PSAR or Parabolic SAR is an indicator to identify the trend and reversal. This indicator is plotted as a dot either above the Stock price or below it. SAR signifies Stop and Reverse, hence the PSAR dots continue to follow the trend and at potential reversal it changes its direction.

PSAR dots follows the price chart below the candles when an uptrend continues, and these dots reverses and gers plotted above the price chart when the downtrend continues.
