Secondary data series count is always zero

[walley]

I'm not sure if I'm doing this correctly, but it seems that my secondary data series count is always zero.
The _secondaryDataSeries is always zero.

            // How I'm adding it
            else if (State == State.Configure)
            {
                // Secondary data series
                AddDataSeries(Instrument.FullName, BarsPeriodType.Range, 30);
            }
            else if (State == State.DataLoaded)
            {
                _secondaryDataSeries = new Series<double>(BarsArray[1]);
            }

           // Trying to get regression channel data
           Math.Round(RegressionChannel(_secondaryDataSeries, 35, 2).Upper[1], 2);​

Among other things, you can't use Instrument.FullName in State.Configure as the Instrument property may be null causing your indicator to exception out - try sending null instead or use a different overload so you don't have to send which instrument and it will assume the same one on the chart.

Hello walley,

Where are you printing BarsArray.Count()? Is this being printed in OnBarUpdate()?

QuantKey_Bruce is correct, using the Instrument property in State.Configure is not supported, and you would need to use null.

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."

"Tips:
4. For the instrument name parameter null could be passed in, resulting in the primary data series instrument being used."

Testing this on my end, I am seeing BarsArray.Count() has a value of 2.

Oh, I see. Thanks for the help all.
