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 of displaying market information relating to a tradeable object being traded in an electronic exchange having an inside market with a highest bid price and a lowest ask price on a graphical user interface, comprising:

estimating a last traded total sweep quantity determined based on a number of trades executed in a market sweep over a plurality of price levels including a last traded price level for the tradable object;

dynamically displaying a first indicator in one of a plurality of locations in a bid display region, each location in the bid display region corresponding to a price level along a price axis, the first indicator representing quantity associated with at least one order to buy the tradable object at the highest bid price currently available in the market;

dynamically displaying a second indicator in one of a plurality of locations in an ask display region, each location in the ask display region corresponding to a price level along the price axis, the second indicator representing quantity associated with at least one order to sell the tradable object at the lowest ask price currently available in the market;

displaying the bid and ask display regions in relation to a plurality of price levels positioned along the price axis such that upon receipt of an updated inside market each of the plurality of price levels do not change positions, such that the first and second indicators move relative to the price axis; and

dynamically displaying a quantity indicator in a location corresponding to the last traded price level along the price axis, wherein the quantity indicator represents the estimated last traded total sweep quantity.

2. The method of claim 1, further comprising:

displaying a bid order entry region comprising a plurality of locations for receiving commands to send trade orders to buy the tradable object, each location corresponding to a price level of the plurality of price levels; and

displaying an ask order entry region comprising a plurality of locations for receiving commands to send trade orders to sell the tradable object, each location corresponding to a price level of the plurality of price levels.

3. The method of claim 2, wherein the bid order entry region overlaps with the bid display region and the ask order entry region overlaps with the ask display region.

4. The method of claim 2, further comprising:

in response to a selection of a particular location of the bid or ask order entry region by a user input device, setting a plurality of parameters for a trade order relating the tradable object and sending the trade order to the electronic exchange.

5. The method of claim 1, wherein the bid and ask display regions are displayed separately.

6. The method of claim 2, wherein the bid display region, the ask display region, and the order entry regions are displayed vertically or horizontally.

7. The method of claim 1, wherein the market sweep occurs due to a single trade order getting filled at the plurality of price levels.

8. The method of claim 1, wherein the market sweep occurs due to a plurality of trade orders getting filled at the plurality of price levels.

9. The method of claim 1, further comprising:

displaying price levels along the price axis.

10. The method of claim 1, further comprising:

receiving market data that comprises a total traded quantity and a last traded quantity.

11. The method of claim 1, further comprising:

receiving a first market update comprising a first total traded quantity;

receiving a second market update comprising a second total traded quantity; and

computing a difference between the second total traded quantity and the first total traded quantity to estimate the last traded total sweep quantity.

12. The method of claim 11, further comprising:

receiving a third market update comprising a third total traded quantity;

determining a new estimated last traded total sweep quantity based on the second total traded quantity and the third total traded quantity; and

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

13. The method of claim 1, further comprising:

determining a deleted total order quantity based on quantities deleted at the plurality of price levels; and

dynamically displaying a deleted quantity indicator associated with the deleted total order quantity.

14. The method of claim 13, wherein the deleted quantity indicator is displayed in relation to the quantity indicator associated with the estimated last traded total sweep quantity.

15. The method of claim 13, wherein determining the deleted order quantity comprises:

receiving a market update comprising an update for each deleted order at a price;

and using the update for each deleted order to determine the deleted order quantity.

16. The method of claim 13, wherein determining a deleted order quantity comprises:

receiving a market update comprising a decreased order quantity at a price and a total traded quantity; and

estimating the deleted order quantity based on the decreased order quantity and the total traded quantity.

17. The method of claim 13, further comprising:

displaying a deleted order quantity indicator at each of the multiple price levels at which a deleted quantity was detected.

18. The method of claim 1, further comprising:

displaying a last traded quantity region in relation to the bid and ask display regions; and

displaying the quantity indicator associated with the estimated last traded total sweep quantity in the last traded quantity region.

19. The method of claim 1, further comprising:

displaying a last traded quantity indicator in relation to the quantity indicator, wherein the last traded quantity indicator represents a last traded quantity at a price at which the quantity indicator is displayed.

20. A computer readable medium having program code recorded thereon for execution on a computer having a graphical user interface and a user input device, the program code causing a machine to perform the following method steps:

estimating a last traded total sweep quantity determined based on a number of trades executed in a market sweep over a plurality of price levels including a last traded price level for the tradable object;

dynamically displaying a first indicator in one of a plurality of locations in a bid display region, each location in the bid display region corresponding to a price level along a price axis, the first indicator representing quantity associated with at least one order to buy the tradable object at the highest bid price currently available in the market;

dynamically displaying a second indicator in one of a plurality of locations in an ask display region, each location in the ask display region corresponding to a price level along the price axis, the second indicator representing quantity associated with at least one order to sell the tradable object at the lowest ask price currently available in the market;

displaying the bid and ask display regions in relation to a plurality of price levels positioned along the price axis such that upon receipt of an updated inside market each of the plurality of price levels do not change positions, such that the first and second indicators move relative to the price axis; and

dynamically displaying a quantity indicator in a location corresponding to the last traded price level along the price axis, wherein the quantity indicator represents the estimated last traded total sweep quantity.
