Bandwidth arguments aside. No one seem to mention latency. The amount of bandwidth that required really shouldn't exceed an ISDN or perhaps even a 56K modem if only one or two stocks are being watched. In case, people are wondering about the difference. Bandwidth is "the amount of data that can pass from the source to destination per unit time." Latency is "the time between sending the data from the source end to the far end." The most common way to measure latency is to use a round-trip-time calculation with the ping utility. It's really the latency between endpoints that's important. Some ISPs offer high-bandwidth DSL connections but if their internet connectivity is poor and the lower latency will effect the data. rtharp, I don't mean to sound skeptical but a T4 is a HUGE circuit. Unless your friend is using a T4 shared with a lot of people, it's just not cost-effective. Just to give people some perspective, a T4 is the equivalent of 178 T1s and is capable of 4032 simultaneous clear-channel voice conversations. It's a rarely used type of circuit.
