    When can I access an added data series in State == State.DataLoaded ?

    Hello,

    I added a ^VIX data series in my code, please see below:

    else if (State == State.Configure)
    {
    AddDataSeries(Data.BarsPeriodType.Tick, 1);

    AddDataSeries("^VIX", BarsPeriodType.Day, 1);
    ​}


    When I try to access the ^VIX data series in State.DataLoaded, please see below

    else if (State == State.DataLoaded)
    {
    Print("=========================================== ===========");
    Print("^VIX 10 days moving average" + EMA(BarsArray[2], 10)[0]);
    Print("=========================================== ===========");​
    }


    I got the following error message:

    Strategy 'AGG6BarDailyMonthlyVIX': Error on calling the 'OnStateChange' method: Object reference not set to an instance of an object.

    However, if I access the same data series in OnBarUpdate(), it worked fine. Please advise how can t I access it when data has been loaded in State.DataLoaded? Thanks

    else if (BarsInProgress == 2)
    {
    Print("=========================================== ===========");
    Print("^VIX 10 days EMA " + EMA(BarsArray[2], 10)[0]);
    Print("=========================================== ===========");
    }

    Hello billythekid72,

    Bar data is not available until the bar data is processed in OnBarUpdate().

    You can initialize an indicator in State.DataLoaded, change colors, properties, etc, but it has not yet started processing data.

    To use an index [0] and get a bar value, this must be done in OnBarUpdate() where data is processed.
