Configure State hit twice

[cmarkb]

Hi. We are using NT 8.0.18.1 64-bit and while developing our strategy we noticed that the Configure state is being hit twice and running our code twice.

We've tested this with the sample strategy SampleAtmStrategy.cs and updated OnStateChange code to be this:

protected override void OnStateChange()
{
    if (State == State.SetDefaults)
    {
        Description    = NinjaTrader.Custom.Resource.NinjaScriptStrategyDescriptionSampleATMStrategy;
        Name        = NinjaTrader.Custom.Resource.NinjaScriptStrategyNameSampleATMStrategy;
        // This strategy has been designed to take advantage of performance gains in Strategy Analyzer optimizations
        // See the Help Guide for additional information
        IsInstantiatedOnEachOptimizationIteration = false;
    }
    else if (State == State.Configure)
    {
        Print(DateTime.Now.ToString() + " " + guid + " " + State.ToString());
    }
    else if (State == State.Active)
    {
        Print(DateTime.Now.ToString() + " " + guid + " " + State.ToString());
    }
    else if (State == State.DataLoaded)
    {
        Print(DateTime.Now.ToString() + " " + guid + " " + State.ToString());
    }
} 

then added SampleAtmStrategy, pressed OK, and the output is this:

Is there a way so that Configure will only be run once? Thanks.

Hello cmarkb,

I just wanted to make a quick reply to let you know we are looking into this. Once I have more details I will reply back here.


I look forward to being of further assistance.

Hello cmarkb,

After speaking with QA it appears this is expected although not documented as an expectation. State.Configure seems to also be called multiple times like SetDefaults when used from a chart despite the help guide noting it should only be run once. The note we have about this happening for SetDefaults does not include Configure specifically which creates some confusion. There are cases where it does get executed more than once like SetDefaults, however the other executions are from the menu instances, not the chart instance. For one time actions, I would suggest moving what you can to State.DataLoaded to avoid this.

Was there a more specific example you can provide which is affected by this being called more than once? Are you seeing a specific NinjaScript property that requires State.Configure failing due to this, or was this for your own logic and uses?
