Getting Math function to work in NT8

[elcowen]

How do I reference the Math Class??

VolumeX = Math.Statistics.InverseNormalDistribution(Volume[0], Mean, Std); ??

Cant get to work.

Thank you!

Hello elcowen,

Welcome to the support forums.

Was the code you copied from something you had seen or used before? In C# the math library does not have a function named InverseNormalDistribution nor a Statistics namespace. This is also not something which comes default in NinjaScript.

I look forward to being of further assistance.

I followed the link in NinjaTrader Docs for Math.Class (https://ninjatrader.com/support/help...erence_wip.htm)

Here's the linked site which does have the math I need.

https://docs.microsoft.com/en-us/dotnet/api/system.math?redirectedfrom=MSDN&view=netframework-4.8#methods

How do I call these math functions in NT?

Thanks Jesse!

Hello elcowen,

The page you linked to is just the general help guide, you will need to right click on the link in the help guide and select copy link. Otherwise if the page has a link at the bottom that says permalink you can copy that.

Are you asking how to use the code shown on MSDN in NinjaScript? If so that sample has methods and you could copy/paste them into your file if you wanted to use those specifically. The C# math functions can be used by using word Math or Math.Min() as an example.

I look forward to being of further assistance.

Yes how do I use the MSDN code in NinjaScript? Do I have to import the module?? I just need access to statistics and other quantitative functions. If there's an easier way thats fine too.

Thanks so much!

Hello elcowen,

NinjaScript is just C# so you would use it just like you would in C# or in those examples. You need to make sure you have the System namespace in the using statements at the top of the file, aside from that nothing else would be needed. A default indicator should be able to use the Math class and its methods.

protected override void OnBarUpdate()
{
    Print(Math.Min(12,10));
}

I am not aware of the statistics methods you are referring to but if that is something from a C# library you can likely use it.

I look forward to being of further assistance.

Ok, so there's no way to utilize the math I referenced? Is there add-ons or anything where I can get access to quantitative methods? Thanks

Hello elcowen,

Ok, so there's no way to utilize the math I referenced?

Where did you copy that code from? Or was that just an example of what you want to make?



Please let me know if I may be of additional assistance.

That Microsoft link has the math I need (the InvNormalDist) but how to I get access to that function in Ninjatrader? Thx!

Hello elcowen,

That Microsoft link has the math I need (the InvNormalDist)

What link specifically? The links you provided did not link to anything specific and don't contain either of the items you are asking about. Please check the link you copy and make sure it goes to what you are trying to show.

If you can provide the direct link to what you originally asked about or what you are asking about in post 9 I could try to assist further.



Please let me know if I may be of additional assistance.

My bad. Sorry

I followed the link in NinjaTrader Docs for Math.Class (https://ninjatrader.com/support/help...erence_wip.htm)

Here's the linked site which does have the math I need.

I just need access to any math functions (more than the basic ones NT provides). Doesnt matter where it comes from. I need to do statistical modeling somehow. Thanks!

Hello elcowen,

You provided the same link again which just goes to the help guide in general, please check the links you copy before replying to the post.

If you want a link to something in the help guide you cannot use the address bar, right click on the link in the sidebar and copy its link or use the permalink at the bottom of the page.


The second link is to the Math in C#, what specifically on that page are you trying to use?

I just need access to any math functions (more than the basic ones NT provides).

Ok what math do you need and where does it come from? I would need a link to what you need help using so I can try to assist here. The links so far have not helped to explain the question further.

Doesnt matter where it comes from. I need to do statistical modeling somehow.

Again where does it come from? If you need something that is not available in NinjaScript or in C# you will have to likely create that or use a library/something external. If you have something in mind I may be able to help if you can provide a link directly to it.



Please let me know if I may be of additional assistance.
