Parabolic SAR - Does it repaint?

Hi,

I know I probably can find the answer myself during a trading day. But it's more than 24 hours for the market to open and I'm so curious to know this.

Parabolic SAR seems like a very good indicator if used appropriately. I will consider PSAR only after a candlestick finishes. So it doesn't matter if the PSAR moved down-to-up or vice versa while a candlestick is yet to close. But the PSAR should not change once the candlestick is closed.

Is that guaranteed to happen?

While searching online, I found this thread:

There, the guy who posted a chart showed that it repaints. But it did not repaint after a candlestick is finished. It repainted only when the candlestick was still moving. I don't mind such moves.

Regards,
Bhoopalan I.

Problem is stop running, SAR won´t survive, even if it does not repaint.The smaller the time frame, they will either hunt your entry stop, or your trailing stop.(SAR).
Algorythms are programed specifically to do so.
You need to ask the question, where is the next trap?...in the beginning of the trade and during it, (if you survive the beginning.)

It does not repaint.

Most people that think indicators repaint, simply do not understand basic program logic.

I refer you to , "New Concepts In Technical Trading Systems", by J. Wells Wilder Jr. (the creator of SAR), he states, "The AF is increased by .02 each day that a new high is made".

When your software is computing the SAR it uses the LAST HIGH traded until the interval is finished. At that point the LAST HIGH is the definitive high. Clearly, when an interval is forming, it can have multiple LAST HIGHS.

Many indicators use the close as a variable. Here again, the software will compute the LAST PRICE as if it is the close until the interval ends and the close is definitive.

The version of the indicator you are using may have an option for "close only". This will cause the indicator to only update at the end of the interval. You would therefore not see the "repainting"(read continuous calculation) as the interval is created.

I'm sorry. The discussion is not about SAR is worth an attempt or not. Every trader has his/her style. It is just that whether it will repaint. Thanks for your reply.

Thanks. I'll check that book.

Dear Bhoopalan,
It depends on settings. The standard one draws a dot above current candle, and if you watch when it gets hit by the candle, it will jump to the other side and make a new line of dots starting from the bottom. If you use the one for previous bar close (non lagging shifted - maybe called 'non lag dot' or something like that idk), you will always be 1 period in lag as it will use the last bar close the way I understand it (please correct me if I am wrong).
Why not observe it for your self by running up a trade simulator, drag in PSAR indi and watch what happens. You can even directly test the indi without a simulator, just change from expert to Indicator in MT4 strategy tester (Ctrl+R) and select PSAR I think.

Kind Regards,
Tzamo

Thanks, tzamo. Not sure how to use either strategy tester or simulator. I'll google them.

I don't consider where the SAR is until the candle closes. So I rule out this possibility. I want to know if the SAR might change position even after sometime after close of a candle.

I think what you want to know is if PSAR dots repaints after they are plotted on the chart.

The answer is no it wont repaint, once a bar/candle is closed & the PSAR is plotted on the chart it will remain there, even if you change timeframe or close the chart. If a PSAR dot is plotted after a candle close it will remain there, no repaint.

Good luck.
How big can you think!

Exactly what I wanted to know. Thanks, Aar.

I don't know if anyone will see this but on the off chance it is seen, can PSAR repaint mid bar?

To my understanding PSAR puts a dot above or below the bar on bar open and it does not repaint until a new bar opens. Does this mean that PSAR is constant mid bar or does it repaint in the background that an EA might detect?
