Volatility Analysis: Combining Bollinger Bands® and Average True Ranges By John Forman
I am not a huge fan of technical indicators, being primarily a chartist in my market analysis. That said, I do watch the volatility-based indicators to help get an idea of how the market is doing at present and what is likely to happen in the future. The two indicators I use in that regard are Bollinger Bands and Average True Range (ATR).
