re: Get Bar Color

[saturntd]

Hello,
How can I get the bar color for the last bar plotted?
I have a vendor indicator that plots the last bar a certain color when a condition is triggered.
The vendor is unwilling to make the condition info available in a script.
I would like to access the color of last bar plotted in my own script to decide if I want to take action.

Hello saturntd,

Thank you for your post.

You could try checking the Indicator.BarBrushes collection for the color of the bar x bars ago, however we recommend using the same logic the indicator does.

BarBrushes - https://ninjatrader.com/support/help...barbrushes.htm

You could use a condition for determining the previous bar's color. If previous close greater than previous open then the bar was green. If previous close less than previous open then the bar was red.

Please let me know if you have any other questions.

Thanks for responding Gaby.
Unfortunately, BarBrushes[0] doesn't show any colors.
If I check like this: if(BarBrushes[0] == Brushes.Yellow) ...
It never finds the color I'm looking for.
I even tried looping back 10 bars for each new bar & it doesn't find anything either.
Is there some other way to get the bar colors?

I think what I would do, if I were you, is to get the COLOR of the bar brush e.g. Color myColor = ((SolidColorBrush)myIndicator.BarBrushes[0]).Color. Then, add a plot or print statement to dump the RGB values of myColor e.g. Print(myColor.R + " " + myColor.G + " " + myColor.B); and that should give you an idea how to proceed. The values will either be there or they will not be there. If they are there, you'll know what to compare with. It could be that the brush INSTANCES are not equal because they're cloned, or they differ in opacity/alpha, or whatever, but the color is what it is. Let us know if this approach yields you the data you are looking for. It could also be that the vendor has hidden this information and is not really using BarBrushes even though it looks like they are - they could be painting the bars themselves in OnRender from a private series.

Hello,

QuantKey_Bruce has provided some good information. I agree with the approach he is recommending since you don't have access to the logic that the other indicator is using to change the bar color.

Thanks Bruce & Gaby.
Still couldn't get it to work.
Not going to worry about it anymore.
