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).
Die Idee in einfachen Worten
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.
So wird gerechnet
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)Anwendung
- 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.
Schlüsse ziehen
- The wider the gap between the lines, the stronger the trend.
Beispiel
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.
Kurse in Beispielen dienen der Veranschaulichung.
Worauf man achten sollte
- The lines are slow; part of every trend is gone by the time they fan out.
