The first PSAR is used for opening positions and a faster PSAR is used for closing positions. This will book the profit quickly before the longer trend reverses. When the price closes above both PSARs, a buy position is opened. And when the price closes below the second PSAR, the position is closed. Opposite conditions are used for opening Sell Position. The PSAR auto trader applies a stop loss based on ATR, and a trailing stoploss.
