Parabolic SAR is a good trend following indicator which strictly follows price.
SAR usually works like a trailing stop loss on the price chart.
In an uptrend, the SAR dots remains below the price and rises as long as the uptrend remains in place.

Once price stops going up and reverses below the SAR dots, it marks the beginning of a downtrend. Basically, in a downtrend, the SAR dots continue to remain above the price.
Some of the traders even put their stop-loss based on SAR dots.
