MeFi post: The sign language of capitalism.

Corpse - most exchanges are purely electronic these days - it's easier to scale when you're electronic, and more trades means more commissions for the exchange.

The older the exchange, the more likely it is to still use open-outcry; Nymex and Nybot are still partly open-outcry, and the London Metals Exchange is as well. You can even come in and watch the LME ring sessions, once you jump through a few security hoops.
