The NYSE grew very quickly. A constitution was adopted in 1817. A few of the rules of this constitution was that there will be a “call the market,” where the president reads all stocks due to be traded for the day and each broker trades their stocks in turn, much different then the mass confusion today inthe market place. Another rule used was that there would be two trading sessions during the day on inthe morning and one in the afternoon. It was very structured and calm. In 1832 the stock market was changed forever. They passed a rule in which people could not trade outdoors.They must trade indoors. In 1884 the telegraph was invented. This invention revolutionized trading in the NYSE much like the Internet has revolutionized trading now. Wealthy businessmen could now keep in touch withtheir broker much more easily. Also brokers could find new clients out of the New York area.
