Object reference not set to an instance of an object.

[billythekid72]

Hello,

In my strategy, I tried to add a second data series, and the strategy returned an error: "Error on calling 'OnStateChange' method: Object reference not set to an instance of an object."
Please advise what did I do wrong? Is it because my second data series time period is larger than the primary? My chart has only the primary data series displayed.

else if (State == State.Configure)
{

AddDataSeries(Data.BarsPeriodType.Tick, 1);

// Add daily VIX data series
AddDataSeries("^VIX", BarsPeriodType.Minute, 1);
}

Best,

Billy

Hello Billy,

Are you 100% certain that code is causing the issue?

Have you created a new test script and added only that code and ensured the reduced test script with only that code is able to reproduce?

I'm testing and I am not able to reproduce.

Can you provide an export of the reduced test script that has only the code you posted in post # 1?

To export a NinjaTrader 8 NinjaScript so this can be shared and imported by the recipient do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) and reference(s) you want to include
3. Click the 'Export' button
4. Enter a unique name for the file in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>

Below is a link to the help guide on Exporting NinjaScripts.

Once exported, please attach the file as an attachment to your reply.

Hello Chelsea,

Thank you for your response, turns out it was something else. I was accessing Time[0] before the DataLoaded state, I have fixed the problem.

Best,
