During trading hours lots of people use it. But don't think you'll get people who talk trading. They only talk about politics and pornos.
I used to but found I traded better when I didn't have all those losers clouding my judgment. I tried filtering with the ignore feature but what's the point when everyone is on ignore?
In the past there have been some good traders in the index room making calls and having fun. Maybe it will happen again sometime...
Last time I was in the Futures room, Osorico was there, knocking out winning trades left and right, and he's a gracious gentleman with lots of experience. There's a couple of other guys in there that are reaping the rewards of their hard work, and some are really good at explaining what they see and how they see it. I just missed too many good trades paying too much attention to the room instead of my job. I love my job!
