Period

Canada

Stock and commodity traders depended on rapid and reliable price information in order to make buy and sell decisions. Canadian Pacific Telegraphs employed this ticker to provide market price information to subscribers to its quotation service up to the mid-1960s.

Function

To provide a tape printout of stock quotations.

Technical

The "Black Box" ticker was introduced around 1930 as a faster and more reliable replacement for the iconic self-winding ticker, which had proven incapable of matching the data flow from the 1929 crash of the New York Stock Exchange. Like its predecessor the Black Box was an electromechanical device that printed characters on a paper tape, but it did so at almost twice the speed, or around 500 characters per minute. Mechanical tickers remained in service until the mid-1960s, when they were replaced by electronic displays.
