Types

Awesome Oscillator is core component of Bill Williams trading system, typically used with Alligator indicator and Fractals. AO zero line crossovers are important trend signals but may generate false signals in ranging markets. Twin peaks and saucer signals are AO-specific pattern signals with higher reliability. AO divergence is powerful reversal signal, especially when occurring near key support/resistance. Many traders combine AO with other momentum indicators to improve signal accuracy.
