The Awesome Oscillator (AO) is an indicator used to measure market momentum. AO calculates the difference between a 34 Period and 5 Period Simple Moving Average. The Simple Moving Averages that are used are not calculated using closing price but rather each bar's midpoints. AO is generally used to affirm trends or to anticipate possible reversals.
