I need a new broker as I am currently paying $19.95 per trade. Im not active enough to trade through interactivebrokers.com. Anybody have any experience with http://www.marsco.com? They advertise $3.95 trades. It seems to good to be true to me. Does anybody know what the catch is? There isnt even a review for them in the brokers section. What broker do those of you that only make a few trades per month use?
