What is Parabolic SAR?
The Parabolic SAR (Stop and Reverse) is a technical analysis indicator used to identify potential trend reversals and set trailing stop-loss orders. Developed by J. Welles Wilder Jr., it's plotted as a series of dots above or below the price, depending on the trend direction. It’s a popular choice for traders looking for clear visual signals and dynamic risk management tools. The indicator aims to capture significant portions of a trend while minimizing losses when the trend changes.
How it Works
Parabolic SAR calculates dots based on the price's recent high and low. During an uptrend, dots appear below the price; in a downtrend, they appear above. The indicator uses an acceleration factor, starting at 0.02 and increasing by 0.02 each time a new high (uptrend) or low (downtrend) is reached. This acceleration causes the SAR to move closer to the price as the trend matures, signaling increasing volatility.
Trading Signals
A key signal is when the price crosses the Parabolic SAR dots. If the price crosses *above* the dots, it suggests a potential buy signal, indicating a shift from a downtrend to an uptrend. Conversely, if the price crosses *below* the dots, it suggests a potential sell signal, indicating a shift from an uptrend to a downtrend. Traders often use this as a trigger to enter or exit positions.
Basic Settings
The primary settings are the Acceleration Factor (default 0.02) and the Maximum Acceleration Factor (default 0.20). A higher Acceleration Factor makes the indicator more sensitive to price changes, generating more frequent signals, but also potentially more false signals. The Maximum Acceleration Factor limits how quickly the indicator can accelerate. Experimentation is key to finding settings that suit your trading style and the specific asset you're trading.
