This method groups multiple merchandises (products / services) and multiple traders (buyer / sellers / carriers) that share similar properties with a Merchandise Group ID (MGID) and a User Group ID (UGID), respectively. Each MGID and UGID represents one Merchandise Group and Trader Group, respectively. Different MGIDs and UGIDs represent different merchandise and trader groups. The method also utilize a multi-party matching mechanism to trade Merchandise Groups among Trader Groups by having grouped buyers / sellers / carriers place bid / ask / cAsk offers on both the merchandise and any shipping services required to fulfill the transaction. Based on offers received, the system calculates Gap Values in real-time to determine if deals can be closed. Like stock tickers, MGID enables grouped merchandise to be traded like stocks. UGID enables grouped traders to trade desired merchandise with acceptable counterparties through matching both MGIDs and UGIDs. Based on the grouping, matching and gap value calculating mechanism, this method changes “Instance Trading” into “Group Trading”.

A margin requirement is computed while trading. The margin requirement may be calculated while trading because the preferred system takes into account working orders to generate the margin requirement. The on the fly possibility allows the preferred system to provide pre-trade risk calculations, but can also be used to provide post-trade calculations. A generic spread number and the maximum number of outright positions are determined. Using the spread positions and the maximum number of outright positions, a spread margin and an outright margin are calculated, which when summed provide a total margin requirement. Limits based in part on the total margin requirement may be imposed on one or more traders.

Systems and methods for providing traders an opportunity to improve prices for an item trading in an active market are provided. After a trader HITS or LIFTS a bid or offer, a market becomes active. When the market is active, traders can submit orders that improve on the price of the current market price of an item. Whenever a price improvement order is currently available for use in a transaction order, a price improvement indicator is displayed to indicate to other traders that price improvement is occurring. When a price improvement order is used to fill a transaction order, a portion of the difference between the market price and the price improvement price may be divided between the trader associated with the price improvement order, the trader associated with the transaction order, and the system host.

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.

A system and method for allowing market participants to evaluate the likelihood of finding hidden volume. The model can predict hidden volume and assess the probability that a market order will be executed within the spread and better than the mid-quote. The cost per immediate execution can be assessed.

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.

A method and system conduct an auction for advertising across multiple markets. A first market conducts a first auction for a first advertising impression. A first bid is selected as the auction winner and a ratio is computed as the first bid plus a spread to the second highest bid. The price to be paid is the lower of the first bid or the first bid multiplied by the ratio. The first bid, second bid, and spread are transmitted to a second market for a second advertising impression auction. The second market respects the rules of the first market's auction where such that if the first bid is selected as the winner, a ratio is computed as the first bid plus the spread to the next highest bid. The price to be paid for the second impression is the first bid multiplied by the new ratio.
