Parabolic SAR indicator definition

Parabolic SAR indicator

Created by Welles Wilder, who authored the RSI indicator, the PSAR indicator is considered one of the core indicators for technical analysis software.

The Parabolic SAR (PSAR) indicator is used to monitor the trend of the asset’s rising/falling trend and also forecasts the price reversal. Although the accuracy is not good because of its simplicity, the combination of other indicators and PSAR is essential for a trader regardless of profession or newbie.

Description of PSAR indicator

The PSAR indicator is shown as a line below the chart or lines above the chart, interrupted repetitively. When above, the line tends to go down, the price of the trend is down too. Conversely, when below, the line tends to go up, prices tend to rise.

Parabolic SAR indicates the power of increasing and decreasing of asset prices in current time

How to calculate the PSAR indicator

PSAR (n) = PSAR (n-1) + AF * (EP – PSAR (n))

WHERE:

PSAR (n) is the value of the current PSAR
PSAR (n-1) is the value of the previous PSAR
EP (Extreme Price) is the culmination of a trend. For example, the EP will be the highest price of an uptrend and be the lowest price of the downtrend.
AF (Acceleration Factor) is the acceleration constant of the PSAR formula. Within the range of 0.02 to 0.20. Every time a new EP peak is obtained, the AF will increase to 0.02 to a maximum of 0.20.

Parabolic SAR indicator entry signal

PSAR is weak

When the PSAR line shows signs of a horizontal line, it is difficult to reverse the price.

Parabolic SAR signals with a steady line predict no sudden change

PSAR reversed sharply

Signals when the Parabolic SAR indicator is rising or down steadily, suddenly reversing to the opposite by 2-3 points with a sharp slope, this is a signal that announces prices will reverse.

Combine the Support / Resistance indicator

The PSAR indicator will work well with the Support / Resistance lines to increase accuracy. If captured well, just 2 indicators and feeling into your luck, you can make money better.

It is good that PSAR tends to fall while staying under the resistance line, which is a good sign that the price will fall.

And vice versa, when PSAR tends to rise while it is on the support line, it is a signal that prices will rise.

Create compound indicators

A combination of DeMarker, RSI, Bollinger Bands, or any other simple indicators brings higher accuracy. If you are new, at this level you will understand the trend when using simple indicators at the same time. When you are already professional, you will combine the advanced indicators.

Note

PSAR is a pocket indicator, but it only works when opening positions for a long time. If you are dealing with a short time frame, consider running with more indicators than usual to increase accuracy. Although more indicators mean you have to have more analytical skills.
