It depends if you want to watch data on the combined electronic/pit session or only the electronic session. The + symbol is the combined session. QNG for example will give you only the electronic session trades.

Thank you.
I'd like to view "smooth" charts, without spikes and unordered deals. Should I choose Q-prefix in this case?
Thx

Hi Jay, I was wondering if you could say any more about how the combined session data is produced?

Is this done at the exchange source or internally by your feed infrastructure?

Is the time-ordering correctly preserved when the streams are merged?

thanks
