Check out Interactive Brokers. Never had a problem with them in two years trading there. $.01/shr, cheap options, too. Fast, good fills, and can set trailing stops. Good trader workstation. Also get good service/fills at Muriel Siebert, but it's $14.95 up to either 1000 or 5000 shrs (can't remember which). Don't care much for the setup at Brown&Co., $10/100 shrs, but don't trade that account much. For day-trading, by far I.B. is my preferred account. Only use Siebert or Brown for swing or position trades.
