SMA(int period)[int barsAgo] curious.

[BernWillChris]

Hi,

I'm making an effort to learn as much syntax as possible so that using API's are a lot easier. Unfortunately, the syntax in API's are very advance and I can't find a single text out that is willing to take the challenge.

I praise Ninjatrader for providing excellent resources and examples on how to use the API. I found it the easiest to use. I'm not sure if SMA(int period)[int barsAgo] is C# related or just part of NInjascript. I always considered Ninjascript more of an API for C#. Am I correct?

Not quite: NinjaScript is a framework, built on C#.

Okay!! Is the syntax for SMA Ninjascript specific? And I thought Frameworks and API's are the same. Yikes, it is easy to switch from programming language to another, but each language calling something different can be confusing. I'm assuming that C++ call them libraries, Java call them API's, Python call them Modules, and C# call them Frameworks,

Yes, and no. The syntax for calling/accessing a class depends on how the constructors of the class are programmed, so ultimately, you are talking standard class semantics from C#.

What however, the NT framework does with indicators (but not strategies), is to create methods that directly call the class constructors and return the class object, and also to create a cache to hold the objects, as soon as they are loaded. See all that stuff that NT puts in the indicator, with dire warnings to "not touch"?

So yes, the way of creating instance indicators is NT specific, but it is still just a layer over standard C#, that leverages C#, and takes care of some things for you without you having to think about or code them.

Thanks!

I did looked at the SMA code, but didn't see how they were able to add the [] add the end of the function. I will look at it again later. It would be nice if I can figure that out so that I can use that tool in my arsenal to brighten up my code.

Thanks again.
