[klaus w]

Hi,
I just got this message:

2021-05-03 14:20:48:507 Gui.Chart.Direct2DForm.RenderBackAll.ERROR: error on rendering background for 'NinjaTrader.NinjaScript.Strategies.KWBBTimeFrames .KWBBTimeFrameV210503' System.NullReferenceException: Object reference not set to an instance of an object.

This comes from core NT. I thought you might be interessted. The chart which the strategy runs on looks wired as you can see in the attachment.
Thanks,

Hi Brandon,
I just send you the requested information. The script is developed by me and I am using the latest version of NT.
Thanks,
