Jeff, you can get intraday option info at Pc Quotes as well - it's just 15-minute delayed.

However, what I meant was that open interest is only computed once a day. You will never see the open interest change during the day using ANY quote service, as the exchanges don't compute or release the data during the day.

Bid, ask, last trade, volume of trade, and accumulated volume, yes. Open interest, no.

I may have misunderstood the question, but I thought that what was being asked about was open interest. (At least that's how I interpreted the request for "outstanding volume", not exactly sure what "outstanding volume" is. Does that mean "real good" volume? :) )
