The Awesome Oscillator (AO) is a powerful momentum-based technical indicator designed to help traders identify market trends, gauge momentum strength, and detect potential reversals. Developed by renowned trader Bill Williams in the 1990s, the AO stands out for its unique calculation method and visual clarity, making it a favorite among both novice and experienced traders.
Unlike traditional oscillators that rely solely on closing prices, the Awesome Oscillator uses the median price—the average of each candle’s high and low—to smooth out volatility and deliver a more balanced view of market sentiment. This approach reduces the impact of sudden price spikes or manipulation near session closes, offering a cleaner representation of underlying momentum.
How the Awesome Oscillator Works
The AO is displayed as a histogram that fluctuates above and below a zero line. Each bar represents the difference between two simple moving averages:
- A 5-period Simple Moving Average (SMA) of median prices (short-term momentum)
- A 34-period SMA of median prices (long-term momentum)

When the 5-period SMA is greater than the 34-period SMA, the histogram appears above zero, signaling bullish momentum. Conversely, when the short-term average falls below the long-term average, bars appear below zero, indicating bearish momentum.
Color changes in the histogram—from green to red or vice versa—signal shifts in momentum strength and are key to identifying trade setups.

Understanding the Zero Line and Momentum Shifts
The zero line serves as the central pivot point of the Awesome Oscillator. It separates bullish from bearish territory and plays a crucial role in generating trading signals.
- Bullish Signal: When the AO crosses above the zero line, it indicates that short-term momentum has overtaken long-term momentum—often a sign of an emerging uptrend.
- Bearish Signal: A cross below zero suggests weakening short-term momentum and potential downward pressure.
However, not all crossovers are equally reliable. Traders should watch for "side zero"—when histogram bars hover near the zero line—indicating low momentum and possible consolidation. In such phases, it's best to wait for stronger bars to form before acting.
A rarer condition called "bars zero" occurs when the 5-period and 34-period SMAs are exactly equal. This neutral state may precede a significant shift in trend direction, especially if preceded by strong momentum in one direction.
Key Trading Signals from the Awesome Oscillator
Traders use several well-defined patterns to interpret the AO and generate high-probability signals.
1. Zero Line Crossover
This is the most straightforward signal:
- Buy Signal: AO crosses above zero after being below.
- Sell Signal: AO crosses below zero after being above.
While effective in trending markets, this signal can produce false entries during sideways movement. Always confirm with price action or additional indicators.
2. Twin Peaks Pattern
The Twin Peaks strategy identifies potential reversals by comparing two swing points on the histogram.
- Bullish Twin Peaks: Two troughs below zero, where the second is higher than the first. This shows fading bearish momentum. Enter long on a subsequent zero-line crossover.
- Bearish Twin Peaks: Two peaks above zero, with the second lower than the first. Indicates weakening bulls. Consider shorting after a bearish crossover.
3. Saucer Pattern
This pattern captures early signs of momentum shift within an ongoing trend.
- Bullish Saucer: Three consecutive bars above zero—middle bar lowest, third bar rising. Suggests pullback ending; ideal for adding to long positions.
- Bearish Saucer: Three bars below zero—middle bar highest, third bar falling. Warns of renewed selling pressure; a cue to go short.
How to Calculate the Awesome Oscillator
Though most platforms compute the AO automatically, understanding its formula enhances comprehension:
Awesome Oscillator = 5-period SMA of Median Price – 34-period SMA of Median Price
Where:
Median Price = (High + Low) / 2
No complex multipliers or smoothing factors are involved—just pure comparison between short- and long-term averages of intrabar price extremes.
Practical Applications in Trading Strategies
The AO isn’t just a standalone tool—it shines when combined with other indicators to filter noise and confirm signals.
AO + MACD: Confirming Momentum Trends
Both measure momentum but differ in methodology:
- AO uses median prices and SMAs.
- MACD uses closing prices and EMAs.
When both indicators cross in the same direction (e.g., AO above zero and MACD line crossing signal line upward), it confirms strong bullish momentum. This dual confirmation reduces false signals significantly.
AO + RSI: Combining Momentum and Overbought/Oversold Levels
RSI identifies extreme conditions (above 70 = overbought, below 30 = oversold), while AO confirms actual momentum direction.
- Strong Buy Setup: AO crosses above zero + RSI rises from below 30.
- Strong Sell Setup: AO crosses below zero + RSI drops from above 70.

AO + Bollinger Bands®: Timing Reversals at Volatility Extremes
Use Bollinger Bands to spot overextended prices:
- If price touches the lower band and AO forms a bullish saucer or crosses up through zero → potential long entry.
- If price hits upper band and AO shows bearish saucer or downward crossover → consider shorting.
AO + EMA: Aligning Trend and Momentum
Ensure price is above a key EMA (e.g., 50 or 200) before taking bullish AO signals. Similarly, only act on bearish AO crosses if price is below the EMA. This keeps trades aligned with the dominant trend.
Advantages of Using the Awesome Oscillator
- ✅ Clear Visual Feedback: Green/red bars make momentum shifts instantly visible.
- ✅ Effective in Trending Markets: Excels at confirming trend direction and strength.
- ✅ Simple Yet Powerful: Easy to learn but capable of generating advanced signals like divergence and twin peaks.
- ✅ Versatile Across Timeframes: Works well on daily charts for swing trading or M15/M5 for scalping.
Limitations to Be Aware Of
- ❌ Lagging Nature: Based on moving averages, so signals come after price moves.
- ❌ False Signals in Choppy Markets: Whipsaws common in ranging conditions.
- ❌ No Overbought/Oversold Zones: Unlike RSI or Stochastic, AO doesn't define extreme levels.
- ❌ Not a Standalone System: Best used with confirmation from price action or other indicators.
Frequently Asked Questions (FAQ)
Q: What are the default settings for the Awesome Oscillator?
A: The standard configuration uses a 5-period SMA and a 34-period SMA of median prices. These settings are widely accepted as optimal for capturing meaningful momentum shifts.
Q: Is the Awesome Oscillator leading or lagging?
A: It’s a lagging indicator, derived from historical moving averages. While it helps confirm trends, it cannot predict price moves with certainty.
Q: Can I use the AO for scalping?
A: Yes. On lower timeframes like M5 or M15, patterns like zero-line crossovers and saucers can identify quick momentum plays—especially when confirmed by volume or support/resistance breaks.
Q: How does the AO differ from MACD?
A: Both compare moving averages, but AO uses median prices and SMAs, while MACD uses closing prices and EMAs. MACD also includes a signal line for additional filtering, making it slightly more nuanced for timing.
Q: Does the AO work well with cryptocurrencies?
A: Absolutely. Due to strong trends in crypto markets, the AO effectively captures momentum swings in assets like Bitcoin and Ethereum—particularly useful during breakout phases.
Q: What’s the best way to avoid false signals?
A: Combine AO with trend-following tools (like EMAs) or volatility filters (like ATR). Avoid trading crossovers in sideways markets unless supported by clear chart patterns or volume spikes.

Final Thoughts
The Awesome Oscillator remains one of the most intuitive yet insightful tools for analyzing market momentum. Whether you're identifying early trend reversals via divergence, confirming entries with twin peaks, or refining timing using saucer patterns, the AO offers actionable insights across various trading styles—from day trading to position holding.
Its strength lies not in isolation but in synergy. When paired with complementary indicators like RSI, MACD, or Bollinger Bands®, the AO becomes part of a robust decision-making framework that improves signal accuracy and risk management.
Ultimately, success with the Awesome Oscillator depends less on complex tweaks and more on disciplined execution, proper context analysis, and consistent risk control. With practice, it can become a cornerstone of any technical trader’s toolkit.
