Dots that form below the price and are rising in an upwardly sloping pattern signals an uptrend.
Whereas, the dots that form above price and are falling in a downwardly sloping pattern signals a downtrend.
Calculation of Parabolic SAR:
The Parabolic SAR (PSAR) indicator uses the recent extreme price (EP) with an acceleration factor (AF) for determining where the indicator dots will appear.
It is calculated as follows:
- Uptrend: PSAR = Prior PSAR + Prior AF (Prior EP – Prior PSAR)
- Downtrend: PSAR = Prior PSAR – Prior AF (Prior PSAR – Prior EP), Where:
- EP = Highest high for an uptrend and lowest low for a downtrend, updated each time a new EP is reached.
- AF = Default of 0.02, increasing by 0.02 each time a new EP is reached, with a maximum of 0.20.
This calculation creates a dot that can be connected with a line, below the rising price or above the falling price.
The dots are always present; this is why this indicator is also known as “stop and reverse.”
How to use this Indicator?
The Parabolic SAR performs well in the trending markets.
In the consolidating markets, the parabolic SAR tends to whipsaw back and forth, and thus generate false trading signals
The main use of this indicator is to buy when the dots move below the price bars that signals an uptrend.
And sell when the dots move above the price bars signaling a downtrend.
From the Daily chart of Reliance Industries Ltd. below, we can see that how in the consolidating market the parabolic SAR tends to whipsaw back and forth, and thus generate false trading signals.
Whereas in the trending markets, it is giving a clear signal of buy and sell.
One should short the stock when the dots turn above the price which signals that the trend is going to reverse in the downtrend as shown above.
One should buy it when the dots turn below the prices, indicating the trend is going to reverse in the uptrend.
Indicators that compliment PSAR:
Traders can use other indicators like the average directional index momentum indicator for confirming the strength of the existing trend.
Pros and Cons of Parabolic SAR:
The main benefit of this indicator is that, during a strong trend, the indicator highlights that the trader should keep holding his position.
The indicator also gives an exit when there is a move against the trend, which signals a reversal.
Traders can also generate powerful trading signals using Parabolic SAR and RSI.
The main drawback of this indicator is that it doesn’t provide good trade signals during sideways market conditions.
Without a clear trend, the indicator constantly flip-flops above and below the price.
