"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

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
