Claim:
A computerized method for the trading, buying or selling, of lists of independent items at independent quantities between an initiator and multiple respondents, the initiator and multiple respondents having an established relationship, the method comprising: a) providing, by an initiator client device, a list creation user interface to enable entry by the initiator of a list of items of buying or selling interest with select volumes; b) transmitting, by the initiator client device, the list of items to one or more respondent client devices; c) providing, by the one or more respondent client devices, a list response user interface to enable entry by the respondents of offers or bids on a single item, multiple items, or all items on the list, on an item-by-item basis at independent spreads, yields, discount margins or prices in the volumes requested; d) transmitting, by the one or more respondent client devices that received entry of offers or bids, the entered offers or bids to the initiator client device; e) providing, by the initiator client device, a list trade user interface to enable the initiator to view and trade on (by hitting or lifting) a single item, multiple items, or all items on the list, on an item-by-item basis at independent and select spreads, yields, discount margins or prices for each item where at least one offer or bid was received; f) providing, by the initiator client device, a list pricing user interface to enable the initiator to request from the one or more respondent client devices that transmitted offers or bids a final price for each traded item where at least one offer or bid was received and verifying whether at least one of: spread to benchmark, benchmark spot price and benchmark spot yield have already been agreed for securities that trade on yield or discount margin; g) determining, by the initiator client device, a benchmark spot price at the request of the initiator using a set of pre-defined algorithms to retrieve and calculate a benchmark spot price when at least one of: spread to benchmark, benchmark spot price and benchmark spot yield have not already been agreed for securities that trade on yield or discount margin, wherein the initiator client device presents the determined benchmark spot price to the initiator in a spotting user interface; h) providing, by the initiator client device, a list complete notification that each item on the list has reached a final state in which the item was traded or not traded; and i) providing, by the one or more respondent client devices that transmitted offers or bids, a list complete notification that each item on the list has reached a final state in which the item was traded or not traded.
