For stock-trading, I look for bottoms. Double, triple, etc. They're all good. But right now I just screen for stocks within a certain percentage of 52 week lows and then it's hit and miss if they are bottoming. Anyone know of a (hopefully) free website that scans for double bottoms for you? It seems something that a computer would be very good at. www.stockcharts.com is excellent but doesn't have a screen for bottoms. Any help appreciated.
