Island Exchange
Island ECN was one of the first electronic communication networks established for the trading equities in the United States. Founded in 1996 by Datek Securities veterans Jeff Citron and Joshua Levine, Island executed its first trades in 1997. History Prior to Island, Citron and Levine worked together at Datek Securities (now TD Ameritrade). Citron's background was in trading and Levine had experience with software development. While at Datek, they worked together to develop a software program called Watcher. Watcher was one of the first programs to provide real-time quote and electronic order capabilities for trading Nasdaq stocks through the Small Order Execution System (SOES). In 1995, Watcher was augmented with a system called "Jump Trades" that let users of Watcher skip the Nasdaq intermediary and trade directly with each other. On February 9, 1996, Levine announced the launch of Island. Unlike the existing Instinet system, which still used human traders to match buy and sell ...

Electronic Communication Network
An electronic communication network (ECN) is a type of computerized forum or network that facilitates the trading of financial products outside traditional stock exchanges. An ECN is generally an electronic system accessed by an electronic trading platform that widely disseminates orders entered by market makers to third parties and permits the orders to be executed against them in whole or in part. The primary products that are traded on ECNs are stocks and currencies. ECNs are generally passive computer-driven networks that internally match limit orders and charge a very small per share transaction fee (often a fraction of a cent per share). The first ECN, Instinet, was created in 1969. ECNs increase competition among trading firms by lowering transaction costs, giving clients full access to their order books, and offering order matching outside traditional exchange hours. ECNs are sometimes also referred to as alternative trading systems or alternative trading networks. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equities
Stocks (also capital stock, or sometimes interchangeably, shares) consist of all the 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 senior claims such as secured and unsecured debt), or 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 shareholders. Stock can be bought and sold privately or on stock exchanges. Transactions of the former are closely overseen by governments and regulatory ...

Small Order Execution System
The Small-Order Execution System (SOES) was a system to facilitate clearing trades of low volume on Nasdaq. It has been phased out and is no longer necessary. History SOES was first introduced in December 1984 for 25 stocks to provide automatic order execution for individual traders with orders less than or equal to 1000 shares. The lack of liquidity after the 1987 market crash led Nasdaq to enforce mandatory use of the SOES by all market makers using the NASDAQ National Market System, providing excellent liquidity for smaller investors and traders. Initially, when SOES was mandatory, it was met with heavy pessimism from Nasdaq member firms because it forced them to execute all SOES trades that met the market maker's advertised price. There were also significant limitations implemented to prevent day traders from exploiting the system and taking advantage of old prices quoted by market makers. SOES operated alongside another electronic system called SelectNet, launched in 1988, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
