The rise of electronic and algorithmic trading has irrevocably changed how the financial markets operate. Equity markets have been known to be almost entirely electronic since 2015. Moreover, according to Greenwich Associates, over 90% of equity flows are executed electronically in liquid, developed markets like the U.S. It’s no secret that floor trading has dwindled. Just take a look at the floor of the New York Stock Exchange. When I was a specialist, there were thousands of traders and market makers on the floor of the exchange, but in the past decade or so that number has dropped to only a few hundred.
