TD Ameritrade offers 60 day of free trading when you open a new account. Even better they give a cash bonus that escalates with your deposit, ranging all the way up to $600. This is a $100 increase from our last post. This site gives you access to free tools, research, and support to make decisions for making investments (both short-term and for retirement). The account is free and after the trial period is over trades are $9.99.
