Limit Order Information System - LOIS

An electronic system used by specialists in the stock market. A limit order information system lists price and size quotes for exchange-listed securities. The data produced by this system is used by subscribers and specialists to locate the most opportunistic market for making a trade because the service distributes information about where a security is traded, order quantities, and bid and offer prices.

This system is used to locate the best securities prices available and produces information about securities traded on participating exchanges like the Nasdaq and NYSE. A limit order is an order to buy or sell a stock at a specific price, and includes information such as order quantities, bid price, offer and the exchange on which the security is listed. Limit orders help protect buyers or sellers of a stock from selling at a price that is higher or lower than desired.
