Alligator is a technical analysis tool consisting of three smoothed moving averages with periods of 13, 8 and 5, which are all Fibonacci numbers overlaid on a price chart. The lines represent the jaw, the teeth and the lips of the alligator. This indicator is used to determine the trend and predict its future direction. The Alligator indicator works best when combined with an oscillator-type indicator such as the Fractals indicator. The Fractals are recurring patterns that can predict reversals among larger, more chaotic price movements.
