I also have PC Quote it runs the Ned Davis computer I have. It is satellite fed and I
would assume that if the PC Quote internet feed is as fast as SP Comstock Satellite.
Then the satellite PC Quote would be faster than the internet product. It sets on the
other side of the room from me so its not side by side with the SPC,CQG,BMI feeds.
I never thought to compare, until now which I will today when I go in. You can ping the
server of any internet quote service and view the hops that a service makes to get to
you. Also in Win95 when you do this if one of the jumps has a * beside it has a
problem and had to be rerouted, which happens quite often I have found. So I give up
on internet feeds for now. If I cant find my own personal T-1 fast enough I doubt any
internet service could satisfactory. That goes for order entries also (just futures) I want
to talk to my broker with my tape running Thank You. Mark
