Based out of Illinois, Think or Swim is a broker specializing in option trading. Their pricing structure caters to high volume traders and is intended to weed out smaller investors not willing to purchase large quantities in a single trade. They don’t charge some of the maintenance or inactivity fees you’ll see at other brokers. Their customer service is top notch and actually proactive if you are a big enough client. Overall ThinkorSwim is pushing the envelope on tools, software, and charting but may not be the best choice for newbie investors. If you are new to the game it doesn’t hurt to open an account because they don’t have an inactivity fee.
