Patent ID: 8392315

Claim:
A method comprising: displaying, by a computing device, a plurality of axially aligned price levels each identifying a price of a tradable object traded at an electronic exchange; dynamically displaying, by the computing device, at least one order indicator identifying at least one order for the tradable object pending at the electronic exchange, the at least one order indicator being displayed at a price level of the plurality of axially aligned price levels identifying a price for the at least one order for the tradable object; determining, by the computing device, a lowest traded price for the tradable object, the lowest traded price being determined for a user-selected time period based on any of a last traded price received from the electronic exchange, a lowest traded price received from the electronic exchange, and a combination thereof; dynamically displaying, by the computing device, a lowest traded price indicator at a lowest traded price level of the plurality of axially aligned price levels identifying the lowest traded price, the lowest traded price indicator being movable relative to the plurality of axially aligned price levels according to any of the last traded price received from the electronic exchange, the lowest traded price received from the electronic exchange, and a combination thereof; determining, by the computing device, a highest traded price for the tradable object, the highest traded price being determined for the user-selected time period based on any of the last traded price received from the electronic exchange, a highest traded price received from the electronic exchange, and a combination thereof; dynamically displaying, by the computing device, a highest traded price indicator at a highest traded price level of the plurality of axially aligned price levels identifying the highest traded price, the highest traded price indicator being movable relative to the plurality of axially aligned price levels according to any of the last traded price received from the electronic exchange, the highest traded price received from the electronic exchange, and a combination thereof; and dynamically displaying a column indicator by the computing device, the column indicator being displayed relative to each price level of the plurality of axially aligned price levels between the lowest traded price level of the plurality of axially aligned price levels and the highest traded price level of the plurality of axially aligned price levels, where the column indicator changes relative to the plurality of axially aligned price levels between the lowest traded price level of the plurality of axially aligned price levels and the highest traded price level of the plurality of axially aligned price levels according to changes in any of the lowest traded price level and the highest traded price level.
