Which 1929 New York exchange had the record trading day that became Black Tuesday?

The New York Stock Exchange had the record trading day that became Black Tuesday in 1929.

On October 29, 1929, approximately 16 million shares changed hands on the NYSE as investors rushed to sell. The exchange was then the central marketplace for U.S. listed shares, so its collapse in confidence had consequences far beyond the trading floor.

The NYSE was founded in 1792 through the Buttonwood Agreement, when stockbrokers organized rules for trading securities in New York. By 1929, the exchange had become an important symbol of American finance and the era’s speculative boom.

The exchange itself did not create every condition behind the crash. Margin buying, uneven economic growth, banking weaknesses, and excessive optimism all mattered. Also, the NYSE remained active after Black Tuesday; the crash was a sustained market decline rather than a permanent closure.
