Abstract: Systems and methods for real-time interactive wagering on event outcomes are presented. Clients are first qualified and given wagering limits before being allowed to interactively wager on event outcomes. Event outcomes may be based on, for example, financial markets and indices, sporting and entertainment events, casino performances, and natural phenomena such as weather and earthquakes. Events on which wagers can be placed include both those with known and unknown outcome probabilities, and wagers can be a fixed-odds type or a spread-bet type. Wager transactions, including acceptances and confirmations, are executed in real time. Clients can customize displays of events on which they are authorized to wager. Real-time client credit management, automatic dealer hedging, automatic price-spread adjustments, and automatic client and dealer defined wagering limits are also provided.

Abstract: A bid/offer spread market is presented that allows a trader to increase liquidity in traded items. A bid/offer spread market maker may make a bid/offer spread market. This bid/offer spread market may be made available to any market participant. In response to the spread market, an aggressor may respond to a bid or an offer with a hit or a take, respectively. In response to the hit or the take, the aggressor or bid/offer spread market maker, respectively, may create a separate underlying market using the selected (bid or offer) spread within a specified amount of time. The other party, a bid/offer spread trader, may trade on the quoted price within a specified amount of time, at which point a trade has occurred.

Abstract: Systems and methods for a trading interface with advanced features are provided. Using these systems and methods, a user may create orders, manipulate orders, cancel orders, configure alternative keyboard settings, and/or obtain additional information on transactions. When a user clicks on a bid and/or offer, a dialog box may pop-up, thereby providing the user with multiple options. To enable customization of the keyboard settings to a user's preference, a keyboard settings feature is provided. Users may also be provided with additional information relating to the user's wish to transact.

Abstract: Systems and methods for instantly quoting a two-sided market. Using these systems and methods, a trader can use various trading interfaces to initiate two-sided market orders based on a value submitted and a pre-set spread amount as configured by the trader.

Abstract: Electronic trading systems and methods which facilitate principal/broker trading are provided. In a first aspect of the invention, a database relating to trading participants in the trading system is designed to indicate which traders utilize a principal/broker relationship and what, if any, limitations are placed on the activity of the broker, trading commands submitted by the broker, and counterparties in a transaction with the broker. In another aspect of the invention, trading commands and executed trades involving principals/brokers may be presented to other traders using special designations. The ability to enter certain trading commands by, and in response to, brokers may be limited. In a further aspect of the invention, anonymous trading features may prevent traders from knowing whether another trader is a broker or principal, may restrict traders from being able to block trading with brokers, and may permit brokers to configure anonymous trading parameters.

Abstract: Embodiments include opening a gaming account of a user. Embodiments include establishing an amount of consideration in the gaming account of the user. Embodiments include, after opening the gaming account and establishing the amount of consideration, authorizing the user to access the gaming account from a computing device by verifying credentials of the user received from the computing device. Embodiments include receiving a first request from the user to enter into a game. Embodiments include receiving a second request from another user to enter into an opposite side of the game. Embodiments include matching, by the computer system, the first request and the second request. Embodiments include forming one obligation with a gaming operator to pay the user for winning the game with the user and forming one other obligation with the gaming operator to pay the second user for winning the game with the other user.

Abstract: Systems and methods are provided to control gaming in electronic trading markets. These systems and methods alleviate the problem of a seller or buyer trying to act on a trader's original bid or offer only to trade at an unfavorable level after the trader changes the bid or offer. A pricing method suspends trading for a period of time if a price difference between two bids or offers by the same trader is too great. A timing method prevents a trader from canceling or replacing a bid or offer for a period of time. These methods provide a more fair and efficient way of executing electronic trades.

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.
