Parabolic SAR

When it comes to trading, staying ahead of the game requires a good understanding of various technical indicators. One such indicator is the Parabolic SAR (Stop and Reverse), often referred to as simply SAR. In this article, we will delve into what Parabolic SAR is, how it works, and its significance in the world of trading.

What is Parabolic SAR?

At its core, the Parabolic SAR is a technical analysis indicator used to provide potential entry and exit points in a trading market. It was developed by J. Welles Wilder and is especially popular among traders in the stock and forex markets.

How Does It Work?

The Parabolic SAR indicator is primarily utilized to determine the direction of an asset’s price movement and identify potential reversals. It does this by plotting a series of dots either above or below the price chart, indicating the potential direction of the trend. If the dots are below the price, it suggests an upward trend, while dots above the price indicate a downward trend.

Here’s a basic formula to calculate the SAR:

SAR = SAR(previous) + AF × (EP(previous) - SAR(previous))
  • SAR(previous): Previous period’s SAR value
  • AF (Acceleration Factor): A multiplier that increases as the trend continues.
  • EP (Extreme Point): The highest high or lowest low during the current trend.

Significance in Trading

The Parabolic SAR can be a valuable tool for traders for several reasons:

  1. Trend Identification: SAR helps traders identify the prevailing trend quickly. This is essential for traders who follow trend-following strategies.
  2. Stop-Loss Placement: SAR provides an effective way to set stop-loss orders, helping traders manage risk more efficiently.
  3. Reversal Points: The indicator’s name, “Stop and Reverse,” highlights its ability to signal potential trend reversals. When the dots flip from above to below the price, it can be a sign to exit a long position and potentially enter a short one, and vice versa.
  4. Visual Representation: The visual representation of SAR through dots on a chart makes it easy for traders to grasp market trends intuitively.

Using Parabolic SAR Effectively

To use Parabolic SAR effectively, traders should consider the following tips:

  • Combine it with other indicators for confirmation.
  • Use it in conjunction with solid risk management strategies.
  • Be cautious during sideways or consolidating markets, as SAR might produce false signals.
  • Adjust the Acceleration Factor based on market volatility.


In conclusion, the Parabolic SAR (Stop and Reverse) is a powerful tool in a trader’s toolkit. Its ability to identify trends, set stop-loss levels, and signal potential reversals makes it a valuable asset. However, like any technical indicator, it should be used in conjunction with other analysis methods and with careful consideration of market conditions.

By mastering the Parabolic SAR and its nuances, traders can gain an edge in navigating the dynamic world of financial markets.

So, whether you are a novice trader looking to enhance your skills or an experienced one seeking to refine your strategy, incorporating Parabolic SAR into your toolkit is a step in the right direction.
