In finance, messengers play a crucial role in the execution of orders received by phone clerks. Their swift communication with brokers in the trading pit ensures the timely execution of trades. As intermediaries between clients and brokers, messengers must possess a deep understanding of market dynamics and be equipped with efficient communication skills. Without them, the smooth flow of trading would be greatly hindered. So next time you see a messenger rushing through the trading floor, remember the important role they play in the finance world.
