The icon for these alerts describes the chart of the corresponding stocks.  Start with the stock's closing price from the previous day.  Follow the stock down to today's low.  Report an alert when the stock returns 25% or 75% of the way from the low back to the close.  A stock can report these alerts more than one time per day.

Note:  These alerts examine and report on every print.  These alerts do not filter out or otherwise correct bad prints.  These alerts are typically used as a warning of something coming, so these alerts report as quickly as possible, rather than waiting for confirmation.

Our proprietary filtering removes the most insignificant moves.  More filtering options related to these alerts are listed below.
