Abstract: A computer system is provided that includes a paired list of data transaction requests on which a matching process is performed. There are multiple different types of data transaction requests that are stored in the paired list including data transaction requests with midpoint attributes and data transaction requests with discretion attributes. The computer system may determine how the multiple different types of data transaction requests may be match against each other. Two matching processes can be used to determine if a match exists between the first and second sides of the paired list. Matches that are determined at private values are not disseminated to third-parties via public market data feeds.

Abstract: A user interface for use with an electronic trading system includes a display that shows a bid price axis and an ask price axis, as well as corresponding sizes, and a visual indicator of the inside market. When the inside market changes in response to changing market conditions, the display of the inside market clearly shows a spatial movement of the inside market as well as the representative price(s) associated therewith, thereby rendering the two price axis dynamic axis. The user interface is easy to use, intuitive as well as customizable, and contains features that facilitate efficient electronic trading and shows trading activity pertaining to the user as well as the market in general.

Abstract: Systems and methods for providing trading exclusivity/priority in response to quantity of items traded in electronic trading systems is provided. The method preferably includes receiving an incoming order for the item and determining whether the incoming order matches a current order for the item and satisfies a minimum volume requirement. When the incoming order matches a current order for the item and satisfies a minimum volume requirement, the method includes transacting a trade between the incoming order and the current order and providing a predetermined time period of exclusive trading between a participant associated with the incoming order and a participant associated with the current order.

Abstract: The invention relates to systems and methods that provide a user interface for use with an electronic trading system. The interface notifies the user that the price at which he or she may have attempted to trade has changed and presents the user with the opportunity to submit, modify or cancel the trade command. The user may configure the trading system to enable such a notification based on the time span for the price change, the number of increments of the price change, a combination thereof or any other appropriate consideration for protecting against the occurrence of erroneous price entries. Subsequent trade commands, such as those entered by third parties, may be used to validate prices and execute trades at these prices.

Abstract: Systems and methods of trading items on an electronic trading system according to the invention are provided. The embodiments of the invention are based at least in part on a new order type. The new order type is a modification of a conventional good-until-bettered order type. A good-until-bettered bid/offer is received along with instructions that specify a good-until-bettered increment value and/or duration. The good-until-bettered order is maintained in the electronic trading system until a bid/offer that is better by the specified plurality of standard trading increments is received by the electronic trading system and/or remains in the system for the good-until-bettered duration.

Abstract: Systems and methods of trading items on an electronic trading system according to the invention are provided. The embodiments of the invention are based at least in part on a new order type. The new order type is an only at best order type, whereby trades are preferably only executed at the best price the item is being bought or sold.

Abstract: Systems and methods for maintaining the viability of a market order type in fluctuating markets are provided. These systems and methods preferably provide the user with the ability to enter an order as a “conditional” market order. Such an order will preferably only be implemented as a market order under certain specific circumstances—e.g., the market has met a predetermined stability threshold for a preferably predetermined amount of time.

Abstract: Systems and methods for configurable trading interfaces that allow a trader to quickly and easily submit trading commands to a trading system are provided. Using these systems and methods, a trader can using various trading interfaces to initiate trading commands, configure various display features and default command settings, and control a level of command entry verification that is provided to protect against inadvertent entry of incorrect trading commands.

Abstract: The invention relates to systems and methods that provide a user interface for use with an electronic trading system. The interface displays a bid price axis and an ask price axis, as well as corresponding sizes, and an indication of the inside market. When the inside market changes in response to changing market conditions, the indication of the inside market changes locations before being restored to its original location by shifting the bid and ask prices in a direction parallel to the bid or ask price axis. The user may enter trade commands at different price levels using an input device. In order to help prevent such trade commands from being entered at erroneous price levels, the system locks a pointer associated with the input device to a price the user points to during the shifting process, unless the pointer is moved away from that price.
