Bill Williams indicators
Alligator
Three smoothed averages (jaw, teeth and lips) shifted into the future: when they are tangled the "alligator sleeps" (no trend); when they fan out, it "eats" (trend).
La idea en pocas palabras
Markets trend only part of the time. The three lines, each slower and shifted further forward, help you see whether the market is resting or moving, and in which direction.
Cómo se calcula
Smoothed moving averages of the median price (high + low) ÷ 2: Jaw 13 periods shifted 8 candles, Teeth 8 shifted 5, Lips 5 shifted 3.
Jaw = SMMA(median, 13) shifted 8 forward (blue)
Teeth = SMMA(median, 8) shifted 5 forward (red)
Lips = SMMA(median, 5) shifted 3 forward (green)Cómo usarlo
- Lines intertwined: no trend, wait.
- Lips above Teeth above Jaw, all rising and spreading: uptrend; the reverse order: downtrend.
- Exit or tighten stops when the lines start to converge again.
Sacar conclusiones
- The wider the gap between the lines, the stronger the trend.
Ejemplo
After a week of tangled lines on GBPUSD H4, the green line crosses above red and blue and the three fan out upward: the alligator wakes up hungry.
Los precios de los ejemplos son ilustrativos.
Ten cuidado con
- The lines are slow; part of every trend is gone by the time they fan out.
