Finviz is a powerful online stock screener that I use often to see what is currently in play.  Screeners are programs that search thru thousands of stocks with specific parameters.  Finviz offers screening criteria such as stocks that are down 5%, having an average true range of at least 1pt,  below 200 moving average, etc.   Give it a try.  You might even see the same stocks alerted by Extreme-os
