^SP500 bars object

[edmata1109]

I am a trying to add a bars object of ^SP500 to my script. Though my script compiles as written, the plot does not come up on my chart. Any suggestions on what I am missing?

Thank you

if (State == State.SetDefaults)
{
AddPlot(Brushes.Orange, "^SP500");
}
}
else if (State == State.Configure)
{
AddDataSeries("^SP500");
}
}

protected override void OnBarUpdate()
{

Values[0][0] = Closes[1][0];
}

Hello edmata1109,

Thank you for your post.

First, you're not adding the data series correctly. You need to specify the bars period type and the period value as well. For example, this would add a 1 minute data series of SP500:

AddDataSeries("^SP500", Data.BarsPeriodType.Minute, 1);

Here's a link to our help guide on AddDataSeries():

Also, you may want to add something like this to the top of OnBarUpdate to avoid running into issues if your primary data series isn't the same period as the added SP500 series:

if (CurrentBars[0] < 1 || CurrentBars[1] < 1)
return;

This just ensures that all the series have at least a certain number of bars before trying to process.

Please let us know if we may be of further assistance to you.
