Is it possible to add options to change color size and style of the dot please?
Adding alert would be great too if possible.

Thanks in advance.
Check in this thread, there are some mtf correctly done parabolic sar's in here. The built in mt4 version has some calculation errors.

PSAR (Parabolic SAR - Parabolic Stop And Reverse) Indicators for Metatrader 4

Parabolic SAR Indicators Metatrader 4.png
Example: Parabolic SAR shown on a ProRealTime Chart

Parabolic SAR (SAR) is a time and price technical analysis tool primarily used to identify points of potential stops and reverses. In fact, the SAR in Parabolic SAR stands for "Stop and Reverse". The indicator's calculations create a parabola which is located below price during a Bullish Trend and above Price during a Bearish Trend.


J. Welles Wilder created the Parabolic SAR (SAR) and featured it in his book New Concepts in Technical Trading Systems. The book was published in 1978 and also featured several of his now classic indicators such as; The Relative Strength Index, Average True Range and the Directional Movement Index. Much like the indicators mentioned, the Parabolic SAR indicator is still widely used and has great importance in the world of technical analysis.


  • Previous SAR = The SAR value for the previous period.
  • Extreme Point (EP) = The highest high of the current uptrend or the lowest low of the current downtrend.
  • Acceleration Factor (AF) = Determines the sensitivity of the SAR. 
  • AF starts at .02 and increases by .02 every time the EP rises in a Rising SAR or EP falls in a Falling SAR.

The calculations for Rising Parabolic SAR and Falling Parabolic SAR are different so they will be separated.

Rising Parabolic SAR

Previous SAR + Previous AF (Previous EP + Previous SAR) = Current SAR

Falling Parabolic SAR

Previous SAR - Previous AF (Previous SAR - Previous EP) = Current SAR


Parabolic SAR creates a parabola on the chart. The parabola is always below price in an uptrend and above price in a downtrend.

One aspect to consider is the Acceleration Factor (AF) that was mentioned in the calculation. The AF, which moves in user defined increments, is a value which will alter the sensitivity of the SAR. The AF is a multiplier which affects the rate-of-change of the SAR. AF increases as the trend continues in the same direction, until it reaches its maximum (usually .20). The lower the AF, the further away it is from price, therefore it is less likely to signal a stop or reversal. Decreasing the AF increments, decreases the sensitivity of the SAR while increasing it, increases the SAR's sensitivity. 


Stops and Reversals

The Parabolic SAR (SAR) indicator has a very simple premise. When price in an uptrend breaks below the parabola (which will be below the trend), this signals a potential reversal of price. When price breaks above the parabola (above the trend) during a downtrend, this can also signal a price reversal.

In a practical sense, many traders use these breakthroughs as a point to place stop orders or even as points to enter the market at the beginning of a new trend.


Parabolic SAR is a nice, compact indicator that can provide some good information. It is not typically recommended, however to use it as a stand-alone to generate trading signals. Since it is time and price based it is not adept at measuring the actual strength of a trend, merely its direction and duration. It is a good idea to use it in conjunction with an indicator that specializes in measuring trend strength. A good choice would be Wilder's Directional Movement (Wilder's DMI).

This is a correct version of parabolic sar.

would you be so kind to create a PSAR trendline.

the idea is to connect the onset dot to the current dot of same trend (with a trendline), as the candle breaks the trendline,
TL retains its print. giving a better visual than the normal psar (as the breakout is seen right away). many thanks sir.

*also an option to hide the dots if can
hello mr tools
this is a very interesting idea can u please do look into this if this is possible or not ?
