Adding DataSeries on running strategy

[GKonheiser]

Hi There

I would like to add a dataSeries to a running strategy. So I want to force the code to go to OnSateChange to enable me to add the additional item.

The problem is that you can not set the State to an earlier state. Is there any work around, ie can I stop and restart the script ?

Thanks

Thank you for your question GKonheiser. The only way to do this that I can think of would be to create a new instance of your Strategy during runtime. While your strategy will not be enabled or running normally, static members will be available, and a DispatcherTimer can be used to drive methods like OnBarUpdate with data series from the host script. I am including publicly available MSDN C# documentation for the DispatcherTimer method.

Note that you can not set the sub-strategy's state directly. I recommend creating an external variable you can set, and setting up your sub-strategies conditional blocks like

public State ExternalState;
protected override void OnStateChange()
{
    if (State == State.Configure || ExternalState == State.Configure)
    {
        // ...
    }
}[/FONT]
