Enabling Rebalancing and Use of Optimizers for Custom Data

[UjjawalKRoy-SW]

What problem does the requested feature solve?
I am trying to use rebalancing and optimizers along with my custom data, but I am unable to get it to work as intended as the tool scrapes data from yahoo finance website directly any time I pass rebalancing or optimizer args. It would be great to get these outputs for custom data as well.

A possible solution
Implementing a flag which can be set to true/false in the Engine so that the rebalancing and optimization calculations can be carried out on custom data as well.
