Parabolic SAR

Definition of the Parabolic SAR

The Parabolic SAR (Stop and Reverse) is a trend-following indicator used to set trailing stop-loss orders for both long and short trades. It appears on price charts as dots positioned either above or below the price of an asset. When the price is in an uptrend, the dots appear below the price, and when in a downtrend, the dots flutter above it. The main function of the Parabolic SAR is to help traders identify potential reversals and make informed trading decisions based on market trends.

Parabolic SAR vs Moving Average

Examples

• Uptrend: If the price of a stock is moving upward and the SAR dot appears below the price, the trend is likely to continue. For example, if the stock is showing a series of higher highs and higher lows, traders might use the Parabolic SAR as a trailing stop-loss.

• Downtrend: Conversely, if the price drops and the SAR dot moves above the price, it signals a potential downtrend. Such as when a stock is consistently showing lower highs; this is when some traders might decide it’s time to change direction in their investment strategy.

Formula for the Parabolic SAR Indicator

The Parabolic SAR is calculated using the following formula:

1. For each step:
   • If the trend is upward:
     • \( \text{SAR}{n} = \text{SAR}{n-1} + \text{AF} \times (\text{EP} - \text{SAR}_{n-1}) \)
   • If the trend is downward:
     • \( \text{SAR}{n} = \text{SAR}{n-1} + \text{AF} \times (\text{SAR}_{n-1} - \text{EP}) \)

Where:

• \( \text{SAR}_{n} \) = Current SAR value
• \( \text{SAR}_{n-1} \) = Previous SAR value
• \( \text{AF} \) = Acceleration Factor (usually starting at 0.02, can increase up to 0.2)
• \( \text{EP} \) = Extreme Point (highest price in an uptrend, lowest in a downtrend)
