I haven't used MedVed QT in a long time, but to display indices across the top, I think you just right click in the quote row, choose "edit indices", check the ones you want to see, click "OK" and you should be good to go.
Oh, see you were asking about in IB. Don't know how you do it in IB, or if you have to specially subscribe to get the index quotes. Call and ask: 1-877-442-2757. I'd like to know, too, so let me know what you find out. Tnx.
