Resurrecting this thread.... So, I decided to double up on my key instruments and bought VIX and SPX options from these guys. The whole EOD package (with "vols" calculated) was about the same price as the whole set from 2002 from one of the other dealers, which made me cringe but ok, whatever.... Guess what? The data is a tad better but not a knock-em out of the park better. In the end, I am actually trying to combing SPX from two sources plus SPYs and VIX from two sources. Blah.Quote from PocketChange:
livevol is really expensive $6000 just for 1 month of 1 minute quotes for all option symbols.

inevitably if you haven't been collecting the data yourself.. your subject to everyone elses distortions.. how far did you get back historically? and just out of pure nosey curiosity what are you planning to do with that pair.. you obviously are volatility trading..
