Volume Color Bars

[Rxxar]

Hi Everyone,

I'm trying to develop an Indicator that Plots Volume but changes color at certain Level same with the bars.



The thing is that I have cut bits of code from here and there and I would like to make it work right. Its actually working (I don't know how ) but I cant change the color as wish. So maybe someone can help me to find out what I am doing wrong in the code ( Im newbie) .

Hello Rxxar,

Thank you for your post.

Are you trying to change the bar color, or the plot color?

BarBrush will change the color of the bar.
PlotBrushes will change the color of the plot.

It also looks like you have the same exact condition for the color change logic. If you want the color to change, you'll need to have different conditions for the color change logic.

Please let us know if you have any further questions.
