Preferrably for major stocks -- ETF's (DIA, SPY, etc.) or dow components. I only need the total volume from 7-8:30am.
Futures will not suffice.
I already use IB data, but this only goes back 1 year.
Sign up for the 30-day free Qcharts trial, get the Qcollector free demo (google it) and see if the the "Collect All Sessions" feature does what you need. If so, you'll probably want to buy Qcollector but it's only a few $.
