Abstract
An automated exchange is provided for trading financial instruments, such as options contracts. The exchange receives a plurality of orders to buy or sell the instruments and stores them in a book memory arranged in order of best price to worst price. The exchange also receives a quotation to purchase or sell a quantity of the instruments at the best price and stores the quotation in the book memory. The orders are traded with the quotation at the best price and when the entirety of the quotation is traded a new quotation is generated and stored in the book memory at a price one or more minimum trading increments worse than the best price. The size of the generated quotation is based on values stored in a quotation table.
