Q: Tips

- AO is a key component of the Bill Williams trading system - The "saucer" signal is considered more reliable than simple zero-line crossovers - Combine with the Alligator indicator for Williams' complete trading system - AO histogram colors help visualize momentum acceleration/deceleration - Works on all timeframes, but daily charts provide the most reliable signals

Question 1

What is Awesome Oscillator?

Accepted Answer

The Awesome Oscillator (AO) is a momentum indicator developed by Bill Williams that measures market momentum by comparing recent price action to a longer-term benchmark. It calculates the difference between a 5-period and 34-period Simple Moving Average of the bar's midpoints (H+L)/2.

Question 2

How it works

Accepted Answer

AO uses midpoint prices rather than close prices: ``` AO = SMA((High + Low) / 2, 5) - SMA((High + Low) / 2, 34) ``` AO oscillates around zero. Positive values mean short-term momentum exceeds long-term; negative means the opposite.

Question 3

Key features

Accepted Answer

- **Above 0** — Bullish momentum (short-term MA above long-term) - **Below 0** — Bearish momentum (short-term MA below long-term) - **Green bars** — AO is rising (increasing momentum) - **Red bars** — AO is falling (decreasing momentum) - **No user parameters** — Uses fixed 5 and 34 period SMAs

Question 4

Buy signals

Accepted Answer

- AO crosses above 0 (zero-line crossover) - "Saucer" setup: two consecutive green bars below zero - Twin peaks: bullish divergence with two troughs below zero

Question 5

Sell signals

Accepted Answer

- AO crosses below 0 (zero-line crossover) - "Saucer" setup: two consecutive red bars above zero - Twin peaks: bearish divergence with two peaks above zero

Question 7

Example conditions

Accepted Answer

| Condition | Meaning | |-----------|---------| | `AO > 0` | Bullish momentum | | `AO < 0` | Bearish momentum | | `AO cross_over 0` | Momentum shifted bullish | | `AO cross_under 0` | Momentum shifted bearish |
