Strategy State

[fxRichard]

Hey Jessica,

Can't get this code to run properly:

ExampleStateStrategy Snippet:

......
    else if (State == State.Configure)
    {
	AddChartIndicator(ExampleStateIndicator());
    }
}

protected override void OnBarUpdate()
{
	double  data = ExampleStateIndicator()[0];
	Print("STRATEGY - " + State);
}

ExampleStateIndicator Snippet:

protected override void OnBarUpdate()
{
	Value[0] = 0;
	Print("INDICATOR - " + State);
}

The output in the window gives the following error:

Strategy 'ExampleStateStrategy': Error on calling 'OnBarUpdate' method on bar 0: Index was outside the bounds of the array.

This tells me the indicator has not yet run so if we add the following line to the strategy code:

if(State < State.Realtime)
	return;

We then get this error once the first realtime bar closes:

Strategy 'ExampleStateStrategy': Error on calling 'OnBarUpdate' method on bar 6997: Index was outside the bounds of the array.

I have tried several variations and have gotten none of them to work.

Do you have a working example of this scenario working correctly?

I do in fact have a pair which will process realtime correctly. I am attaching it to this reply. Please let us know if there are any other ways we can help.

Thanks Jessica, I'll take a look at this. I really appreciate your help.

Just a side note, this could be explained better in the documentation or handled in a better way without having to keep a reference in the scope of the function only when the state is less than Realtime.

Just a thought, have a great weekend!
