Basic strategy script terminated

Why is the output of this

SetDefaults
SetDefaults
Configure
Terminated
Terminated

OnBarUpdate() never gets called.

Hello clabough,

Thanks for your post.

There are essentially 3 instances that generate throughout the process for 3 different situations. All 3 of these cases run its termination throughout its lifetime:

1. The earlier instance used to create the list of indicators by name
   Terminated when you close the indicators window
2. The selected instance which pushes its default settings the UI
   Terminated when you "remove" the indicator from the configured menu, or after the user press OK/Cancels the indicators window
3. The executed instance which runs against the user-configured settings.
   Terminated when the user performs some action which could cause the indicator to remove/reload (or it hits a fatal error

Although, the termination logic executed during these 3 cases should not interfere with another, as long as your resources were properly set up after the state was configured. The first two instances never go beyond State.Defaults and will then be terminated.

You could see in the example below that State.SetDefaults and State.Terminated occur multiple times when adding an indicator and then canceling the indicator dialog.

Adding Indicator, Cancel Indicator Dialog
Right click on Chart -> Select Indicators
Output-> TestStates{d83a7d55-8ff3-4496-b1a1-7a5cbcc95c1e} State=SetDefaults
Add "TestStates" indicator
Output-> TestStates{e633ba70-4341-428b-b622-cace6a7c9a01} State=SetDefaults
Press Cancel
Output-> TestStates{d83a7d55-8ff3-4496-b1a1-7a5cbcc95c1e} State=Terminated
Output-> TestStates{e633ba70-4341-428b-b622-cace6a7c9a01} State=Terminated

Please see this forum post by my colleague Chelsea which details why you may see State.Terminated occur multiple times: https://ninjatrader.com/support/foru...ded#post726288

Also, see this help guide documentation for a visual representation of how each instance goes through its States: https://ninjatrader.com/support/help...fecycle_of.htm
