TradeStation Help
When you start TradeStation, you'll be looking at the Desktop. The desktop includes the Menu Bar, Command Line, Tool Bar, Order Bar, Position Graph Bar, TradingApps, Status Bar, and the workspace area. In the Desktop, you'll be working with one or more tabbed workspaces, and it is in these workspaces that you add windows, much like you add sheets to a workbook when working in a spreadsheet application.
Think of the desktop as your overall organizational tool; it enables you to specify overall settings for your workspaces as well as the overall look and feel of TradeStation. You can have multiple Desktops open at once, each having a separate name and different settings.
For example, each desktop enables you to define how many workspaces to remember in your workspace list and globally toggle title bars on and off as well as other global features. The full list of desktop options is listed in Setting the Desktop Preferences.
