Bollinger Bands are generally placed two standard deviations above and below the market. Prices within the standard deviations are said to be 'normal' prices. Whenever the price moves below the lower band, this strategy generates a buy stop order for the next bar when the low price of the current bar has crossed back above the lower band. The stop value is the level of the lower Bollinger band.

You can change the number of bars and standard deviation used to calculate the Bollinger band.
