Parabolic SAR is a trend-following indicator that helps traders identify the direction of a trend and potential reversal points.
Why Is It Called Stop and Reverse?

- Exit a trade when the trend weakens
- Reverse the trading direction when a new trend starts

How Parabolic SAR Works

Parabolic SAR Formula
The basic formula is:
SARnext​=SARcurrent​+AF(EP−SARcurrent​)
Where:
- SAR = Stop and Reverse value
- AF = Acceleration Factor
- EP = Extreme Point
What Is Acceleration Factor (AF)?
Acceleration Factor determines:
- Indicator sensitivity
Default values:
- Starting AF = 0.02
- Maximum AF = 0.20
Higher AF:
- Faster signals
- More false signals
Lower AF:
- Slower signals

Extreme Point represents:
- Highest high during uptrend
- Lowest low during downtrend
Default Parabolic SAR Settings
