detect indicator removed or deactivated

[1001111]

Hello,

if I have installed an indicator (any),
the following statuses are run through in the OnStateChange() method.

OnStateChange() State: Terminated
OnStateChange() State: Configure
OnStateChange() State: DataLoaded
OnStateChange() State: Historical
OnStateChange() State: Transition
OnStateChange() State: Realtime


How can you tell if an indicator has been deactivated or removed from the chart?

(I want to take certain actions when an indicator has been disabled or removed.)

Hello 1001111,

Thank you for the post.

The State.Terminated would be how to tell that. Terminated can be called multiple times and for multiple different instances so depending on what you need to clean up you may need to also add logic to determine if the script actually started.

Can you provide some detail about what you are trying to do when the script is disabled?

A simple way to know the script started so you can know the next Terminated is actually when the script is being stopped would be to use a bool:

private bool myBool; 

and then in OnStateChange: 

if(State == State.Historical)
{
    myBool = true; 
} else if(State ==State.Terminated)
{
    if(myBool == true)
    { 
         // we can safely assume the script was actually started because it hit state.historical
     }
}

I look forward to being of further assistance.

The indicator collects data during the term. But I have to delete it if it is deactivated or deleted.


I'll try what you wrote. Thanks a lot
