What is Parabolic SAR?
Parabolic SAR (Stop and Reverse), developed by J. Welles Wilder, trails price with a stop level that accelerates as a trend extends. When price crosses it, the stop flips to the other side. The start, increment and maximum parameters control the acceleration.
Parabolic SAR formula
| Output | Calculation |
|---|---|
| Next SAR | SAR + AF × (extreme point − SAR) |
| AF | Starts at start, grows by increment on each new extreme, capped at maximum |
How to read Parabolic SAR in your code
| Signal | Meaning | Condition |
|---|---|---|
| Uptrend | Stop trailing below price | Close above value |
| Downtrend | Stop trailing above price | Close below value |
| Reversal | Stop flipped sides | Close crosses value |
Limitations: It is always in the market, so it whipsaws in ranges. Many traders only act on flips when ADX shows a trend. Nothing on this page is financial advice.
Compare the last two closed Parabolic SAR values
Use backtrack=1 to skip the candle still forming, and results=2 to compare the last two closed candles. Arrays run oldest first.
