Parabolic Stop and Reverse (psar)
Parabolic Stop and Reverse (PSAR) was developed by J. Wells Wilder, that is used to determine trend direction and it’s potential reversals in price. PSAR uses a trailing stop and reverse method called “SAR,” or stop and reverse, to identify possible entries and exits. It is also known as SAR.
PSAR indicator typically appears on a chart as a series of dots, either above or below an asset’s price, depending on the direction the price is moving. A dot is placed below the price when it is trending upward, and above the price when it is trending downward.
