Definition

This method is called whenever a new NTWindow is created. It will be called in the thread of that window. This is where you would install your AddOn to an existing window, or if creating your own custom window, add a Menu item to the NinjaTrader Control Center.

Note: This method will also be called on a recompile of the NinjaTrader.Custom project (e.g., when you compile an indicator, strategy, or add-on)

Method Return Value
