Has anyone used this broker? I ran across them while looking for a new broker to replace Scottrade. They charge a commission of $2.50 per trade. They have what appears to be very competitive margin rates and offer much better interest on account balances than Scottrade does by a long shot. They are a subsidiary of Success Trade Securities which I have to admit I have never heard of until I ran across them in my search. They have free checking, offer a debit card and ACH transfer as well. Any information anyone could provide would be much appreciated. I am a fairly active trader AND I need to get my costs down. Comments, suggestions?? Thanks.
