Chart Crash adding second data series

[Skifree]

I was hoping to do a series comparison of correlated instruments (1min), and I've had no issues doing this before in backtests - but when I attempt to run a strategy on a chart loading the ES into a strategy with Primary NQ, the chart locks up and the whole app dies. I add the dataseries at the very end of State.Configure.

Is this a limitation I need to work around?

Hello Skifree,

This wouldn't be a limitation.

Are you using the latest release of NinjaTrader 8.1.4.1?

Attached is an exported test script to test your claim as well as the output I am seeing in the output window.
AddSecondaryInstrumentTest_NT8.zip
NinjaScript Output 2_13_2025 7_11 AM.txt

Is the attached test script experiencing the same behavior?

I will test it - but this is in a previous version of NT. Upgrading to the latest completely broke everything, so I had to roll back. Here use use AddDataSeries("NQ 03-25"); vs AddDataSeries("NQ MAR25"); - are the two synonymous?

Hello Skifree,

The symbology of the symbol can be changed if you are using a different symbology.

As the test script I've provided is not able to reproduce on my end using the latest release, we would not be able to report any issues unless you are able to reproduce with the latest release.

If there are things that were broken, these should be reported to our support team who can send a bug report to our development.
