Question

I’m not quite sure how to ask my question in C# terms, so please bear with the long-winded explanation.

I’m writing a stock trading algorithm. When the algo starts, it checks to see what kind of instrument it is applied to (in this case, either stock or futures), and then depending on the instrument, assigns a value to “double x”.

If its a future instrument, then the assignment is a simple, flat value (in this case, “double x = 5;). However, if its a stock, I’d like “x” to be assigned to a value from another object – lets call the object “Algo2” and the value “y”. So, in my script the assignment is as follows: “double x = Algo2.y” (note: that’s the convention in the editor I’m using). This block of code is run only once when the algorithm begins.

What I’m trying to achieve here is to tell my algorithm to get the latest value of “Algo2.y” whenever “x” is used in a formula such as “EntryValue = Price + x”. However, whats happening is that “x” is permanently assigned the value of “Algo2.y” at the start of the program, and since that block is never run again, remains that constant value throughout.

Can anyone help with the syntax so that instead of assigning a value to “x”, it simply points to get the latest value of “Algo2.y” whevever it’s called?

Thanks!

Answer 1

Write a function for it:

double getAlgo2YValue()
{
    return Algo2.y; // or Algo2.getY(), another function if you can't access it
}

In your main algorithm, now call:

x = getAlgo2YValue();

To update X.
