Last week, CME Group announced that it would close all its New York trading floors at year-end. For the first time since 1872, when the Butter and Cheese Exchange opened its doors, beginning in 2017, New York City will not house a trading facility for futures where humans can interact in person. CME Group commits to maintain its physical trading facility in Chicago for at least some foreseeable time, but, inevitably, the trading pits there will also go silent. Economics clearly support the closing of trading floors. However, it’s sad that in just a few years, when someone accidentally flips channels late at night and stumbles upon the film Trading Places, they will have no idea what that glorious place is where folks screamed, pushed and shouted just to buy and sell orange juice futures.
