A system and method provides security information by allowing the user to choose from among tools that will be displayed to the user, some of which may be displayed in a manner that replaces a display of a different tool when the user selects it. Some tools such as a series of small charts displayed on the user's computer screen will display information regarding multiple securities, while multiple other tools display information about a single security selected by the user, for example, by the user clicking on the small chart corresponding to that security.
