Hi everyone, I'm working on my own backtesting/ATS app (decided not to go with openquant afterall even though it seems very nice for what it does) and I don't want to download gigabytes (terrabytes?) of data if I can just buy it on DVDs. So far I have found: http://www.grainmarketresearch.com/int_futures.cfm http://www.tickdata.com/ ...both look interesting but I'm not sure about pricing. So I want high quality data on equities that I can just download all at one time or get on a DVD (or whatever) for a decent price. Any other recommended data providers? (I think it will take a very long time to download tick data from something like opentick for most US equities and then I'd still have to deal with all the weirdness in the opentick data) Thanks.
