NYSE American, formerly known as the American Stock Exchange (AMEX), and more recently as NYSE MKT, is an American stock exchange situated in New York City. AMEX was previously a mutual organization, owned by its members. Until 1953, it was known as the New York Curb Exchange. NYSE Euronext acquired AMEX on October 1, 2008, with AMEX integrated with the Alternext European small-cap exchange and renamed the NYSE Alternext U.S. In March 2009, NYSE Alternext U.S. was changed to NYSE Amex Equities. On May 10, 2012, NYSE Amex Equities changed its name to NYSE MKT LLC. Following the SEC approval of competing stock exchange IEX in 2016, NYSE MKT rebranded as NYSE American and introduced a 350-microsecond delay in trading, referred to as a "speed bump", which is also present on the IEX.

Orders for the purchase and sale of securities were shouted down from the windows of nearby brokerages, with the execution of the sale then shouted back up to the brokerage. Organizing and 'Curb list' As of 1907, E. S. Mendels gave the brokers rules "by right of seniority", but the curb brokers intentionally avoided organizing. According to the Times, this came from a general belief that if a curb exchange was organized, the exchange authorities would force members to sell their other exchange memberships. However, in 1908 the New York Curb Market Agency was established, which developed appropriate trading rules for curbstone brokers, organized by Mendels. The informal Curb Association formed in 1910 to weed out undesirables. The curb exchange was for years at odds with the New York Stock Exchange (NYSE), or "Big Board", operating several buildings away. Explained the New York Times in 1910, the Big Board looked at the
