Abstract: According to one embodiment, a method of managing trading is provided. In a market for a particular type of instrument, buy orders and sell orders are received from a plurality of traders. Each buy order has an associated bid price and each sell order has an associated offer price. A determination is made of whether the particular trading order is an outlying trading order by determining whether the particular trading order differs from at least one comparison price by more than a threshold value. If it is determined that the particular trading is an outlying trading order, a restrictive action is taken regarding the outlying trading order. For example, if a trader subsequently submits another trading order that would trade with the outlying trading order, an alert message may be sent to the trader and the subsequent trading order may be prevented from trading with the outlying trading order at least temporarily.

Abstract: The invention is systems and methods for transferring items with restricted transferability. Initially, the systems and methods wait for a first consumer to make a request to transfer an item after having purchased the item from a provider. The systems and methods then send a request to transfer the item to the provider. This request may indicate inducements to the provider to authorize the transfer. If the transfer is authorized, the systems and methods then present information regarding the item to other consumers. This information may be presented as part of a bidding interface or as part of an advertising interface. Once the second consumer submits a winning bid for the item when the information is presented in a bidding interface, or an acceptable offer when the information is presented in an advertising interface, the transfer of the item can then be completed with or without the assistance of an intermediary.

Abstract: Systems and methods for providing traders with an opportunity to trade on the VWAP price are provided. After a trader enters a VWAP auction session, the trader has a predetermined about of time (i.e., the length of the VWAP auction period) to place bids and/or offers on an item. When the VWAP auction period ends, the electronic trading application matches the VWAP orders. The VWAP orders that are not matched are cancelled. The electronic trading application collects trading information (e.g., price, size, etc.) corresponding to the received orders. The collected information is processed to determine the VWAP price. The VWAP price is presented to the trader and the matched VWAP orders are filled based on the determined VWAP price.

Abstract: Systems and methods for providing trading using an eVWAP price in an illiquid market are provided. In an illiquid market there may be little or no actual trades. During a trading period, the eVWAP price is therefore determined from not only trades, but also unmatched bids and offers. The eVWAP price is determined when new information becomes available or at a specified time interval. The final eVWAP price is determined when the sampling period ends. Once the final eVWAP price is determined, the value of the final eVWAP price is published for use as a price to settle a contract.

Abstract: According to one embodiment, a method of managing trading is provided. In a market for a particular type of instrument, electronic data including buy orders and sell orders are received from a plurality of traders. Each buy order has an associated bid price and each sell order has an associated offer price. A determination is made of whether the particular trading order is an outlying trading order by electronically determining whether the particular trading order differs from at least one comparison price by more than a threshold value. If it is determined that the particular trading is an outlying trading order, a restrictive action is taken regarding one or more trading orders. For example, if a trader subsequently submits another trading order that would trade with the outlying trading order, an electronic alert message may be sent to the trader and the subsequent trading order may be prevented from trading with the outlying trading order at least temporarily.
