New York Stock Exchange, Stock exchange in Lower Manhattan, US

The New York Stock Exchange occupies a light-colored stone building at 11 Wall Street and 18 Broad Street, with a portico of six fluted columns topped by a triangular pediment filled with carved relief figures. Three flags hang from poles between the columns, and a black metal fence runs along the sidewalk. The exchange is the world's largest by market capitalization and lists Intercontinental Exchange under the ticker ICE.

On May 17, 1792, twenty-four brokers signed the Buttonwood Agreement, setting a minimum commission and giving signers preference in sales. The brokers reorganized in 1817 as the New York Stock and Exchange Board and rented space after trading at the Tontine Coffee House. Several sites served until 1865, when the present location was adopted; the 1869 merger with the Open Board of Stock Brokers raised membership and volume.

The exchange is nicknamed "the Big Board", and its Luncheon Club occupied the seventh floor from 1898 until it closed in 2006. The American flag stretched across the Broad Street facade is changed regularly, and passers-by stop to photograph the pediment sculpture and the inscribed name band.

The exchange occupies the building at 11 Wall Street and also fronts 18 Broad Street, where the six-column portico faces the street. The interior is closed to the public; the sidewalk along Broad Street gives the closest view of the pediment sculpture and the flags. Weekday mornings bring the heaviest foot traffic.

The exchange's Stock Exchange Luncheon Club occupied the seventh floor from 1898 until it closed in 2006. Until August 2000, all stock prices on the floor were quoted in fractions of eighths, a system inherited from 17th-century Spanish pieces of eight; decimal quoting was completed by the end of 2001.
