Parabolic SAR in analyzing trends

 Traders use the technical indicator known as the Parabolic SAR (Parabolic Stop and Reverse) to forecast the price movement of stocks. The renowned technical analyst and creator of the 1978 best-seller New Concepts in Technical Trading Systems, Welles Wilder, was responsible for its creation. Parabolic SAR is “a trend following indicator that is designed to identify a decisive change in the market’s direction,” according to Wilder in his book.

Parabolic SAR in analyzing trends

Basically, the Parabolic SAR plots a series of points above or below the price of a security depending on the trend of that security. A series of .s will appear below the price when it is rising, and above it when the price is falling. By indicating when to enter and exit positions, it also aids in the creation of buy and sell signals.

The indicator is made up of a grid of moving .s that react to changes in stock price. Starting at the end of the current trend, the .s are positioned. The indicator’s .s move in the opposite direction of the trend when the indicator’s moving averages flip, indicating a possibility that the security will turn around.

The Parabolic SAR’s Functions

For tracking price changes, the Parabolic SAR also employs an acceleration factor. The distance between the .s widens as the acceleration factor rises. This shows that the price of the security is moving quickly in the trend’s favor. The .s get closer together as the acceleration factor drops, which shows that the security is turning around.

The Parabolic SAR’s main objective is to reveal the trend’s direction and pinpoint potential entry and exit points. In order to aid in decision-making, many traders also combine it with other indicators.

Benefits of parabolic SAR

A technical analysis tool used to examine and forecast price movements in securities is the Parabolic Stop and Reverse (SAR) Indicator. Although it can be used to determine support and resistance levels, its primary use is in momentum trading strategies.

Exponential moving averages (EMAs) serve as the foundation for the Parabolic SAR indicator. Placement of points of reference above or below the price or EMAs of a security results in the formation of a parabola. The SAR indicator points will move to maintain their position in relation to the security’s price as the security’s price changes.

Determine Exit and Entry Point

Determine entry and exit points for a particular security using the parabolic SAR indicator. When the SAR indicator is below the indicated resistance level and the security’s price is in an uptrend, it can be used to enter a trade. On the other hand, it can be used to enter a trade if the security’s price is falling and the SAR indicator is above the designated support level.

Exit points are also chosen using the Parabolic SAR indicator. Similar to entry points, the SAR indicator can be used to close out a trade if it is above or below the indicated support or resistance level. The trade needs to be stopped as soon as the security’s price crosses the level shown.

The PAR indicator’s simplicity is one of its main advantages. It is a simple-to-use indicator that can be applied to find exit points as well as profitable trading opportunities. As long as the security’s price follows the parabola, it is also reasonably accurate.

Recognize The Resistance And The Support.

Finding support and resistance levels is another application for the Parabolic SAR indicator. The price of the security is likely to become volatile at this level and the security may reverse if the SAR is placed above the indicated resistance level. Similar to this, if the SAR is placed below the indicated support level, it may be a sign that the price of the security may become volatile, possibly leading to a reversal.

The Parabolic SAR indicator is a flexible technical analysis tool that is straightforward and accurate. It can be used to enter and exit trades, find levels of support and resistance, and spot potential reversals.

Disadvantages Of Parabolic SAR.

Even though the Parabolic SAR is a useful tool, it’s important to keep in mind that it has a number of limitations that should be considered before using the indicator to make trading decisions.

Lagging Indicator

Because the Parabolic SAR is a lagging indicator rather than a predictive signal, it always follows price movement. Due to the indicator’s propensity to give false signals and constant “pursuit” of the price, this lag can be problematic. As an illustration, the indicator might indicate a reversal that is perilously close to a significant support or resistance level, only for the security to bounce off that level and continue its current trend. Retail traders frequently lose out on the move they were anticipating as a result of this “false alarm.”.

Not Recommended For Markets That Are Strongly Trending Up Or Down

Markets that are strongly trending tend to move in one direction with few significant reversals, and the indicator is intended to determine when a security is likely to make a sharp reversal. These price changes can easily confuse the Parabolic SAR, causing it to give false signals or show no movement as a result of the indicator’s failure to adapt to the shifting market environment.

False Signal in Range-Bound Market

Since range-bound markets frequently move sideways over time, the indicator may produce a number of signals as the price moves up and down the range. This can be a problem because it might be challenging to determine which signals are meaningful and, consequently, less helpful to a trader’s strategy.

And finally, because the Parabolic SAR is a trend-following indicator, it will only spot potential turning points after the current trend has already been established. This can be a drawback for those looking to spot a trend before it has begun because the indicator frequently gives a signal at the exact moment the trend is coming to an end.


The Parabolic SAR is a helpful tool that can give traders and investors a better understanding of the dynamics of price movement. It shouldn’t be the only source of information used, though, because of its limitations, when making investment decisions. Instead, it ought to be applied in conjunction with other types of technical and fundamental analysis to offer the best trading insight.
