Parabolic SAR
Parabolic SAR (Stop and Reverse) is a technical analysis indicator used primarily by traders to determine potential reversal points in the price direction of an asset. It was developed by J. Welles Wilder, who introduced it in his 1978 book, “New Concepts in Technical Trading Systems.”
The Parabolic SAR is represented by a series of dots that appear either above or below the price chart. These dots move dynamically based on price action and help traders identify the direction in which the asset’s price is trending and potential points where the trend may reverse.
Here’s how the Parabolic SAR works:
- When the dots are below the price, it indicates an uptrend.
- When the dots are above the price, it indicates a downtrend.
The rate at which the dots move depends on the acceleration factor (AF), which is a parameter in the Parabolic SAR formula. The AF starts with a small value and then increases progressively as the trend continues, which causes the dots to converge with the price. This feature allows the indicator to trail the price action and potentially provide signals for reversals.
How to use Parabolic SAR to buy and sell:
- Trend identification: The first step is to determine the prevailing trend direction based on the position of the Parabolic SAR dots in relation to the price. If the dots are below the price, it’s an uptrend, and if they are above, it’s a downtrend.
- Entry signals: For buying (going long), traders typically wait for the Parabolic SAR dots to move below the price, indicating a potential reversal from a downtrend to an uptrend. Conversely, for selling (going short), traders wait for the dots to move above the price, indicating a potential reversal from an uptrend to a downtrend.
- Exit signals: Traders can use Parabolic SAR to set stop-loss orders. In an uptrend, the SAR dots will serve as dynamic support levels, and in a downtrend, they will function as dynamic resistance levels. If the price crosses the SAR dots, it may signal a potential trend reversal, and traders may decide to exit their positions.
- Trend continuation: Some traders also use Parabolic SAR to stay with the prevailing trend until the dots are overtaken by the price, indicating a potential trend reversal.
However, it’s essential to remember that no single indicator should be relied upon exclusively for trading decisions. It’s best to use Parabolic SAR in conjunction with other technical analysis tools and consider fundamental factors to make informed trading choices. Additionally, like any technical indicator, Parabolic SAR is not foolproof and may provide false signals, so risk management is crucial when using it in your trading strategy.
