Most exchanges went fully electronic more than a decade ago, replacing shouted orders with silent, colorless routing engines. One regional floor kept the shouting — not out of nostalgia, its traders insist, but because it still works better for the contracts they handle.
The floor trades a narrow slice of commodity futures that don't move enough volume to justify a fully automated system. Human traders, standing shoulder to shoulder, can price an unusual order faster than a matching engine tuned for a busier market.
Why noise is sometimes the point
Younger traders on the floor describe an apprenticeship that has nothing to do with screens: reading a colleague's posture, catching a hand signal across a crowded pit, knowing whose word is reliably good before a ticket is even written.
Regulators have twice proposed folding this exchange into a larger electronic system. Both times, the floor's own volume numbers — steady, if modest — were enough to keep the shouting going a while longer.
