Parabolic Sar
The parabolic SAR – or parabolic stop and reverse – is a technical indicator that is used to forecast potential reversals or continuations in an underlying market. A reversal can be a bullish market changing into a bearish market, or a bearish market changing into a bullish market, while continuations signify that a market will maintain its previous momentum. A trader can use the parabolic SAR to time their entry into a long or short position.
