Here ya go. Basics of Bollinger bands: http://www.investopedia.com/articles/technical/102201.asp If you study charts, you know when stocks will pop and when they are ready to drop. Otherwise it is just a shot in the dark on rumors and ihub bs. Learn bollies, rsi, macd, sar, force index, candlesticks,moving averages and many more indicators, then you can bank. IMHO
