ToolTip
A ToolTip is a small, pop-up box that appears when you hold your pointer over a certain screen element, such as a cell containing a symbol. The pop-up box displays quick, reference information. For example, the ToolTip for a symbol might display the symbol description and the exchange on which the symbol is traded.
TradeStation allows you to modify the display of certain types of ToolTips, such as RadarScreen ToolTips.
