How I Use Bollinger Bands
I am always using bollinger bands, especially when it comes to taking profits. It is a good way to manage my 'euphoria' or excitement when a stock is going up (or down) in my favor. Its easy to assume that it will continue in that direction in the midst of the trade. That's why I use bollinger bands to guard against those emotions, and avoid the common "profit-turn-loss" scenario. I've put together a video that you can view here.
