IB. They're cheap and fast. Occasional connectivity problems, but they're up and running most of the time. Corallus
I trade with IB and RealTick using Direcway Satelitte for hook-up and best connection 33.6 dial-up as back-up.
was with scottrade...probably sufficient if you're a long term trend follower or even a multi day swing trader...but those $7 and $12 commissions really add up switched to IB, have had no complaints. When and if I become a hard core day trader I would move to trading at a firm. using a cable modem and back up 56k dial up. and the $1 commissions rock.
freetrade.com first 25 trades each month are free. Then $3 for next 150, then $2, then $1. Works great.
Should have been: freetrade.com first 25 trades each month are free. Then $3 for next 75, then $2 for next 100, then $1 for any more. Works great.
