    Patent number: 7797221
    Abstract: A proprietary position display process includes an ask-side display process for displaying, in a multi-column format, an ask-side entry for a specific security that is offered for sale by a market participant on a securities market. This ask-side entry includes a market participant identifier, a lot size, a reserve size, and an ask price. A bid-side display process displays, in a multi-column format, a bid-side entry for the specific security that is sought for purchase by a market participant on a securities market. This bid-side entry includes a market participant identifier, a lot size, a reserve size, and a bid price. The bid-side display process is configured to display the bid-side entry such that it is essentially a mirror image of the ask-side entry.
