Trading floors is an OTC product that only professionals who specialize in that kind of thing can do. For retailers, you have to enter a multi-leg floor trade that, for regulatory purposes, also has to include a hedge of walls and some other junk otherwise your margin requirements would be insane.
How is the derivative markets for rugs these days? Outside of the SPX pit, is anything traded in the pit that’s not a cross?
It's neighbor VIX and a couple of things still trade the financial floor of the CBOT - the BOX floor, although I have no sense if any BOX floor volume has actually developed. I'm not 100% sure those remaining products traded the CBOT financials. Parts of the AMEX and the pseudo NYSE floor. New listings definitely have paper and open outcry on the NYSE then, to your point, much of it goes electronic. Not sure about the KCBOT - again it's been a while.
