C# Array and storing data

[tinkerz]

As I understand it the dataseries stores a number until the bar closes, that number can change via updates, but the reference is the historical bar.

I was wondering if there is an array in C# that can store incoming data, lets say in a fixed array of 128.

And be able to remove the oldest data and replace with the new data sequentially?

Then once the data is stored in the array you could run frequency algo's, just a thought, be nice though :)

Thanks

tinkerz, the concept you can search for is called a stack (http://dotnetperls.com/stack). Basically it is an array designed to have data pushed into it and popped out, without any extra overhead.

also look up a "queue" data structure
