What is SMMA?
The Smoothed Moving Average uses a very long effective memory, so it moves more slowly than an SMA of the same length. It is the average used by the Williams Alligator.
SMMA formula
| Output | Calculation |
|---|---|
| SMMA | (previous SMMA × (n − 1) + close) ÷ n |
How to read SMMA in your code
| Signal | Meaning | Condition |
|---|---|---|
| Price above average | Bullish bias | Close above value |
| Price below average | Bearish bias | Close below value |
| Slope | Direction of the trend | Latest value versus the previous one |
Limitations: Slow response means late signals after reversals. Nothing on this page is financial advice.
Compare the last two closed SMMA values
Use backtrack=1 to skip the candle still forming, and results=2 to compare the last two closed candles. Arrays run oldest first.

}SMMA API FAQ
What does the SMMA API return?
It returns value, plus a timestamp for the request. Results are JSON.
Is the latest SMMA value final?
No. The newest value belongs to the candle still forming and can change until it closes. Add backtrack=1 to read the last closed candle.
Which SMMA settings can I change?
You can set period. See the parameters table above for defaults.
Can I get SMMA for US stocks?
Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
