The Parabolic Time/Price System, developed by Welles Wilder, is used to set trailing price stops and is usually referred to as the 'SAR' (stop-and-reversal). It is an indicator that is a very useful and accurate tool during a trending period. Parabolic SAR should only be employed in trending markets - when it provides excellent entry and exit points.

The Parabolic SAR provides excellent exit points. You should close long positions when the price falls below the SAR and close short positions when the price rises above the SAR.
If long (i.e., the price is above the SAR), the SAR will move up every period, regardless of the direction the price is moving. The amount the SAR moves up depends on the amount that prices move.
