What is Awesome Oscillator?

The Awesome Oscillator, from Bill Williams, compares recent momentum with a longer window by subtracting a 34-period simple moving average of the median price from a 5-period one.

Awesome Oscillator formula

Output	Calculation
Median price	(high + low) ÷ 2
AO	SMA(median, 5) − SMA(median, 34)

How to read Awesome Oscillator in your code

Signal	Meaning	Condition
Bullish zero cross	Short-term momentum moved above long-term	`value` moves from ≤ 0 to > 0
Bearish zero cross	Short-term momentum moved below long-term	`value` moves from ≥ 0 to < 0
Saucer	Momentum dips and resumes in the trend	Three values above 0, the middle one lowest

Limitations: The fixed 5 and 34 windows cannot be changed on this endpoint, and zero crosses lag in fast reversals. Nothing on this page is financial advice.
