The future of stock trading appears to be electronic, as competition is continually growing between the remaining traditional New York Stock Exchange specialist system against the relatively new, all Electronic Communications Networks, or ECNs. ECNs point to their speedy execution of large block trades, while specialist system proponents cite the role of specialists in maintaining orderly markets, especially under extraordinary conditions or for special types of orders.
The ECNs contend that an array of special interests profit at the expense of investors in even the most mundane exchange-directed trades. Machine-based systems, they argue, are much more efficient, because they speed up the execution mechanism and eliminate the need to deal with an intermediary

A stock exchange, securities exchange or (in Europe) bourse is a corporation or mutual organization which provides "trading" facilities for stock brokers and traders, to trade stocks and other securities. Stock exchanges also provide facilities for the issue and redemption of securities as well as other financial instruments and capital events including the payment of income and dividends. The securities traded on a stock exchange include: shares issued by companies, unit trusts and other pooled investment products and bonds. To be able to trade a security on a certain stock exchange, it has to be listed there. Usually there is a central location at least for recordkeeping, but trade is less and less linked to such a physical place, as modern markets are electronic networks, which gives them advantages of speed and cost of transactions. Trade on an exchange is by members only. The initial offering of stocks and bonds to investors is by definition done in the primary market and subsequent trading is done in the secondary market. A stock exchange is often the most important component of a stock market. Supply and demand in stock markets is driven by various factors which, as in all free markets, affect the price of stocks (see stock valuation

[edit] Barometer of the economy
At the stock exchange, share prices rise and fall depending, largely, on market forces. Share prices tend to rise or remain stable when companies and the economy in general show signs of stability and growth. An economic recession, depression, or financial crisis could eventually lead to a stock market crash. Therefore the movement of share prices and in general of the stock indexes can be an indicator of the general trend in the economy
