True Relationship Revealed!
The Link Between Bollinger Bands And The Commodity
Channel Index
by Neil Jon Harrington
Bollinger Bands and the commodity channel index (CCI) have been
employed independently, in conjunction with other indicators, and with
each other. Could standard deviation bands around price action be a generalization
of an oscillator plotted below the prices?
IN my work in technical market analysis
(TMA), I never really considered the commodity channel index (CCI) until
December 2003, when I attended a conference of Woodie's CCI Club, highlighted
by a talk by CCI creator Donald R. Lambert. Seeing so many people willing
to come to a conference just to discuss one indicator got me curious. That
curiosity led to my own study of the CCI in December 2003 and early January
2004. During that time, I happened upon an interesting relationship between
the CCI and John Bollinger's work with standard deviation bands, which
he coined "Bollinger Bands."
INITIAL RESEARCH
When I got home from the conference, I started experimenting with the
CCI in the emini Standard & Poor's 500 market. I noticed it looked
a lot like Bollinger's %B indicator, which I sometimes use. I changed a
default setting of the %B and it became so close to the CCI that they had
to be mathematically equivalent, or very close to it. That intrigued me
even more.
But before going any further into my research, let's review the technical
foundation of the commodity channel index and Bollinger's Bollinger Bands.
