Since 1999, thinkorswim has supported traders through innovative trading platforms that have been recognized as some of the industry's best for options trading. In our short history we have grown by leaps and bounds because we continue to focus on what we do best - delivering powerful, easy-to-use trading technology, supporting active traders over a wide range of products, and teaching the world a smarter way to seek risk management and spot potential opportunities. And now, as thinkorswim by TD Ameritrade, we are combining our innovative approach to trading with the independent research, portfolio management tools, strong client service capabilities and stability that TD Ameritrade has been known for. The goal of our combination has been to redefine and set a new standard for the brokerage industry, to make a better experience for today's traders, and - no surprises here - that's what thinkorswim has always been about.   Disclaimer Note:* thinkorswim, Inc. has entered into a Marketing Agreement with Cyber Trading University, Inc.(CTU) whereby thinkorswim pays CTU to recommend thinkorswim as its executing broker.
