Thinkorswim offers hour trading five days a week for eligible securities, which makes the trading experience a bit more exciting. The advanced Mobile Trader app, with the power of the think-or-swim platform, streams as much data as your screen can display and includes the ability to plan and trade complex options. These advanced tools include a performance risk tool which lets you figure out what will happen to your portfolio based on movement in an individual stock or options trade, or for your entire portfolio.
