What is Core.Globals.RandomDispatcher ?

[kevinenergy]

Hi there, I note that in several places in the documentation the code samples use "Core.Globals.RandomDispatcher" e.g:

https://ninjatrader.com/support/helpGuides/nt8/onwindowcreated.htm

I've got some questions:

What is Core.Globals.RandomDispatcher? - aside from the obvious that its some kind of Random dispatcher, can you be more specific?
What kind of Dispatcher is it?
Which pool of dispatchers is it using to choose the random one?
When should I use RandomDispatcher rather than System.Threading.Dispatcher.Current?
when should I use RandomDispatcher rather than ChartControl.Dispatcher / Chart.Dispatcher / ChartTrader.Dispatcher etc?

Thanks,

Kevin.

Hello Kevin,

Thanks for your post.

NinjaTrader spawns as many UI threads (as well as instrument threads) as logical cores.

Core.Globals.RandomDispatcher will select a random (to the user) UI thread.

ChartControl.Dispatcher would use the UI thread associated with that chart window.

You should use a specific dispatcher for when you need to modify something that would reside on that specific thread.

RandomDispatcher would be used for assigning work to an available UI thread.

Let us know if you have any questions.

Thanks for the explanation Jim.
