Event-driven analysis is often used to predict what might happen in the future based on what has happened in the past. Many analysts will do research to determine when a certain event or set of events occurred and then study how the market reacted in the following hours, days, weeks, months, or further. The SHOW WHEN query is designed to help the user answer the question what happened in the past when this event occurred? Using the Query Wizard, it is possible to quickly and easily build and refine an event driven study.
