Stock Scanner

A stock scanner is software that watches the stock market in real time.  Professional and active retail traders use a stock scanner to help them watch many stocks simultaneously instead of trying to find specific tradable situations by hand.  Trade-Ideas software is a type stock scanner that allows users to configure exactly the kind of trading set up that they want to watch without having to use programming or scripting.  Sometimes terms such as stock scanner and stock screener are used interchangeably, however this is a mistake, a stock scanner updates information in real time as it happens whereas a stock screener typically updates once and waits for the user to request another update.
