Quote from alanm:
If QT is getting the data from IB, it is not true T&S. It can't be if IB does not provide it. It's the snapshot data, perhaps with some enhancement to make the volume total correctly.
IBSoft: Can you confirm that you are saying you will provide true T&S retrieval? This seems contrary to the earlier comment about not changing the quote strategy (which I like).
If you mean you will allow snapshot retrievals of a time range of actual rows from the tape, that would be nice. I'd like to be able to do it from a market data row, too - not just a chart. A quota system could keep this from being abused via the API, yet still provide the ability to get the data for some instruments from TWS when that data is not easily available elsewhere (like NYMEX products, last time I searched).
