Alligator + Fractals + Signals

Bill Williams' classic Alligator, extended with what the standard version lacks: automatic market-phase detection, filtered fractals, entry/exit signals and alerts.

What it shows

Three smoothed moving averages (SMMA), shifted forward, form the Alligator's "mouth": Jaw (13/8, blue), Teeth (8/5, red), Lips (5/3, green). The indicator reads their relative position and translates it into a clear market state:

• Sleeping (gray background) — lines are intertwined, the market is ranging. Best to stay out.
• Waking up — lines start to separate.
• Eating ↑ / Eating ↓ (green / red background) — lines are stacked in order, a trend is in progress.

A table in the chart corner displays the current state, line spread as a % of price, and where price sits relative to the Lips.

Fractals

Standard 5-bar fractals with Williams' filter: only "valid" ones are shown — highs above the Teeth and lows below the Teeth. Fractals inside the mouth are hidden to keep the chart clean.

Signals

• BUY / SELL — the lines have just aligned into a trend order, the Alligator is awake, and price closed on the correct side of the Lips. This is the moment the "beast wakes up."
• Crosses (exit) — price closed on the other side of the Teeth; the trend is considered broken. Williams' classic stop.

Alerts

Buy, Sell, Exit Long, Exit Short and "Alligator fell asleep" — connect any of them through the standard alert menu.

Settings

• Length and offset of all three lines, price source.
• Sleep threshold — how far the lines must separate (in % of price) for the phase to count as a trend. Rough guides: crypto 0.5–1%, forex 0.1–0.3%, stocks 0.3–0.5%. Tune it to your instrument and timeframe.
• Toggles for signals, background, table, fractals and the validity filter.
