Stock Market Data Systems
Stock market data systems communicate market data—information about securities and stock trades—from stock exchanges to stockbrokers and stock traders. History The earliest stock exchanges were in France in the 12th century and in Bruges and Italy in the 13th. Presumably data about trades in those times was written down by scribes and traveled by courier. In the early 19th century Reuters sent data by carrier pigeons between Germany and Belgium In London early exchanges were located near coffee houses which may have played a part in trading. Chalk boards In the late 1860s, in New York, young men called "runners" prices between the exchange and broker's offices, and often these prices were posted by hand on large chalk boards in the offices. Updating a chalk board was an entry point for many traders getting into financial markets and as mentioned in the book Reminiscences of a Stock Operator those updating the boards would wear fur sleeves so they would not accidentally ...

Market Data
In finance, market data is price and other related data for a financial instrument reported by a trading venue such as a stock exchange. Market data allows traders and investors to know the latest price and see historical trends for instruments such as equities, fixed-income products, derivatives, and currencies. The market data for a particular instrument would include the identifier of the instrument and where it was traded such as the ticker symbol and exchange code plus the latest bid and ask price and the time of the last trade. It may also include other information such as volume traded, bid, and offer sizes and static data about the financial instrument that may have come from a variety of sources. It is used in conjunction with the related financial reference data that is typically distributed ahead of market data. There are a number of financial data vendors that specialize in collecting, cleaning, collating, and distributing market data and this has become the ...

Stock
Stocks (also capital stock, or sometimes interchangeably, shares) consist of all the Share (finance), shares by which ownership of a corporation or company is divided. A single share of the stock means fractional ownership of the corporation in proportion to the total number of shares. This typically entitles the shareholder (stockholder) to that fraction of the company's earnings, proceeds from liquidation of assets (after discharge of all Seniority (financial), senior claims such as secured and unsecured debt), or Voting interest, voting power, often dividing these up in proportion to the number of like shares each stockholder owns. Not all stock is necessarily equal, as certain classes of stock may be issued, for example, without voting rights, with enhanced voting rights, or with a certain priority to receive profits or liquidation proceeds before or after other classes of Shareholder, shareholders. Stock can be bought and sold over-the-counter (finance), privately or on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quotron
Quotron was a Los Angeles–based company that in 1960 became the first financial data technology company to deliver stock market quotes to an electronic screen rather than on a printed ticker tape. The Quotron offered brokers and money managers up-to-the-minute prices and other information about securities. The Quotron was developed by Scantlin Electronics, owned by entrepreneur John Scantlin. Scantlin had earlier developed a quotation device that used magnetic tape instead of ticker tape. Quotron's first major competitor was Telerate, which was founded by Neil Hirsch in 1969 and later bought by Dow Jones in 1990. Citicorp bought Quotron in 1986. At the time Quotron was renting 100,000 terminals which equated to 60 percent of the 1986 market for financial data. Following the Citicorp acquisition, Quotron's largest client, brokerage house Merrill Lynch, decided not to renew their contract with Quotron. Merrill Lynch instead invested in a competing startup named Bloomberg. Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Switchboard Operator
In the early days of telephony, companies used manual telephone switchboards, and switchboard operators connected calls by inserting a pair of phone plugs into the appropriate jacks. They were gradually phased out and replaced by automated systems, first those allowing direct dialing within a local area, then for long-distance and international direct dialing. Description A typical manual telephone switchboard has a vertical panel containing an array of jacks with a desk in front. The desk has a row of switches and two rows of plugs attached to cables that retract into the desk when not in use. Each pair of plugs was part of a cord circuit with a switch associated that let the operator participate in the call or ring the circuit for an incoming call. Each jack had a light above it that lit when the customer's telephone receiver was lifted (the earliest systems required the customer to hand-crank a magneto to alert the central office and, later, to "ring off" the completed ca ...

Chicago Board Of Trade
The Chicago Board of Trade (CBOT), is an American futures exchange, futures and options exchange that was founded in 1848. On July 12, 2007, the CBOT merged with the Chicago Mercantile Exchange (CME) to form CME Group. CBOT and three other exchanges (CME, NYMEX, and COMEX) now operate as designated contract markets (DCM) of the CME Group. History The Chicago Board of Trade (CBOT), established on April 3, 1848, is one of the world's oldest futures and options exchanges. It was created as a centralized venue where buyers and sellers could meet to negotiate and formalize forward contracts. The idea originated from a conversation between Thomas Richmond and W. L. Whiting, who discussed the potential benefits of forming a board of trade. Their exchange led to a March 13 meeting of merchants and businessmen who supported the initiative, resulting in a resolution to create the institution and draft a constitution. A committee was then formed to develop bylaws, which were officially ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Mercantile Exchange
The New York Mercantile Exchange (NYMEX) is a commodity futures exchange owned and operated by CME Group of Chicago.

Electronic Display
An electronic visual display is a display device that can display images, video, or text that is transmitted electronically. Electronic visual displays include television sets, computer monitors, and digital signage. They are ubiquitous in mobile computing applications like tablet computers, smartphones, and information appliances. Many electronic visual displays are informally referred to as touch screens. Starting in the early 2000s, flat-panel displays began to dominate the industry, as cathode-ray tubes (CRT) were phased out, especially for computer applications. Starting in the mid 2010s, curved display panels began to be used in televisions, computer monitors, and smartphones. Types There are various technologies used for electronic visual displays: * Liquid crystal display (LCD) including LED-backlit LCD * LED display **OLED display ** AMOLED display * Plasma display * Quantum dot display * Electroluminescent display An overhead projector can be considered a type o ...

Brokerage
A broker is a person or entity that arranges transactions between a buyer and a seller. This may be done for a commission when the deal is executed. A broker who also acts as a seller or as a buyer becomes a principal party to the deal. Neither role should be confused with that of an agent—one who acts on behalf of a principal party in a deal. Definition A broker is an independent party whose services are used extensively in some industries. A broker's prime responsibility is to bring sellers and buyers together and thus a broker is the third-person facilitator between a buyer and a seller. An example would be a real estate broker who facilitates the sale of a property. Brokers can furnish market research and market data. Brokers may represent either the seller or the buyer but generally not both at the same time. Brokers are expected to have the tools and resources to reach the largest possible base of buyers and sellers. They then screen these potential buyers or selle ...

Rear Projection
Rear projection (background projection, process photography, etc.) is one of many in-camera effects cinematic techniques in film production for combining foreground performances with pre-filmed backgrounds. It was widely used for many years in driving scenes, or to show other forms of "distant" background motion. Technique Actors stand in front of a screen while a projector positioned behind the screen casts a reversed image of the background. This requires a large space, as the projector needs to be placed some distance from the back of the screen. Frequently the background image may initially appear faint and washed out compared to the foreground. The image that is projected can be still or moving, but is always called the ''plate.'' One might hear the command "Roll plate" to instruct stage crew to begin projecting. These so-called ''process shots'' were widely used to film actors as if they were inside a moving vehicle, who in reality are in a vehicle mock-up on a sound ...

Stock Market Crash
A stock market crash is a sudden dramatic decline of stock prices across a major cross-section of a stock market, resulting in a significant loss of paper wealth. Crashes are driven by panic selling and underlying economic factors. They often follow speculation and economic bubbles. A stock market crash is a social phenomenon where external economic events combine with crowd psychology in a positive feedback loop where selling by some market participants drives more market participants to sell. Generally speaking, crashes usually occur under the following conditions: a prolonged period of rising stock prices (a bull market) and excessive economic optimism, a market where price–earnings ratios exceed long-term averages, and extensive use of margin debt and leverage by market participants. Other aspects such as wars, large corporate hacks, changes in federal laws and regulations, and natural disasters within economically productive areas may also influence a significant decline i ...
