Parabolic SAR: Points of the Trend

The Parabolic SAR is the technical indicator used by traders to predict the trend direction along with entry and exit points. Although it provides easy-to-read signals, it hides many pitfalls that should be considered when trading. Let's define when you should use this technical tool.

What Is a Parabolic SAR Indicator

Parabolic SAR (PSAR) is a technical tool used by traders worldwide that reflects the security's direction. SAR stands for stop and reversal. The indicator is widely used to show the current trend, signal a market reversal, providing entry and exit points.

Parabolic SAR is a technical tool that reflects the asset's direction.

Welles Wilder Jr. created this instrument. If you are familiar with the RSI (Relative Strength Index) indicator, you’ve heard this name for sure. The RSI is one of the easiest, most widely used indicators. This fact should persuade you to keep reading about the PSAR indicator.

How to Recognize Parabolic SAR

PSAR consists of dots that move in the price direction. As it's a trend indicator, it is located on the price chart, not in the window below. If there is a bearish trend, the dots are above the candlesticks and move downwards. Imagine they put pressure on the price, forcing it to move down. If the trend is bullish, dots are below the candles and move up. To remember that, imagine dots support the price, pushing it upwards.

How to Set Up Parabolic SAR in MT4

Parabolic SAR is a standard tool in the MetaTrader platform. It means you can quickly implement it on your price chart without additional downloads.

Click "Insert" in the upper panel of the trading platform, then "Indicators." Choose "Trend"; and the Parabolic SAR will be on the list.

Set up

The indicator has only two settings. These are step and maximum. Their default values are 0.02 and 0.2, respectively. A step is the size of the acceleration factor. The acceleration factor starts with this value and then increases by the step size with each new high for an uptrend (or low for a downtrend), up to the amount defined by the “maximum” parameter.

PSAR settings

You can try other parameters for the indicator, but the standard ones suit basic trading strategies best.

Parabolic SAR Formula

Although the indicator is set automatically, to understand how it works, you should know the Parabolic stop and reverse formula.

The indicator is set automatically and has a perfect default setting that will suit any trading strategy.

To get the uptrend's dots, you need to subtract the prior Parabolic SAR from the prior extremum (higher high in the uptrend and lower low in the downtrend). The result should be multiplied by the previous acceleration factor (the standard is 0.02, which rises each time a new extremum forms by 0.02, maximum is 0.20). The result should then be summed with the prior Parabolic SAR.

Parabolic SAR = Prior Parabolic SAR + Prior acceleration factor (Prior extremum - Prior Parabolic SAR)

For the downtrend, the formula looks similar. However, you need to extract the prior extremum from the prior PSAR indicator. The result should be multiplied by the preceding acceleration factor. Another difference is that you need to subtract the result from the prior parabolic SAR, not find their sum.

Parabolic SAR = Prior Parabolic SAR - Prior acceleration factor (Prior Parabolic SAR - Prior EP)

Reading Parabolic SAR

It's quite simple to read the signals of the Parabolic SAR indicator. As we said above, it is presented by dots that move either above or below the candlesticks.

There are three primary indicator signals. These are trend direction, trend reversal, and trailing stop loss.

Trend direction. The trend is confirmed as soon as the indicator forms three dots in the direction of the primary movement. It means you can open a position in the direction of the trend. Here, a crucial point is hidden. The indicator creates dots, regardless of whether the trend is strong. If, for instance, the market moves sideways, forming small swings, the indicator will provide plenty of fake signals. 

That's why we recommend:

  • Using the indicator for big timeframes. High timeframes will prevent you from lots of signals.
  • Combining Parabolic SAR. It's essential to combine the indicators to get stronger signals. Let's consider an example with Moving Average.
  • Trend reversal. It's also possible to use Parabolic SAR to define the reversal of the current trend. For that, you need to wait until the dots change their direction. If at least one dot is located opposite to the current ones, you should close the opened trade.
  • Trailing stop loss. Sometimes, the indicator is used as a trailing stop loss. You can follow the movement of the indicator, changing the location of the stop loss. The change in the indicator's direction will signal a position's close.

Combining Parabolic SAR

Let's consider signals of what indicators you can combine with the Parabolic SAR to get reliable alerts. The Parabolic SAR is a trend indicator that shows market reversals. Thus, you can implement the PSAR indicator along with oscillators that confirm the turn of the price. For example, the RSI and MACD indicators.

The Parabolic SAR tool can be easily combined with both trend indicators and oscillators.

Also, Parabolic SAR is widely used with Moving Averages. Moving Averages are applied to the chart to define the trend direction. Still, unlike the Parabolic SAR, it moves sideways when the market consolidates. Using both indicators together, you won't fall into the trap of the Parabolic SAR.

Forex Trading with Parabolic SAR Indicator

Let's consider a real example of Parabolic SAR trading. In the picture below, we have a strong uptrend of the asset, which means we should open a buy position (1). Take profit isn't determined in advance (2). We close the trade as soon as the indicator signals a downtrend.

Also, on one of the chart parts, you can see an example of the trailing stop loss (3). It can be moved in the direction of the uptrend.

Parabolic SAR: Benefits and Drawbacks

PSAR is not the basic indicator for trading strategies as it has some drawbacks. Check them to know to use the indicator effectively.



Simple. The tool has only two settings that suit all basic trading strategies.

Need to be confirmed. The indicator is not the most reliable tool you can use to define the trend direction. Still, using the indicator together with other instruments, you will get reliable entry and exit points.

Clear signals. The indicator provides clear signs that don't require specific knowledge to be read.

Rare in strategies. Although the PSAR indicator is one of the most accessible indicators, it's not as famous as MACD, Moving Averages, RSI, etc. 

Major signals. The indicator submits vital signs as the trend direction, reversal points, and trailing stop loss levels. 

Used only in strong trends. The indicator doesn't work well when the market consolidates. It may provide many fake signals. 

Smaller lag. Although all indicators have a time lag, as they are based on the previous price number, the Parabolic SAR tool has the smallest one. It reflects the price changes almost immediately, forming new dots.


Parabolic SAR: Your Perfect Strategy

If you still have doubts about applying the indicator to your trading, we offer a trading strategy that will help you get started. As we said above, Parabolic SAR works well with the moving average indicator.

Although the tool works well on high timeframes, in combination with moving averages, we can use smaller timeframes. For example, we will use a 30-minute chart of the EUR/USD pair, the most reliable asset for beginner traders. Moving averages should have a period of 20 and 40.

Step 1. Apply the Parabolic SAR indicator with standard settings and 20-, 40-period moving averages on the price chart.

Step 2. The cross of moving averages is the primary signal the indicator provides. We are considering the sell trade; thus, we need to find a dead cross. A dead cross is when a Moving Average with a smaller period crosses the one with a more significant period upside-down.

Step 3. We should get a confirmation from the Parabolic SAR. Previously, we said that the indicator reflects all ups and downs of the price chart. Even if the primary trend is bearish, the small swing up will be noticed by the indicator.

Step 4. As soon as the Parabolic SAR forms dots above the price chart, signaling the downtrend, we can move to the next step. Our next step is to open a sell trade at the candle's opening that follows the formation of the first dot above the candlesticks.

Step 5. Now, it's time to limit possible losses if the price changes its direction due to high volatility caused by unexpected fundamental factors. Stop loss may locate at 30-50 pips above the entry point. Still, it's vital to check previous support and resistance levels. Stop loss should be slightly above the resistance level.

Step 6. Let's take the profit as moving averages are more robust tools that the Parabolic SAR; we should follow their signals. Close your trade as soon as moving averages form a golden cross.

This was an example of the sell trade. Opposite rules apply to the buy trade.

Tip for Traders

Check the tips that will prevent you from making mistakes.

  • Fake dots. The most common mistake is that traders open trades any time the indicator forms dots. It leads to losses as Parabolic SAR doesn't reflect the sideway direction. Thus, the market creates small swings and changes its direction frequently as you don't have time to collect the potential profit.
  • Not enough dots. The standard rule is to open a trade as soon as there are at least three dots formed in one direction. Otherwise, there are risks of fake signals.
  • Wrong settings. It's recommended to use default settings as they provide the best step size that will neither create additional dots nor make significant lags.

Why Use a Parabolic SAR Indicator

Although the indicator has disadvantages, it is a default indicator in the MetaTrader platform. That means you should apply it to your trading strategies. There are several reasons why you should use the Parabolic SAR tool. These are:

  • Easy to use. The indicator provides simple signals and doesn't require special knowledge to use it.
  • Easy to combine. Another key benefit of the indicator is that you can easily combine it with other tools that provide the same signal – trend reversal.
  • Easy to set. Unlike most indicators, Parabolic SAR doesn't require changing the settings. Use the default settings to get signals.


To conclude, the Parabolic SAR indicator is one of the easy-to-use tools, especially for beginner traders. Nevertheless, it provides plenty of fake signals if you use it without confirmation and for sideways movements.
