What is the Parabolic Stop and Reverse Indicator?

In trading, indicators are a tool to predict the market’s direction. They can also help traders determine when to buy and sell and how much a tradable asset is likely to move. This advancement in the field of trading uses patterns, including support and resistance levels, to more efficiently identify and confirm trades.

What is Parabolic SAR

The parabolic stop and reverse indicator, or PSAR, is an advanced candlestick-based indicator that indicates the price trend. It uses the color green to indicate when prices are rising and red to indicate when prices are falling. The indicator uses green and red candlesticks to show the maximum and minimum volume levels during the current trading session. The use of PSAR indicators is relatively simple. These indicators are used to confirm or deny price trends over time. When the indicator is in a confirmed position, it indicates the price trend is likely to continue. When the indicator moves into a different position, it suggests that the price trend has changed and may reverse

Origin of the Parabolic SAR

The Parabolic SAR indicator was developed by J. Welles Wilder, an American mathematician. The indicator’s name is derived from the parabolic shape of its plotline, highlighting the most significant price movement in a security. The indicator was first published in the 1970s.

How the PSAR Works

The Parabolic SAR has one line that is always drawn. The line represents the price action and shows green when prices are rising and red when prices fall. Each position shown on the chart is drawn in a box and shows the opening price, the high, and the low. The candlestick represents when the price closed relative to those levels. This helps traders identify areas of support or resistance.

Interpretation of PSAR

The PSAR indicator is a simplified version of the engulfing bar pattern and the candlestick chart, which are widely used in technical analysis. The reason is it eliminates the influence of the previous day’s price action on the current candle. The PSAR can be used as a trading signal, but it should not be used to enter and exit trades. Instead, it can be used as an aid to avoid placing a trade in the wrong direction. The PSAR can help determine whether the current trend is strong or weak by looking at the strength of support and resistance levels over time.

Where to Find the PSAR

The PSAR is usually found on graphics software platforms and can be customized to fit the trader’s desired settings. It can also be found in stock market analysis, swing trading articles, or publications, but retail traders do not commonly use it.

How to Trade with PSAR

The color of the current candlestick is used to place buy and sell stop orders. When the price action is green and rising, a buy stop order can be placed above the most recent high. When the price action is red and falling, a sell stop order can be placed below the most recent low. These orders can be adjusted as desired.

How to Identify an Invalid PSAR Quote

One way to identify an invalid PSAR input is the price does not go through all the required price ranges for the indicator to be considered valid. This can happen when the price is being held at a certain level to prevent prices from showing an entirely green or red candlestick.

A quote that begins as red, switches to green, and ends up as red again indicates a reversed PSAR input and is invalid.

What To Do When You Get An Invalid PSAR Quote

One response to receiving an invalid PSAR input is to wait until the next trading day. The price action can remain within the specific price range of the indicator, which may then be considered valid. Another reason to wait is to allow time for the latest price action to be presented. It is important to take a close look at the PSAR input and how it was obtained in either case. If the price remains within the required range, it may be valid. If not, then look for a reason to question the input.

How To Calculate PSAR

To calculate the PSAR indicator, first add the current candle’s highest price and the lowest price. Then, take a percentage of that number and add it to the opening price. The final number represents the PSAR indicator line.


The PSAR is an excellent tool to evaluate price movements efficiently. It allows traders to monitor market activity. It also helps traders identify support and resistance levels in the market and predict future price movements. Additionally, the indicator can be consulted to determine whether the market’s direction is favorable to generate market gains.


The PSAR generates a lot of data, leading to analysis paralysis. Traders need to ensure that they are following the indicator properly. Finally, the PSAR can also be a source of misinterpretation, as false signals can appear as support and resistance levels can overlap.
Some traders believe that the PSAR does not work because it does not show support and resistance levels. However, Wilder did publish a book, “Prices Are Moving: On the Market’s Rhythms,” which indicated the use of PSAR and other candlestick patterns. Therefore, it can be assumed that PSAR is reliable and accurate.

PSAR and Blockchain

Although the indicator was developed in the 1970s, the PSAR is still relevant and useful today. The indicator can be applied to blockchain technology and cryptocurrency markets. A developer can create an app that scans cryptocurrency market data with the PSAR including predicting volatility and future price movements. Furthermore, the indicator can be used to predict trends between various cryptocurrencies.


Technical analysis is a popular tool used by traders to generate trading signals. Indicators and patterns such as the PSAR indicator can provide a valuable tool for making informed decisions about trading securities. The PSAR is a useful indicator for traders because it helps identify support and resistance levels in the market. The indicator is relatively simple to understand and can help traders set buy and sell stop orders.
