The Gator Oscillator was developed by Bill Williams and is related to the Alligator Indicator
. It plots the level of divergence between the 3 alligator lines in 2 separate histograms. The histogram above the baseline shows the divergence between the blue and red line while the histogram below the baseline shows the divergence between the red and green line. The oscillator works best in a trending market. Due to its simplicity, the oscillator can be combined with the Alligator to form a standalone indicator or together they can be used in combination with other analysis techniques.
