Williams Alligator

Sleeping: When the three lines are intertwined, the market is range-bound (the Alligator is sleeping). Avoid trading.

Eating: When the Green line (Lips) crosses out of the Red (Teeth) and Blue (Jaw) lines, the trend is beginning.

Open Mouth: If Green > Red > Blue, it is an Uptrend. If Blue > Red > Green, it is a Downtrend.
