The Parabolic SAR indicator (PSAR) was invented by Welles Wilder and presented in his 1978 book, “New Concepts in Technical Trading System.” Wilder called the PSAR the “Parabolic Time / Price System,” where SAR stands for “stop and reverse.” The PSAR indicator forms a parabola that is either above or below price. When price is above the indicator, it acts as support / a trailing stop and indicates a bullish market. When price is below the indicator, it acts as resistance / a trailing stop and indicates a bearish market. When the indicator is in a down trend (price is below the Parabolic SAR), the indicator level can be used as a reversal level.
