Abstract: A trading system transitions from a first state to a second state and may award a participant, when one or more criteria and/or a status of trading rights are met, with trading priority in the second state to trade on an incoming contra order. The participant may also have an associated order modified as a result of an incoming contra order and/or be caused to automatically trade on an incoming contra order.

Abstract: A trading system transitions from a first state to a second state and may award a participant, when one or more criteria and/or a status of trading rights are met, with an exclusive and/or semi-exclusive right in the second state to trade on an incoming contra order.

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.

Abstract: Systems and methods for trading an item in an electronic trading system are provided. The method preferably includes transitioning the trading system from a first trading state to a second trading state. Once the trading system has transitioned to the second state, the method includes determining whether an existing order qualifies for trading priority and/or exclusivity in the second trading state with respect to an incoming contra order. This determining of trading rights in the second trading state is preferably based on the status of trading priority in the first trading state and also a set of predetermined criteria with respect to an incoming contra order in the second trading state. If the existing order qualifies for trading priority, then the system preferably presents the incoming contra order for trading exclusively or semi-exclusively to the participant associated with the existing order.

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.
