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”.

An index generally includes two index components. A first index component tracks a basket of futures contracts including at least two or more sets of futures contracts with different delivery months spread over a selected time period. The basket of futures contracts being rolled as certain futures contracts in the basket approach expiration. A second index component tracks a roll differential that indexes to a starting value periodically adjusted by a differential substantially equal in value to a delta between a first value of the futures contracts in the basket approaching expiration and a second value of futures contracts being rolled into a delivery period subsequent to the ending delivery period of the selected time period. The index is priced at least in part based on index values of the basket of futures contracts and the roll differential. Various financial instruments may be created to track the price of the index.
