Hi, Fred Yes, I'm still here, but not for long. Getting ready to shut down and enter my "other" life for the night. I understand your point, which is well taken. My thinking was that it would be a major job to store all the data for the entire preceding day for all the stocks in the market, not just one stock for a particular hour of the data, or whatever. For CyBer to provide the service you describe, though, seems to me they would have to store everything from the day before. That's quite a lot. You say CyBerX already has this. Well, I did not know that, obviously, so nothing I've said matters at all. I should have kept my mouth shut! :-} Have a great weekend! Bill

Fred: I agree that the ability to 'replay' a days worth of data would be very useful for many people. I do have a bit of experience with the amount of storage space it takes to store a days worth of data. In late 1997, I stored all level II data for 20 active Nasdaq stocks. The storage space required amounted to 300 MB per day for these 20 stocks. I would guess that saving all Nasdaq data would likely take 2-3 GB per day. After saving this data for about two months, I decided to stick with Bill's suggestion and just focus on real time data each day. It just wasn't worth the problems to save the data. -Eric
