Yes, but to do real HFT you will need to colocate at each exchange.
Otherwise your competitors have a head start on you.

Most traded index futures are longer than just that day closing, usually
months to a year in advance.
They are influenced mostly by traders perception on economic futures, and
the current stocks valuation is a poor proxy for it.
There is more chance in reading the news feeds and speculating its impact
on perception than stocks.
