Secondary symbol in NT8

[MAX]

Hi,

I have a NT7 indicator which plot value for a secondary symbol (to be used for spread),
I can't plot the same in NT8.

Thats my code:

#region Variables      
private string symbol2 = @"^SP500"; // Default setting for Symbol2
#endregion

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;
if (CurrentBars[0] < BarsRequired || CurrentBars[1] < BarsRequired)
return;
Value[0] = Closes[1][0];
}

I'm repeating the same in NT8 but the indicator doesn't plot anything (please see attached code).
Am I missing something in NT8?

Thanks.

Hello MAX,

Thank you for your note.

Under State.Configure in NinjaTrader you may be using,
Add(“^SP500”, PeriodType. Daily, 1);

However in NinjaTrader 8, you should use,
AddDataSeries("^SP500", Data.BarsPeriodType.Day, 1);

Which would allow your logic under OnBarUpdate() you’ve shared to successfully plot the value of SP500, assuming you also have something like AddPlot(Brushes.Blue, "myPlot"); under State.Configure as well.

Please see Code Breaking Changes from NT7 to NT8.
