Trade King has worked very well for me as the brokerage for my account. They have low fees and a ton of information on their website. I have learned a lot over the last couple of months just from the info available there.
Trade King has a $50 referral fee paid to account holders (i.e. me) who refer by email someone who opens a new account. I have added a link in the right column of this blog if you would like to have information from Trade King emailed to you. If you open and account I would be paid the referral fee. I think it is a great idea, but do what you want, no pressure.
