ParabolicSAR

[ronaldgreene828]

Hello,
If I use several different settings for the 3 parameters of the ParabolicSAR indicator, does this create more than a single series?

Hello ronaldgreene828,

Thank you for the post.

This question did not seem to relate to the thread you originally posted in so I created a new thread for your questions.

Are you asking if changing the parameters adds some kind of secondary data when using this indicator?

What series are you referring to here?



I look forward to being of further assistance.

I'm using the parabolicSARS indicator using 5 different settings combinations in one strategy for entries and exits. I noticed that the following was created at the start of OnBarUpdate:

if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 5)
return;

I searched for information and after reading the other thread, I wondered if this is necessary or incorrect.

Hello ronaldgreene828,

Thank you for your post.

The Strategy Builder correctly adds the checks for BarsInProgress and CurrentBars to prevent the script from calling more than 5 bars ago until there are at least 5 bars of data processed, to prevent an index error.

In a multi-bars script, the OnBarUpdate() method is called for each Bars object of a script. For a single Bars script, this property will always return an index value of 0 representing the primary Bars and instrument the script is running on.

Here is a help guide link with more information about BarsInProgress - https://ninjatrader.com/support/help...inprogress.htm

CurrentBars contains the values representing the number of the current bars in a Bars object. The CurrentBars check is used to make sure that there are enough bars processed before executing the rest of your script. For example, if(CurrentBars[0] < 5) return; checks to see if there are at least 5 bars processed for the primary bars series. If there are less than 5 bars, the script will return (end).
