Our course on Double Bollinger Bands (DBB’s) is divided into several lessons. DBBs are a powerful variation on the standard single Bollinger Band, because they can tell us much more about momentum and therefore trend strength, both in flat and strongly trending markets.

Double Bollinger Bands are 2 sets of BBs, using default settings set at the usual 2 standard deviation distance above and below the 20 period simple moving average line in the middle, as well as a second set of BBs plotted just 1 standard deviation above and below that central moving average. Traders can, and do, tinker with the type and duration of the moving average and the number of standard deviations. The two sets of Bollinger bands create three zones and we will talk about each zone and what they mean relevant to the position of the price movements. We will explain the 4 rules associated with these zones, and how to follow them in order to trade profitably.
