low volume 7/30 ?

I don't follow the index futures, but what was the volume like today?
In the energy markets, it was like a holiday..
Didn't see nothing on the holiday schedule or articles why it would be..

I'm assuming it's the Olympics .. Today and last Thursday was low, but last Friday was average..

Anyone can compare?

Thanks

 

Fed meeting, ECB meeting, jobs number...all this week. Market is always dead ahead of these.
