Hello Dmitry,

Thank you for writing in and welcome to the NinjaTrader Support Forum!

I would like to note that the Stroke class is not expecting a null object. Please take a look at this help guide link for more information about what to pass to a new Stroke object: https://ninjatrader.com/support/help...roke_class.htm

You cannot pass BackBrush to the new Stroke object. This property sets the brush used for painting the chart panel's background color for the current bar.

You'll want to specify a specific brush (ie. Brushes.Blue).

Thanks to your reply.

I understand, that my case is incorrect (I found this case while converting NT7 scripts to NT8), but raise exception is expected. But application is crashed. And my report is about this abnormal action.
