However, if the limit of 0.20 is reached, this value is maintained by the duration of that trade . Another thing to consider is the sensitivity of the indicator, which can be adjusted manually.

We shall know the importance of each term if we take the time to study, and this article focuses on the parabolic SAR. The parabolic SAR is among the popular indicators to predict short future movement. The indicator is highly valuable, as simple as the definition sounds.

Assuming the price dips under the parabolic SAR, leave the long exchange.

How is the Parabolic SAR Indicator used in trading?

The Parabolic SAR is best used in steadily trending markets. If the market is choppy or range-bound the trader will find himself whipsawed in and out of trades when using this indicator.

In a trending market solid trades with long-term profits are more likely.

A. Find the difference between the highest price made while in the trade and the SAR for that day. Multiply the difference by the AF (Acceleration Factor – determines the sensitivity of the SAR) and add the result to the current SAR to obtain the SAR for the next day. To find a sell or short point when the price moves below the dotted line, and the dots move above. If the time frame is small, Parabolic SAR will generate too many signals, and it might offer contradictory signals. On higher time frames, the trade will move slowly, and this will avoid false signals as most of the market noise is eliminated. The Parabolic SAR is best used when the market is trending; that is when the market has long rallies in either direction and have small corrections.

Calculation of Parabolic SAR

Again, the parabolic SAR determines the price direction and changes in the direction. Two crucial things are considered here “direction” and “change in direction.” An asset moves in a specific direction during a change, showing the impact of price on the asset. Thus, price is the main tracking factor in determining an asset’s direction and changes. And this is why it is called the “stop and reversal system.” The same price effect is applied to cryptocurrency.

  • Now it’s your turn to tweak the code and make it more close to the live environment.

According to him, the first SAR can be calculated based on the last EP before a market trend reversal. Some traders also use the Parabolic SAR indicator to determine dynamic stop-loss prices, so that their stops move along with the market trend. Such a technique is often referred to as trailing stop-loss. When a change in market momentum occurs, the dots will cross over from one side of the price bars to the other. Because changes in market momentum often precede changes in price, this flip is considered to be an indicator that a trend reversal is imminent.
