Good day Everyone,
Please, is there a way to index a RollinWindow? For lists, it's, say, Dlist[ : ], if ‘Dlist’ is a list. Thus, for six trading day's before now, I expect something like Roll[:6], where ‘Roll’ is a RollingWindow object. However, I'm finding it difficult, as I can only access Roll[0], Roll[1], etc.
I have attached a backtest for anyone who wants to render some help.

Hi Micheal
The abstract data structure of the Rolling Window is queue (but using first-in-last-out). Thus, accessing all data at once like a hash table is not possible as they need to be called one-by-one under this structure. However, it is possible to create a custom panda series/dataframe to achieve the same goal:
