With over 19,000 stock charts to look at every day, professional analysts use sophisticated technical scanning programs to quickly find stocks with the best potential for profitable moves. StockCharts.com makes many of those same scans (sometimes called "screens") available to you on a daily basis. Our predefined scans are now grouped by type with a "Summary" page that shows you the number of results for each scan. Each scan's results are linked to several different charting tools for easy study. (Hint: Position two browser windows so you can see the chart and the scan results at the same time.)
