Awesome Oscillator (AO)

Overview

Bill Williams' Awesome Oscillator compares recent momentum to broader momentum using the difference between two simple moving averages of the midpoint price, making momentum shifts visually clear through its histogram. It pairs well with the MACD for layered momentum confirmation across stocks, crypto, and forex. Apply the AO on TradingView for real-time saucer and twin peaks setups, and integrate it into your trading strategies for systematic momentum trading.

How It Works

AO = 5-period SMA of (High + Low) / 2 minus the 34-period SMA of (High + Low) / 2. Positive histogram = short-term momentum above long-term. The colour of the bars (green = rising, red = falling) shows acceleration.

Key Signals

  • Zero-line crossover: AO crossing above zero = bullish; below zero = bearish.
  • Twin Peaks: two peaks on the same side of zero with a pullback in between signal continuation.
  • Saucer setup: three consecutive bars where the histogram dips then rises (bullish) or vice versa.
  • AO divergence from price indicates weakening momentum.

Common Mistakes

  • Using AO on very short timeframes — it's designed for 4H and daily charts.
  • Ignoring the colour change (acceleration vs deceleration) and only watching the zero line.
  • Not combining AO with price structure — the saucer signal needs context.

Gator Oscillator

The Gator Oscillator is a histogram companion to the <a href="/academy/indicators/alligator" class="text-primary hover:underline">Alligator</a> indicator, visualising the degree of convergence or divergence between the Alligator's three smoothed moving averages. It makes it easier to see when the Alligator is sleeping, awakening, eating, or sated — key phases in Bill Williams' trading system. Use both indicators together on <a href="/tools/platforms/tradingview" class="text-primary hover:underline">TradingView</a> and pair with the <a href="/academy/indicators/awesome-oscillator" class="text-primary hover:underline">Awesome Oscillator</a> for the complete Williams toolkit.

Williams %R

Williams %R is a momentum oscillator that measures where the current close sits relative to the highest high over a lookback period — essentially the inverse of the <a href="/academy/indicators/stochastic-oscillator" class="text-primary hover:underline">Stochastic Oscillator</a>, excelling at identifying reversal zones. It is most effective in range-bound <a href="/market/forex" class="text-primary hover:underline">forex</a> and <a href="/market/stocks" class="text-primary hover:underline">stock</a> markets where clear support and resistance levels exist. Combine %R with trend-following <a href="/strategies" class="text-primary hover:underline">strategies</a> to take only high-probability entries in the direction of the dominant trend.

ROC — Rate of Change

Rate of Change measures the percentage change in price over a specified period — the simplest momentum indicator that provides a clear picture of whether price acceleration is increasing or decreasing. ROC works across <a href="/market/stocks" class="text-primary hover:underline">stocks</a>, <a href="/market/crypto" class="text-primary hover:underline">crypto</a>, and <a href="/market/forex" class="text-primary hover:underline">forex</a>, making it a versatile addition to any <a href="/strategies" class="text-primary hover:underline">trading strategy</a>. Use ROC divergence as an early warning signal alongside tools from our <a href="/academy/indicators" class="text-primary hover:underline">indicator guide library</a> for multi-factor confirmation before entering a trade.

Money Flow Index (MFI)

Money Flow Index is a volume-weighted <a href="/academy/indicators/rsi" class="text-primary hover:underline">RSI</a> that incorporates both price and volume data, providing a more complete picture of buying and selling pressure than RSI alone. MFI divergence carries extra weight because it reflects real capital commitment, making it invaluable for <a href="/market/crypto" class="text-primary hover:underline">crypto</a> and <a href="/market/stocks" class="text-primary hover:underline">stock</a> traders. Pair MFI readings with your <a href="/strategies" class="text-primary hover:underline">trading strategies</a> and always confirm signals with price structure.
