On script remove event

[Dzammer]

Hello!

How to catch OnStrategyRemove event? I use some object that need to be disposed after strategy removed from chart. I tried to use state Terminated but it call after settings window close. The same problem with using standard class destructor (~ClassName).

How can I do this?

Hello Dzammer,

I'm not aware of any property or method that is triggered when a strategy instance (that may already be disabled) is removed from a chart (or the Strategies tab of the Control Center).

I will forward a feature request on your behalf for the Development to consider creating a public method that is triggered when an instance of a strategy is removed (and not just disabled).

However, I'm not quite understanding why OnStateChange when State is State.Terminated is not sufficient for this. This is where it would be recommend to clean up resources.
Can you further describe why this would not work for your goals?

Hi, Chelsea.

I recorded a small video where you can see a problem. http://take.ms/16fRd0

When I add strategy to the chart and push "Ok" button I have this states:
1. SetDefaults
2. Terminated
3. Terminated

So the strategy is added and works but the last state is "Terminated"

Hello Dzammer,

This is expected as some instances created for the Strategies window are terminated.
