historical bid/ask quotes

Quote from saminny:

Yes, but we need data for futures trading on comex, nymex, cbot as well.

If you can't find the information on the exchange websites then call the exchanges and ask them. All the exchanges are in the data business and want your money.
 
I find it incredible that only OpenTick used to have a somewhat usable service. CQG, for example, has a seemingly good service, but their time stamps have a minute granularity!
 
Quote from Davdse:

"tick-by-tick" data has a time granularity of one minute!
Call the CQG, they have the millisecond resolution for ticks as well as complete book changes with millisecond precision. It is just not available on-line.
