I like IB. It has fast execution and very good interests rate and great margin rate. However, if you trade penny stock, the commission is 0.5%, which is high. Its CS is the worst I have ever experienced.
Buy cheap, undiscovered stocks!
Disclosure: I usually own the stocks I post the most. The more I discuss, the more shares I own. Do you own DD before placing the trades.
