I use satellite but ISDN, DSL or cable would be just fine. I do not like trading with just a 56k modem. Last and most important is direct trading to Island. I trade using Real Tick software and get almost instantaneous executions. You must be with a trading firm that offers fast executions.
Seconds do count when day trading.
It speaks for itself. I would rate them BEST OF THE WEB . I ve been trading for three years but still rely on them to identify low and high points for inter-day entry and exits. Early alerts allow time to catch the real bottom. In addition, short side trades have been much more profitable for me since joining Millennium-Traders.
