1For clients who intend to run the software on Linux, Solaris or other Unix variants, manual update of the software is required, and we have no official support for configuring these operating systems. 2We define power users as those who watch multiple charts at once, use our custom scripting language or perform complex technical analysis. Note: If you are using a non-Windows platform, some of the embedded content may not be available. Internet connections: You need a broadband Internet connection (DSL, cable, or faster) to run the thinkorswim platform. Access multiple locations: Your account information is stored securely on our servers. You can log in and access your account(s) from any computer that has installed our software. If you try to log in from multiple computers at the same time, you will not be able to access live quotes. Exchange regulations prohibit us from giving the same user access to live quotes from different computers simultaneously.
