Is there a way to reference positions by index number other than enumerating all positions and tagging, as in:

Even with that, I would have to create a loop to select a specific position....

Sure there is. Firstly, instead of foreach you could use for loop. But even this is unnecessary as each Position is tagged. You just have to call IndexOf of a Position object:

Thank you. The IndexOf property sounds like what I was looking for. I can't find any documentation on ways to use it, although I found a couple of code samples using it with apparent lists. Is this a generic property that can be applied to all lists in WL? Is Positions is a special type of list and that's why it supports this property?

I see now how I can get an Int reference for a specific Position. How can I go the other way and reference positions, e.g. to get the average Net Profit or number of bars held for the last 3 positions?

I think I figured it out. Thanks for setting me in the right direction.

I believe

will always hold true for a numerable C# collection such as Positions, so you don't need the .IndexOf property call. Calling that property unnecessarily will only slow you down. The .IndexOf property is available to all numerable C# collection types. Check the Microsoft .NET framework docs concerning C# collections.

Now you can change/redefine the numeration order of a C# collection such as Positions, say through an inverse sort, but WL 6.X.X isn't doing that with the Positions object.

Thanks! C# coding is not my forte. Appreciate the lesson.
