Ticker definition: what is a ticker?
A stock ticker is a listing of the ticker symbols of the stocks trading on that particular exchange and carries constantly updated share movements. These report the price of certain securities, which is continuously updated throughout the days trading session. Because of the amount of stock trading on each exchange, the ticker is often limited to the shares moving in large volumes on that day. Its name comes from the ticking sound made by the ticker-tape machines that distributed the early price feeds. Its data can be based on price or on the size of turnover in the stock.
Where have you heard about tickers?
If you have ever seen news footage of a trading floor, you will have seen the large signs used by traders to keep track of stock movements. The modern stock tickers are exactly as they are portrayed in the movies. Big electronic LED screens that display rolling market data in real time. A smaller version of these are often displayed at the bottom of the screen during news coverage on TV. You have these visual stock tickers on a variety of financial news networks. Green tends to be used to indicate a rising price and red tends to be used to indicate a falling price.
History of tickers.
The first ticker tape was invented by Edward Calahan in 1867 - an employee of the American Telegraphy Company. A mere four years later, Thomas Edison improved upon the ticker and went on to patent it. The patent was for a mechanical tickers that printed on paper making increasing the efficiency of the flow of information. As technology evolved, information became more readily available, which led to the ticker as it is seen today.
Ticker meaning: what you need to know about tickers.
Every stock exchange uses stock tickers to keep traders up-to-date on share price movements; each such movement is called a 'tick'.
Stock tickers have come a long way from their roots in the telegraph system. Tickers are now fully electronic, and many on-line investment platforms allow traders to customise their own stock ticker, which can be displayed on their computer screen.
One by-product of the shift to electronic information has been the end of the traditional ticker-tape parade through the city streets for heroes such as American astronauts. These days, either specially manufactured 'ticker-tape' or confetti is used.
