colouring bands

[NinjaCustomer]

How do you make those lines that have the space between them filled in with a specific color?

for example, any kind of channel indicator like bollinger bands - colouring in the area between the lines

Hello NinjaCustomer,

Thanks for the note.

Custom rendering using SharpDX would need to be used to solve this. You would be able to get the x and y values for each bar of the plots and iteratively fill the space in between with an Area Brush, sort of like the Region Highlight X drawing tool, but a little more advanced. You can look at the code for that tool in the DrawingTools folder of the NinjaScript editor. The Sample Custom Render indicator is a good tour of how to use SharpDX with NinjaTrader. The code for that indicator can be found in the indicators folder.

Here is the help guide page on using SharpDX:

Please let me know if I may be of any further assistance.

Draw.Region should do the work. But it's slow.
