Hi Pfchang,
What are you trying to do with the entire list? Rolling Window inherits from IReadOnlyWindow interface, therefore you could use methods listed there. If you are trying to simple calculations like finding the average of the entire Rolling Window, please see my attached backtest. You might find some more information here.
Please let us know if you have further questions!

Hi Link thank you. What I am trying to achieve is that whenever new data comes in, I would like to make use of the updated RollingWindow object to re-do some computation that involves re-sorting the whole array.
Actually taking a step back, do you think it would be more appropriate to write an indicator class for this computation?

Hi Pfchang,Â
Instead of looping over the RollingWindow object, you can also use `list()` method over the RollingWindow object to retrieve the data you need. Please see my attached backtest for implementation details. Please let me know if you have any other questions, or would like to share more information on your strategy so that we could address your issue in detail.
