Abstract: A computer display of a exchange traded option trading system includes capabilities to sort the information received from the exchange to provide the liquidity provider with optimum trading opportunities based on the liquidity provider's portfolio. Various displays are provided. A first display provides a comparison of theoretical values to market place pricing values for tradable interests in the portfolio and displays in sorted order the tradable interests for which the values are the most out of line. Trade entry is possible directly from the display. In another display, the pricing data of tradable interests in the portfolio as received from a primary exchange are compared to pricing data on other exchanges, and a listing is provided of the tradable interests in which the values are crossed, are the same (locked) or are one trade increment away from one another. Trade entry is possible directly from this display.
