New York Stock Exchange In 1817 the stockbrokers of New York operating under the Buttonwood Agreement instituted new reforms and reorganized. After sending a delegation to Philadelphia to observe the organization of their board of brokers, restrictions on manipulative trading were adopted as well as formal organs of governance.[13] After re-forming as the New York Stock and Exchange Board the broker organization began renting out space exclusively for securities trading, which previously had been taking place at the Tontine Coffee House. Several locations were used between 1817 and 1865, when the present location was adopted.[13]
