Bollinger bands are about the best indicator you will ever use to help identify high probability trades. Bollinger bands measure a standard deviation from the mean or middle. Usually the “mean” or middle is a 21 day moving averade of closing price.

So you would lay down a 21 day moving average and then a 2.0 standard deviation set of Bollinger bands and when price closed outside of either band it is said to have closed outside a 2 standard deviation band. 2 standard deviations from the mean.

To profit in currency or forex trading you need to master the techniques and choose the techniques that are working for you when practising them on a practice account. The rule is, don’t trade real money before proving your skills on a practice account. I would recommend trading on a practice account for at least a month before opening a real money account. The site i got this information has a video to show you how to trade bollinger bands
