A method and apparatus for bi-directionally auctioning using a computer network, wherein one or more purchase prices and an accumulated purchase quantity of goods at or above each purchase price are displayed in real time. A plurality of buyers participate competitively by registering a purchase price. A higher-price-accumulated purchase quantity is then determined by summing the quantity of similar goods at or above each registered purchase price. Sellers select an acceptable purchase price competitively by referring to each displayed purchase price and higher-price-accumulated purchase quantity. A transaction between a seller selecting first and all buyers who register goods at or above the selected purchase price is consummated. A similar bi-auction system for sellers making bids and a buyer purchasing a higher-price-accumulated quantity of goods is provided by implementing the present invention mutatis mutandis with sellers as buyers and vice-versa. In that case, the higher-price-accumulated amount is at or below each registered sale price.
