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.

Abstract: An aggregated display process includes a display process for displaying, in a multicolumn format, an entry for a specific security that is sought for purchase or offered for sale by a market participant on a securities market. These entries, which can be bid-side entries or ask-side entries, each include a market participant identifier, a lot size, and a bid or ask price. The display process includes a tabular display process for simultaneously displaying multiple entries in a table. An aggregate calculation process generates an aggregate value for a specific entry. This aggregate value is equal to the lot size of the specific entry summed with the lot sizes of all preceding entries included in the table.

A user order execution process executes an order concerning the group of selected shares.
