Ticker Tape Delay Meter

by the New York Quotation Company

Even with the creation of new laws and programs designed to improve the country's infrastructure and prevent fraud, the events of Black Tuesday still had a dramatic effect on investor psychology. Black Tuesday refers to the stock market crash of October 29, 1929, when frightened stock holders sold nearly 16 million shares (four times normal) on the New York Stock Exchange. The trading volume got so high that it delayed the ticker tape by more than an hour and a half, creating even more anxiety and confusion.

The panic caused by these information delays led to a faster tickertape machine that could handle heavy trading days, but the changeover to new stock tickers was slow and took nearly five years. During this transition period from 1929 to 1934, the New York Quotation Company (owned by the NYSE) came out with a nifty little device, called the Tape Delay Meter. It had a 0-to-60-minutes gauge meant to assure and/or alert the exchange's members on the timeliness of the quotes they were reading off the stock ticker.
