The Chaikin Oscillator is created by subtracting a 10-period
EMA of Accumulation/Distribution from a 3-period EMA of
Accumulation/Distribution. This allows us to analyze accumulation
and distribution in the convenient form of an oscillator. It is
recommended to look for divergences between the oscillator
value and price. A second way to use the oscillator is to look
for a change of direction as a buy or sell signal.
