Abstract: Systems and methods for trading commodity, an item or instrument are provided. The market prices and trading may be monitored to detect a spike in the market price or artificially high market price. Excess profits resulting from the sale at an artificially high market price may be distributed to market participants based upon the participant's trading record in the market or upon some other suitable method.

Abstract: Systems and methods for electronic trading that provide incentives to users of a trading system. The systems and methods may monitor a trading activity of the user and determine that the orders submitted by the user over a period of time exceed a first pre-determined threshold. Systems and methods also determine that a spread of the plurality of orders exceeds a second pre-determined threshold. Based on these determinations, the user is designated as qualifying for a special status, which entitles the user to incentives in trading. Systems and methods apply the incentives to an order submitted by the user. One such incentive provides the user with a priority in a trading queue, where orders submitted by the user are executed in advance of other orders in the trading queue.

Abstract: Systems and methods for linking orders in electronic trading systems are provided. These systems and methods enable a trader to select two or more items that are to be linked and specify linking parameters for those items. Any desired set of items may be linked, and the linking parameters may include price adjustments, order sequencing instructions, automatic/manual execution controls, execution delays commands, and update frequency limits. Upon detecting a bid or offer for a linked item, the systems and methods may then determine a size and a price for each linked item based upon the size and the price of the bid or offer for the first linked item. In this way, the sizes and the prices for the other linked items may be propagated from the size and the price for the first item. Once the size and the price for each item is determined, the systems and methods may submit orders for the items in accordance with the linking parameters.

Abstract: Methods and systems for accessing prospectus data are provided. These methods and systems utilize electronically readable media incorporated into a printed financial prospectus to provide access to data in an electronic format. A suitable device may then be used to read data from the electronically readable media and store the data on a computer system. The information provided by the prospectus therefore contains both human-readable and electronically readable information. The data may be provided in a summary form, in a standardized form, or in any other suitable form in order to facilitate subsequent analysis of the data. The data may also be encrypted while stored in the electronically readable media.
