Need for normsdist() function

[Steve R]

As i understand it, in C# this function does not come readily available for use in NT.

I found this thread here in a search.

My quick question is, I want to just use normsdist() within an indicator, not export anything to Excel as the were doing in the linked thread.

Is the first few posts there all that is involved?

My novice assumption is that once i 'import', what i will simply call "the ability to know what normsdist() IS as far as the indicator is concerned", I can then just use it in my usual coding, with variables etc etc as per normal.

Sounds too easy? What am i missing?

Hello Steve,

Thank you for your post.

I have not tested this enough to know if you can call normsdist() using the instructions outlined in your referenced thread. I would suggest testing this on your end or asking upon the thread you referenced.

Not too likely as i am way under-learned.

In fact the more i read that other thread i do not think i should have even referenced it.

I think a better question is..... how can i use the normsdist() function?

Are there any library's or anything i could import to the "Using Declarations" region that would make the job easy enough?

I think my original idea is just plain wrong thinking.

Hello Steve R,

Thank you for your response.

There unfortunately would not be a .dll we could reference for this. You can add you own method to calculate the normal distribution as seen at the following link and then add this to your UserDefinedMethods file and now you can call it for any indicator: http://www.daniweb.com/software-deve...-formula-in-c-

Hi Patrick. Thanks for that.

normsdist harder to find and calc!

but if i can figure that out we are good to go.

AH i think i have found the cumulative part here in this link for future reference for anyone looking.

It's a two-part idea and i have not done it yet myself, plus i want to look and see if "ERF" is part of the Math library already present, but my guess is it is not.

And of course no, C# does not have erf().

Here's another link for erf function required to perform nomsdist(), but it is also found in the previous link. At first glance they look the same to me.
