Q1) If I will only follow 1 stock intraday, with a dynamic real-time price, one intraday chart, and real time Time/Sale for that stock (and maybe L2 for that one stock), would 56k modem be good enough? Q2) Dial-up or DSL, which is the best ISP for trading? What's the difference between Tier1 ISP and the rest? If I go for DSL, which do you recommend: AOL, MSN, AT&T, Earthlink , or whatever else ...? If I continue to use dial-up only which is the best? (I have AOL and MSN now.) Which of the free-ISP's are the best?
