Bollinger bands is very useful indicator. You can use it very easily for you chart. Many trader use bollinger bands and trader with it. Mainly bollinger bands tradeing system is long when price touch lower band.
Short when price touch upper band. Exit trade middle band. I think every trader trader like this. But they use some other indicator for perfect entry. I use bollinger bands with defalt setting and I also use stochastic, 200 EMA and 50 EMA.
