instrument expiry

[pman777]

Need help with this ... I want to add an instrument to my indicator with the same expiry as the main instrument being processed. For instance, if I am running the indicator for NQ 03-19, I want to add "ED 03-19" with AddDataSeries. How do I go about identifying the expiry of the main instrument so I can keep the added instrument in sync? If you can point me to an example that would be greatly appreciated! thanks

Hello pman777,
Thanks for your post.

It is not currently possible to dynamically load a data series this way.

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.
