1.Wall Street has changed because of introduction of electronic trading because nowadays people are no more dependent on physical delivery and there are more electronic delivery in nature.
Wall Street has also changed because the number of participants has increased dramatically and there are global participants in the United State market and it is not a domestic market anymore.
