How to create a base series?

[atrader]

Hello, I am trying to create an array to hold data such as when sma cross. Can I use something like
MySeries = new Series<double>(this);
If I can, create the array base to replace "this" in the example above. Since the array is not based on each bar, I would prefer not to use the array based on bar, such as BarsArray[1], etc.
Thanks!

Hello atrader,

If you don't need a value for every bar, use a list.

If you need to store multiple values (such as a bar number, and a double price) use a list of arrays.
Something like:

private List<double[2]> myList = new List<double[2]>();
myList.Add(new double[2] { CurrentBar, Close[0] } );

Hello Chelsea,

Thank you so much for your information. One more question, how to make the index like the bar, that is each new added element has the index 0, the previous element has is 1 and so on. I know that I may have to define a fixed number of the elements for the list first and use a for loop to update the index for each element when adding new element. But this involves a lot of calculations. Is there a better way to do it?

Thank you!
