I called Tradestation, but they said to look them up myself. I looked up most on Tradestation symbol lookup. I also googled many of the symbols I need, but a few I've not found. Here is the list- 1.Prem (S&P/ES)- It used to be $PREM, but it says it's invalid 2.CAC 40- 3.Nikkei index- 4.Hang Seng index- Thanks
