General Functions Library

[pakricard]

Hi:

I'm coding several indicators and strategies in NT and I would like to create a library with the functions that are used here and there, so I do not need to maintain duplicated code.

How Can I create a library with a collection of functions in NT?

Thanks,

Create partial classes in the Indicator and Strategy namespaces. The easiest way is to copy the UserDefinedFunctions.cs file to another name, and place your function code in there.

You can segment your library into separate files, so that you only need to export the functions necessary for each indicator/strategy, if you choose to distribute your code.

Great! Simple and worked!

BTW, i declared the functions as public, is it correct?

public works, but I generally declare them as protected.

It did work to re-use functions in several indicators. but, when trying to use the functions in strategies, I get "The name namefunction does not exist in the current context" when compiling. I guess I should tell the strategy to get functions from my UserDefinedIndicator.cs file... Is there any directive to do so?

There are separate UserDefinedMethods.cs files for strategies and indicators. You will need to do the same for your libraries. After all, look at how the partial classes are being declared. I said as much in my first response: "Create partial classes in the Indicator and Strategy namespaces." (emphasis added).

It is possible to use the indicators library files in a strategy, but you will then have to declare a dummy indicator in the strategy, just so that you can call its functions, as functions out of an object. Altogether too cantankerous for my liking.
