Williams Alligator

Trend

Williams Alligator on a BTC/USDT 4h chart on GG Charts
What it shows

Three smoothed lines, the jaw, teeth and lips, that open and close like a mouth. When they are apart the market trends, when they are tangled it is resting.

How it is built

Each line is a smoothed average of the bar's midpoint, with a different length and shifted forward in time: jaw 13 and 8, teeth 8 and 5, lips 5 and 3.

Default: Jaw 13 (offset 8), teeth 8 (offset 5), lips 5 (offset 3).

How traders read it
  • Lines in order and apart: a trend.
  • Lines tangled together: the market is sleeping.
  • Price far from the lines is read as stretched.
History
