    GUI parameters

    I have a multi-instrument strategy with an array of Add() contracts. In the GUI I want to have a parameter that inputs the current expiry month (06-20) for each array member.

    [Description("ES Current Expiry Contract")]
    [Category("Parameters")]
    [Display(Name="ES Current Expiry Contract", Order=5, GroupName="My Parameters")]
    public double ESExpiryMonth
    {
    get { return eSExpiryMonth; }
    set { eSExpiryMonth = value; }
    }


    which would insert the value as so:


    AddDataSeries("ES &" "& eSExpiryMonth", new BarsPeriod { BarsPeriodType = BarsPeriodType.Minute, Value = 405 }, "CME US Index Futures RTH");


    Am I on the right track here?
    Regards

    Hello elliot5,

    As a heads up, using dynamic variables with AddDataSeries() is officially not supported by NinjaTrader to do.

    From the help guide:
    "Arguments supplied to AddDataSeries() should be hardcoded and NOT dependent on run-time variables which cannot be reliably obtained during State.Configure (e.g., Instrument, Bars, or user input). Attempting to add a data series dynamically is NOT guaranteed and therefore should be avoided. Trying to load bars dynamically may result in an error similar to: Unable to load bars series. Your NinjaScript may be trying to use an additional data series dynamically in an unsupported manner."
    https://ninjatrader.com/support/help...dataseries.htm

    I think you are wanting to concatenate a string as the instrument symbol, is this correct?
    Something like
    "ES " + ESExpiryMonth

      Yes that is correct.
