Parabolic SAR

Parabolic SAR indicator, based on Welles Wilder's Parabolic Time/Price Strategy, plots a parabolic curve taking into consideration the market's price and time relations.

During the calculation, the parabolic curve crosses over and under the price. When the parabolic curve goes below the current prices the market is considered bullish, and when the curve crosses above the current prices, it may indicate a down trend.

The Parabolic SAR indicator determines stop and reverse (SAR) points and may be used to define when the position should be reversed and a trade in the opposite direction should be taken.
