Can someone tell me why floor traders in commodities still exist in America? What is the benefit of them over a machine, and what can they do that a machine can't do. I noticed when NYMEX went electronic for energy side by side, volume exploded mostly from electronic trading. At the very least, every comm market that a floor trader is in, should also have electronic side by side, that way I could get some choice. The NYSE floor is quickly becoming a sleepy place...many specialists have been let go. Do you guys see this trend happening at the NYMEX & CBOT too?
