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: A method includes receiving electric field data regarding an electric field that is detected in an underwater environment by a plurality of electrodes mounted on a first structure, and receiving sensor data from at least one sensor mounted on the first structure. The sensor data relates to a sensed location of a second structure. The method includes determining location data including information regarding a location of the second structure relative to the first structure in the underwater environment based on the sensor data, and determining one or more characteristics of the second structure based on the electric field data and the location data.

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: 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.
