Hey Git. Actually, it's built right into the Alpari UK platform I was already using. I was just browsing through the different pairs one day and found the indices along with the pairs.
Here's the breakdown that has the DOW 30 and the S&P 500 futures listed. I just turned em on and Voila! Since it's futures trading, I can watch it round the clock along with the pairs. :-)
All the commodities are there too...corn, sugar, soy beans, etc...
