In the 1929 Wall Street Crash, which U.S. exchange was the main trading venue for the collapsing shares?

The New York Stock Exchange was the main trading venue for the shares involved in the 1929 Wall Street Crash.

The exchange, located on Wall Street in New York City, was already the dominant U.S. securities market. In October 1929, heavy selling produced enormous trading volumes and dramatic price declines. Black Thursday, Black Monday, and Black Tuesday are the dates most often associated with the panic, although the market’s fall continued beyond those sessions.

The crash is often treated as the single cause of the Great Depression, but historians describe a more complicated relationship. Banking failures, shrinking demand, debt, policy decisions, and international economic weaknesses deepened the downturn. Another common mistake is assuming that the exchange itself closed permanently; it continued operating under increasingly strict rules and later reforms.
