Bollinger Bands

Bollinger Bands are intervals drawn on a price chart that define high and low on a relative basis. Bollinger started developing Bollinger Bands in the early 1980s. They are an adaptation of Keltner Bands and similar to Donchian channels. He was trading options at the time and much of his analytics involved volatility. At the time fixed width trading bands were in use. Mr. Bollinger's contribution was to use volatility standard deviation to make trading bands adaptive.

When they were introduced to the public on Financial News Network they didn't have a name. His interviewer pointed to the chart and said "What are those?" and Bollinger said "Let's call them Bollinger Bands." That was how they got their name.
