Questions about Indices

Hello guys,

I am testing indices and hopefully, I get all my answers so that I can start using them. These are open questions I have. I am using coinbase pro.

  1. Not all tokens are available in all regions. For example, today daily indices say to take a trade on RGT which is not available in NY. so, what do I do in this case?
  2. I thought indices change around 2:30 pm EST but today when I checked at 9:30 AM EST, they were already updated.
  3. Where do I see past daily ROI of the daily index on coinbase pro? I want to see the pattern of ROI, not just cumulative ROI as of now

Please suggest answers.
