What does VarName.Set(1, VarName[1]) do?

Hello All: What does this statement do?

VarName.Set(1, VarName[1])

Is the "1" an initialization value of some sort?

Thank you for any guidance you can provide.

The "1" is an index into an array called VarName.

VarName[1] means the element in the array which has index 1.

Xeno, thank you for your reply. This is from the attached Ninja script for the SuperTrend Indicator. I was refering to the first "1", in the line

VarName.Set(1, VarName[1]) (the [1] reference here is to "the value at prior bar")

There are no arrays defined as far as I can see. There are references of similar structure with a single dimension such as

VarName.Set(VarName[1]);

so to see the two arguments is throwing me off.

I am experienced in EL and am trying to convert from the NT script.

Thank you for again for your attention.

This is referencing a plot. The first 1 means plot one bar back and the [1] means use the value from one bar back in that plot. This is usually used to join two different line plots together when the color changes else you might get a one bar blank spot.

Xeno, thank you for your reply. This is from the attached Ninja script for the SuperTrend Indicator.

If your intention is to convert SuperTrend to EL, check here:

Due to time constraints, please do not PM me if your question can be resolved or answered on the forum.

Need help?
1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first.
2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses.
3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make.
4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance.
5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers.

Mike, thanks for tip. That is actually where I started. I ran your code but the display was nothing like the NT indicator that supposedly does the same thing. I could not really tell why, hence I needed to convert line-by-line directly from the NT script to see where the discrepancy was. I believe the code difference is minor but the resulting display differences are not.

If you are familiar with Ninja script I would appreciate if you take a quick look at the attached, maybe something will jump out at you.

Thank you in advance.
