I'm trying to create indexes based on stocks (Non-US) to get an idea of how certain sectors are performing I.E the FTSE100 that doesn't have sector ETFs. Although this sounds simple enough I haven't actually found anything. I have found on stockcharts this can be made by uploading a spreadsheet, however there must be a website out there that will automatically update this for you. (Happy to pay for a subscription if required.)
https://www.folioinvesting.com/folioinvesting/brokerage-features/folios/ (not sure if this works with non-US stocks)

I guess this explains why you haven’t found anything. Just not much interest and I believe they didn’t have enough people using that product, so it became just a distraction to them.
If you actually want to invest in one of the indexes there are sites that let you build your own. Again, not sure if they support non-US stocks, but I know someone who used (and likes) Motif Investing.
