What is the Williams Alligator API?
The Williams Alligator uses three smoothed moving averages — Jaw (13-period, shifted 8), Teeth (8-period, shifted 5), and Lips (5-period, shifted 3) — to identify trend direction and strength. When the lines are intertwined, the market is ranging (sleeping). When the Lips cross above Teeth and Jaw, the alligator's mouth opens upward — a bullish trend signal. Our API delivers all three values in a single call so your bot can determine market state instantly.

Frequently Asked Questions
What are the exact parameters for each Alligator line?
Jaw: 13-period SMMA shifted 8 bars forward. Teeth: 8-period SMMA shifted 5 bars forward. Lips: 5-period SMMA shifted 3 bars forward. These are Bill Williams' original settings as used industry-wide.
How do I detect when the Alligator is 'sleeping'?
The lines will be close together or intertwined. The API returns a signal value of 'sleeping' when the spread between all three lines is below a threshold — no additional comparison needed in your code.
Can I get historical Alligator values for backtesting?
Yes — use GET /v1/indicator/history with indicator=Alligator. The response includes all three line values per bar, making it straightforward to replay Alligator states over any historical period.
Is the Alligator useful for AI market analysis?
Yes. The three numeric values and signal classification are ideal for AI prompts. Pass the values to a ChatGPT Custom GPT or Claude Tool and let the model reason about trend state, entry timing, and trade management in context.
