This screen finds stocks whose Alligator Lips have just crossed below the Teeth. The Alligator, developed by Bill Williams, uses three smoothed moving averages shifted forward: the Lips (5 periods, shifted 3), the Teeth (8, shifted 5) and the Jaw (13, shifted 8). When the lines are intertwined the Alligator sleeps; when they spread apart in order it is eating, and a trend is under way. This crossover is an early signal that a downward trend may be starting.
