Abstract

An improved method for monitoring commodities over an exchange having contracts with multiple markets is provided. Smooth scrolling embodiments in accordance with the present invention will move the pre-shift trading screen to a second position, the post-shift trading screen, which is dependent on which direction the market is moving. As the inside market changes, both the offers and bids change and therefore the inside market changes accordingly. As such, it is desirable for a user to be able to track the changes in the inside market and be able to see the highest bid price and the lowest offer price as the market changes on the user'"'"'s trading screen.

Claims

1. An improved method for monitoring commodities over an exchange having contracts with multiple markets, the method utilizing a software application, comprising:

selecting a particular market based on a pre-determined exchange contract having a price level range;

displaying a trading screen including the inside market for said market, wherein said inside market is defined by prices of the highest bid and the lowest offer;

calculating the center of said inside market, wherein said center of said inside market is determined by averaging the highest bid price and said lowest offer price; and

automatically scrolling said trading screen such that said center of said inside market is substantially centered on the trading screen.

2. The method of claim 1 wherein said automatically scrolling scrolls at a pre-determined shift rate.

3. The method of claim 2 wherein said shift rate is between 2 to 10 pixels per 100 to 1000 milliseconds.

4. The method of claim 3 wherein said trading screen displays a grid having more than one row, each consecutive row corresponding to a consecutive valid price level, wherein said valid price level includes all price levels without regard to whether a market volume exists at those prices, and at least two columns, wherein said columns include a bid column and an offer column.

5. The method of claim 4 wherein said grid includes multiple cells, wherein each cell corresponds to a particular bid or offer at a price level.

6. The method of claim 5 wherein each cell within said grid includes a number that corresponds to the number of bids or offers that exist for a particular price level.

7. The method of claim 5 wherein said cell includes a colored bar, wherein said bar is a graphical representation of the number of bids or offers that exist for a particular price level.

8. The method of claim 7 where the physical size of the graphical representation of said colored bar is calculated using the depth quantity of that price level as the numerator and a grid basis for the denominator.

9. The method of claim 5 wherein each cell within the grid is an individually defined area responsive to pointer action of a user interface cursor over said defined area.

10. The method of claim 9 wherein said cursor automatically stays within the boundaries of the defined area.

11. The method of claim 9 wherein a user action of said user interface cursor on said cell facilitates the submission of an order to an exchange.

12. The method of claim 11 wherein said order is a trade of a commodity over an exchange.

13. An improved method for monitoring commodities over an exchange having contracts with multiple markets, the method utilizing a software application, comprising:

selecting a particular market based on a pre-determined exchange contract having a price level range;

displaying a trading screen including the current market for said market, wherein said current market includes the price level corresponding to the last trade of the commodity;

calculating the center of said current market, wherein said center of said current market is determined by the price level corresponding to the last trade of the commodity; and

automatically scrolling said trading screen such that said current market is substantially centered on the trading screen.

14. The method of claim 13 wherein said automatically scrolling scrolls at a pre-determined shift rate.

15. The method of claim 14 wherein said shift rate is between 2 and 10 pixels per 100 to 1000 milliseconds.

16. The method of claim 15 wherein said trading screen displays a grid having more than one row, each consecutive row corresponding to a consecutive valid price level, wherein said valid price level includes all price levels without regard to whether a market volume exists at those prices, and at least two columns, wherein said columns include a bid column and an offer column.

17. The method of claim 16 wherein said grid includes multiple cells, wherein each cell corresponds to a particular bid or offer at a price level.

18. The method of claim 17 wherein each cell within said grid includes a number that corresponds to the number of bids or offers that exist for a particular price level.

19. The method of claim 17 wherein said cell includes a colored bar, wherein said bar is a graphical representation of the number of bids or offers that exist for a particular price level.

20. The method of claim 19 where the physical size of the graphical representation of said colored bar is calculated using the depth quantity of that price level as the numerator and a grid basis for the denominator.

21. The method of claim 17 wherein each cell within the grid is an individually defined area responsive to pointer action of a user interface cursor over said defined area.

22. The method of claim 21 wherein said cursor automatically stays within the boundaries of the defined area.

23. The method of claim 21 wherein a user action of said user interface cursor on said cell facilitates the submission of an order to an exchange.

24. The method of claim 23 wherein said order is a trade of a commodity over an exchange.

25. An improved method for monitoring commodities over an exchange having contracts with multiple markets, the method utilizing a software application, comprising:

selecting a particular market based on a pre-determined exchange contract having a price level range;

displaying a trading screen including the pre-open market for said market, wherein said pre-open market includes an indicative opening price level prior to the opening of said market;

calculating the center of said pre-open market, wherein said center of said pre-open market is determined by the price level corresponding to the indicative opening price level; and

automatically scrolling said trading screen such that said pre-open market is substantially centered on the trading screen.

26. The method of claim 25 wherein said automatically scrolling scrolls at a pre-determined shift rate.

27. The method of claim 26 wherein said shift rate is between 2 to 10 pixels per 100 to 1000 milliseconds.

28. The method of claim 27 wherein said trading screen displays a grid having more than one row, each consecutive row corresponding to a consecutive valid price level, wherein said valid price level includes all price levels without regard to whether a market volume exists at those prices, and at least two columns, wherein said columns include a bid column and an offer column.

29. The method of claim 28 wherein said grid includes multiple cells, wherein each cell corresponds to a particular bid or offer at a price level.

30. The method of claim 29 wherein each cell within said grid includes a number that corresponds to the number of bids or offers that exist for a particular price level.

31. The method of claim 29 wherein said cell includes a colored bar, wherein said bar is a graphical representation of the number of bids or offers that exist for a particular price level.

32. The method of claim 31 where the physical size of the graphical representation of said colored bar is calculated using the depth quantity of that price level as the numerator and a grid basis for the denominator.

33. The method of claim 29 wherein each cell within the grid is an individually defined area responsive to pointer action of a user interface cursor over said defined area.

34. The method of claim 33 wherein said cursor automatically stays within the boundaries of the defined area.

35. The method of claim 33 wherein a user action of said user interface cursor on said cell facilitates the submission of an order to an exchange.

36. The method of claim 35 wherein said order is a trade of a commodity over an exchange.
