The Calendar is a thinkorswim interface that details scheduled earnings, conference calls, and economic events as well as anticipated dividend and split announcements. Watch an overview of this feature below.
The functionality of the Visualize tab will provide you with a visual representation of market data. Two modes of visualization are available: Heat Map and Index Watch (you can switch between these using the Visualize drop-down).
The Heat Map represents the price activity of symbols in a watch list based on three visual parameters: color, brightness, and area. Red rectangles represent symbols that have moved downward, while green represent those with upward price movement; the brighter the color, the greater the move. The area of each rectangle is proportionate to the company's market cap.
The Index Watch mode provides a visual representation of how the indices of user-defined watch lists are performing intraday.
The thinkBack tool is a thinkorswim feature designed for option back-testing. It stores nearly a decade of historical option trade data and allows you to back test strategies by entering hypothetical trades in this virtual trading environment.
Backtesting is the evaluation of a particular trading strategy using historical data. Results presented are hypothetical, they did not actually occur and there is no guarantee that the same strategy implemented today would produce similar results.
