Why Does an Open Outcry Matter?
Open outcry is the original and, some would say, the best method for matching buyers and sellers.

In addition, some believe that open outcry can prevent collusion because literally any trader can enter a market and take advantage of wide spreads; this is often not the case for electronic trading systems whereby a small number of large market makers could keep spreads wider than necessary.
