal line if you'd prefer by changing the study lines where appropriate.

the "6" is the width of the band, 0 is the level.

instantcolorline allows the line to change at the peaks and valleys whereas the other normal line changes seems to have a lag on the color change points

if you want them to be a solid color, just change them back
to "PLOTTYPE_LINE"

Thanks for the info. I tried INSTANTCOLORLINE and it works well.
