Robert,
I have run them both on the same computer for months on end. I use DTN
satellite and have used several different internet connections from
cable modem to ISDN and 56K with different suppliers. I used TS6 for
some time also. I find the internet price will arrive a fraction of a
second before the satellite price is many cases. However you can only
get a few symbols internet before the line is overwhelmed. I collect
over 20,000 symbols from DTN and have collected over 30,000 with no
problem. I know you couldn't collect nearly that many by internet from
one source even with T1.
Math tell us it is 50,000 miles round turn to a satellite so with a
radio transmission running at 286,000 miles per second it takes less
than a fifth of a second to travel up and down. Equipment delays
probably add some more delay but my trading isn't good enough to worry
about even a one second delay. One other factor is the order in which
the trades are sent. Some vendors give priority to one set of symbols
over others.

Subject: Sattelite datafeed faster than landlines ?
Hi List,
I seem to have a discussion with a friend of mine who claims that a
sattelite connection (for instance with S&P Comstock) has a faster
throughput than a landline (internet ADSL or T1).
I believe that due to the propagation delay (signal travels up and down
to
the sattelite) the landline should "always" be faster !
Any ideas?
Anybody with experience or maybe who has both ?
Thanks
Robert
