I'm looking for advice as to who is the best data provider for options. I require a composite quote (from all five Exchanges) best bid/ask, the bid/ask size and the bid/ask exchange. I need to bring these quotes into Excel via a DDE link. I would require a minimum of 500 quotes (series). I have used the following providers: 1) Quote.com - absolute joke for options 2) Esignal - not bad, but they have limitations in their DDE link. There is a maximum of 2,000 fields you can get (not enough for me - 500 quotes X 6 fields) 3) PC Quote - the best I have seen. I can get about 500 quotes via DDE with no limitation as to the number of fields. The main problem is that they occassionally miss a tick 4) DTNIQ (Interquote) - no DDE link - they have their own spreadsheet format - from what i remember the quotes were not very good 5) Reuters and Data Track - quotes are good but they DON't provide a composite quote. Without a composite quote, you would require five times as many quotes to do your analysis. Any advice would be appreciated. thanks.
