ON-SCREEN PRICE LOCK FOR ELECTRONIC TRADING

摘要

A system and method of providing an on screen window having a price held for further transactions on an interface for traders of financial instruments. The interface contains a display of products for trading and respective prices for bids and offers. Selection of a particular product results in the display of the price of the product at the instant time the product is selected. The price is held until a confirming key or mouse stroke is received to initiate a trading action such as placing a new order, killing an existing order or hitting or lifting an order. The trading action is allowed only if the displayed locked price matches the current price thus preventing actions when the underlying price has changed in between the selection and initiation of the trading action.
