There are countless options trading platforms. This is not an endorsement one way or the other of the Think Or Swim platform, but many of our students use this platform so I wanted to do a quick, basic tutorial. This is by no means meant to be a comprehensive lesson, but a nice starting point. For more complex questions, I highly encourage you to refer to the Think Or Swim Support/Chat. That can be accessed by clicking on the Support/Chat button in the upper right corner of your main TOS window.
