How do I change the bar color in a custom bar type

[wjadevries]

I created a custom bar type based on the original RenkoBars type, where I show the wicks.
That's working fine, but now I want to change the bar color based on some conditions.
In the OnDataPoint override I'm trying to do that with BarBrush or BarBrushes[0], but I get a compile error stating "The name BarBrush does not exist in the current context".
How can I achieve it?

Hello wjadevries,

Thank you for your post.

OnDataPoint is used to define how the bar is built. The OnDataPoint() method is where you should adjust data points (bar values) of your series.

BarBrush is specific to indicators and strategies. To present bars information in a different visual representation, you could color the bars within an Indicator or by using ChartStyles. When using ChartStyles, the DownBrush and UpBrush can be used to set the color of the bar from the chart style.

Please see the following help guide links about working with custom Brushes and using ChartStyles.

If I understand correctly I can't use chartsyles in a script to set bar colors individually based on a condition?
So I need to create a separate indicator for it?

Hello wjadevries,

Thank you for your note.

BarBrush can be used in a Strategy or an Indicator to change the color of a bar. Please note that this cannot be set in a BarsType.

ChartStyles can also be used to change the color of a bar when modifying UpBrush or DownBrush properties of the ChartStyle.

Please see the attached example strategy, ChangeBarColors, for how BarBrush, UpBrush, and DownBrush may be used.

Thanks for your explanation.
Already created an indicator for it and that works fine.
Cheers!
