I use Thinkorswim to check on the E-Mini S&P 500 futures, 'ES20', but I also want to see the FTSE 100, CAC 40, AEX, Hang Seng, etc. But when I enter those names to the search field I get no results, or multiple mixed results. How can I find the world indices equivalent to the S&P 500 futures and be sure I am looking at the right symbol?

Given that there is no symbol standard anywhere for futures contracts, you'll just have to find the resources on whatever data platform you use.
