Hello Chris!

Thank you very much for the support.
Any estimations when new update will be released?

Hello,

Thank you for the reply.

There should be an update rolling out early next month or so. I will update this forum post once it is released.

Please let me know if I may be of any further assistance.

Hello,

NinjaTrader 8 R12 was released. This issue has been fixed.

Hello Chris!

Sorry for the long delay with reply. I’ve been testing different ways to ensure proper termination of my indicators, what has taken time. Let me know, if I need to create another thread.

After R12 update, I can see OnWindowDestroy for Control Center window. Thank you. At the same time there is still one issue: Control Center OnWindowDestroy can come at any time: before termination message is sent to all indicators or after it was sent to some. So, if AddOn cleanup is done in OnWindowDestroy (as it is recommended in documentation) and indicators need to use functions from AddOn in their State.Terminated, you can’t be sure that required resources are still exist in AddOn. This makes code much more complicated (corresponding checks, locks etc) and is increasing running time of the code in State.Terminated
Therefore the question:
Can you consider the possibility to send OnWindowDestroy of Control Center window after all other windows are closed or, to be more precise, after State.Terminated is finished in all indicators?


In fact, all my issues are happening because State.Terminated is not always arriving to the indicators as well as to the AddOn (see first post in this thread) . To illustrate this, I’ve modified an example from the first post.
Closing NT8 while attached code is running on 10+ charts will show that State.Terminated is not send to all indicators or, sometimes, even it has arrived, its execution is not finished. Hence another set of questions:
1. Is that a correct behavior of NT8 that State.Terminated is not always arriving to the indicators?
2. Is that a correct behavior of NT8 that State.Terminated is not always finished (I suspect the thread is closed).

Thank you very much in advance

Hello.

Thanks for the follow up.

I am inquiring with our product management team to see if this behavior is expected. I can confirm that the termination state was not complete for an instrument in my testing of your script.

I will reply with my findings shortly.

Hello Chris!

One additional observation.
I am using 3 data connections: Continuum (for futures), FXCM (for forex) and Kinetick (for End of Day).
After loading Test indicator on 15 charts (5 per each data feed) I've disconnected all 3 data feed and have connected them back in few minutes. State.Terminated has been received by only 10 charts.

Not sure if this is important, but better I'll share it.

Thank you
GmA
