Thread: How to create a simple function and access it from indicators

I know how to create functions (methods) in C#; I know how to use Strategy Trader to create functions. Unfortunately, they don't look very much alike and I can't find an explanation within the limited documentation available.

What is the point of class constructors like:
public Average(BaseTechniqueService ctx, int data_stream) :
base(ctx, data_stream) { m_datastream = data_stream; }

I know it is a class constructor, but what are BaseTechniqueService and data_stream for?

To clarify my need a bit. I want to create a function that accepts three double values and returns a double result. It is simple and straight forward in standard C#. How is it done in Strategy Trader?

public double CalcMyNumbers(double x, double y, double z)
{
double calcdResult = x - y / z;
return calcdResult
}

Can anyone explain how to do this?

It is my understanding that the "ctx" statement when used with the overload "data_stream" is for strategies, functions and indicators that utilize multiple timeframes. Therefore, if you have two (or more) time frames then the first "ctx" statement does not require the "data_stream" overload, but all other time frames do require a separate "ctx" statement and they all have to be given the "data_stream" overload for each separate time frame.

Thanks for the clarification. I guess that means a basic function such as I described in my op doesn't actually need the ctx or datastream info.
