Note 9 — Chapter XXI

A stock operator's one reliable source of information is his ticker and tape. For the benefit of those of my readers who are unacquainted with the paraphernalia by which stock-markets and financial operations are conducted, I would say that the ticker is a small printing machine through which passes an endless paper tape. The machine is run by telegraph wires, and it prints upon the tape letters and figures which are abbreviations of the names and prices of all the stocks and commodities dealt in on the stock-exchanges and boards of trade throughout the world. The instant anything of moment happens anywhere, it is reflected by a rise or fall in the price of securities or commodities such as wheat, corn, pork, cotton, etc., that are dealt in in the different stock-exchanges or boards of trade. As soon as a share of stock or bushel of wheat is sold by one operator to another on the floors of the different exchanges, its price is within a second printed on the tapes in the different offices. Therefore what the ticker "ticks" out onto the tape is instantly read by operators throughout the world, and as "the tape never lies," operators turn to it for their real information. When the ticker begins to increase its clatter and the tape to travel fast, an operator will tell you its activity means something unusual is happening. The ticker begins to talk at ten o'clock each week-day morning and finishes at 3 p.m., with the exception of Saturday, when the hour is 12 noon. These are the hours that the stock-exchanges are in session.
