NYX would be a third option... http://www.nyxdata.com/page/1070 Again, expen$ive. "TAQ Options U.S. covers regional options exchange quotes, options time & quotes, concomitant stock data, options time & sales, U.S. Options & Equity derivatives quotes at 1 minute and 15 minute intervals with...

You're looking for OPRA TAQ data (Trades AND Quotes), for 100 options/week. Are you looking for a different list of options for each day, or the same 100 all 5 days of the week? Do you have to collect once a week, or could you collect the data at the end of each day? Or in real-time? Are you...

Comparison Matrix: AGREED "data-splicer": This is a great idea. I would certainly use it. The closest solution I can think of is XLQ, as it pulls data from multiple sources, EOD and RT, free/paid, but I don't think it's really set up for the comparison/analysis step, that part you still...

Thanks, it was a single event. I'll post more if it happens again. It's still a mystery though (to me at least) as to why trading will sometimes occur below the NBB. I know very little about market microstructure, so I was hoping someone on the forum might have some insight...

B-firm = Interactive Brokers??

If you don't mind me asking, who are you using for your primary feed and what was your reasoning for choosing them?

fareastcoast - great point. Of the data providers you tested, which are "push" and which are "pull"? Also, still interested to hear if anyone has used QuoteCenter...

QuoteCenter at $135/mo. (MetaStock, powered by Thomson Reuters) looks like a pretty good option. I skimmed through their API doc that the sales rep sent me, looked like they much more available than eSignal, which is the only on of these options I've used. Anyone have any experience with...

OP- great review, thank you. Has anyone compared Thompson/Reuters/Equis, eSignal, Tradestation real-time equity feeds?
