Abstract

Trading software may receive trading information from an exchange. The trading software may use the trading information to compute an estimate of last traded total sweep quantity. The trading software may also display the last traded total sweep quantity on a trading screen.

Claims

1. A method for displaying trading information, the method comprising:

receiving one or more updates for a tradeable object from an exchange, wherein the one or more updates provide information about a market state of the tradeable object at the exchange;

using the information from the one or more updates to determine that trades have been executed over a plurality of different price levels for the tradeable object;

determining a last traded total sweep quantity, wherein the last traded total sweep quantity indicates a total quantity value corresponding to a number of trades executed over the plurality of different price levels including a last traded price level for the tradeable object; and

displaying the last traded total sweep quantity on a trading screen.

2. A computer readable medium having stored therein instructions for causing a central processing unit to execute the method of claim 1.

3. The method of claim 1, further comprising:

determining a second last traded total sweep quantity; and

displaying the second last traded total sweep quantity, wherein the last traded total sweep quantity is associated with a first price level, and wherein the second last traded total sweep quantity is associated with a second price level.

4. The method of claim 3, further comprising:

fading out the last traded total sweep quantity over a predetermined period of time; and

fading-out the second last traded sweep quantity over the predetermined period of time.

5. The method of claim 1, wherein the one or more updates comprise a total traded quantity and a last traded quantity.

6. The method of claim 1, wherein determining the last traded total sweep quantity comprises:

receiving a first update, wherein the first update comprises a first total traded quantity;

receiving a second update, wherein the second update comprises a second total traded quantity; and

determining the last traded total sweep quantity by computing a difference between the second total traded quantity and the first total traded quantity.

7. The method of claim 1, wherein the one or more updates comprise a last traded quantity for a last traded price, the method further comprising displaying the last traded quantity.

8. The method of claim 1, further comprising:

determining a deleted order quantity; and

displaying the deleted order quantity.

9. The method of claim 1, further comprising removing the last traded total sweep quantity from the trading screen after a predetermined period of time.

10. The method of claim 1, further comprising fading-out the last traded total sweep quantity over a predetermined period of time.

11. The method of claim 1, wherein determining the last traded total sweep quantity comprises:

wherein the one or more updates comprise last traded quantities at last traded prices, and

determining the last traded total sweep quantity by computing a sum of the last traded quantities.

12. The method of claim 1, further comprising performing a single update of the trading screen using the updates.

13. The method of claim 1, further comprising:

dynamically displaying a quantity indicator associated with at least one order to buy the tradeable object in relation to a static axis of prices;

dynamically displaying a quantity indicator associated with at least one order to sell the tradeable object in relation to the static axis of prices; and

dynamically displaying a quantity indicator associated with the last traded total sweep quantity in relation to the static axis of prices.

14. The method of claim 13, further comprising the step of displaying a region for receiving a command to enter an order for the tradeable object.

15. The method of claim 13, wherein the static axis of prices is displayed.

16. The method of claim 13, wherein the static axis of prices is vertically disposed.

17. The method of claim 13, wherein the static axis of prices is horizontally disposed.

18. The method of claim 1, further comprising:

using the information from the one or more updates to determine that trades have not been executed over a plurality of different price levels for the tradeable object; and

displaying a last traded quantity at a last traded price level on the trading screen.
