Description:
Bill Williams. Awesome Oscillator (AC)
Formula Parameters:
- nLengthSlow : 34
- nLengthFast : 5
Notes:
This indicator plots the oscillator as a histogram where blue denotes periods suited for buying and red . for selling. If the current value of AO (Awesome Oscillator) is above previous, the period is considered
suited for buying and the period is marked blue. If the AO value is not above previous, the period is considered suited for selling and the indicator marks it as red.
