Abstract

The lowest trade price for a security within a predetermined period of time is determined, and a momentum liquidity replenishment price is determined by adding the greater of a predetermined price or a predetermined percentage of the last trade price to the lowest trade price for the security for the security within the predetermined period of time. In a similar fashion, another momentum liquidity replenishment price is determined from the highest trading price of the security within predetermined period of time.

Claims

1. A method for managing security trading sweeps comprising:

determining the lowest trade price for a security within a predetermined period of time; and

determining a momentum liquidity replenishment price by adding the greater of a predetermined price or a predetermined percentage of the last trade price to the lowest trade price for the security for the security within the predetermined period of time.

2. A method according to claim 1, wherein the predetermined period of time is 30 seconds.

3. A method according to claim 1, wherein the predetermined price is 25 cents.

4. A method according to claim 1, wherein the predetermined percentage is one percent of the last trade price.

5. A method for managing security trading sweeps comprising:

determining the highest trade price for a security within a predetermined period of time; and

determining a momentum liquidity replenishment price by subtracting the greater of a predetermined price or a predetermined percentage of the last trade price from the highest trade price for the security for the security within the predetermined period of time.

6. A method according to claim 5, wherein the predetermined period of time is 30 seconds.

7. A method according to claim 5, wherein the predetermined price is 25 cents.

8. A method according to claim 5, wherein the predetermined percentage is one percent of the last trade price.

9. A method for executing a securities order comprising:

determining a momentum liquidity replenishment price;

receiving a limit order to buy with a price that is equal to or greater than the momentum liquidity replenishment price;

determining a best offer price and size associated with the best offer price;

executing a portion of the limit order at the best offer price;

sweeping the limit order at the momentum liquidity replenishment price against orders on a limit order book; and

changing a quote from fast to slow.

10. A method according to claim 9, wherein a portion of the limit order is equal to the size associated with the best offer price.

11. A method according to claim 9, wherein sweeping the limit order completely fills the limit order.

12. A method according to claim 9, wherein sweeping the limit order partially fills the limit order leaving unexecuted size.

13. A method according to claim 9, further comprising:

waiting for the momentum liquidity replenishment price to reset; and

automatically changing the quote from slow to fast.

14. A method according to claim 9, further comprising:

automatically changing the quote from slow to fast a predetermined number of seconds after changing the quote from fast to slow.

15. A method according to claim 14, wherein the predetermined number of seconds is ten seconds.

16. A method according to claim 9, further comprising:

calculating a remaining unexecuted size of the limit order; and

quoting the remaining unexecuted limit order size at the momentum liquidity replenishment price.

17. A method for executing a securities order comprising:

determining a momentum liquidity replenishment price;

receiving a limit order to sell with a price that is equal to or less than the momentum liquidity replenishment price;

determining a best bid price and size associated with the best bid price;

executing a portion of the limit order at the best bid price;

sweeping the limit order at the momentum liquidity replenishment price against orders on a limit order book; and

changing a quote from fast to slow.

18. A method according to claim 17, wherein a portion of the limit order is equal to the size associated with the best bid price.

19. A method according to claim 17, wherein sweeping the limit order completely fills the limit order.

20. A method according to claim 17, wherein sweeping the limit order partially fills the limit order leaving unexecuted size.

21. A method according to claim 17, further comprising:

waiting for the momentum liquidity replenishment price to reset; and

automatically changing the quote from slow to fast.

22. A method according to claim 17, further comprising:

automatically changing the quote from slow to fast a predetermined number of seconds after changing the quote from fast to slow.

23. A method according to claim 22, wherein the predetermined number of seconds is ten seconds.

24. A method according to claim 17, further comprising:

calculating a remaining unexecuted size of the limit order; and

quoting the remaining unexecuted limit order size at the momentum liquidity replenishment price.

25. A method for executing a securities order comprising:

determining a momentum liquidity replenishment price;

receiving a limit order to buy with a price that is equal to or greater than the momentum liquidity replenishment price;

determining a best offer price and size associated with the best offer price;

executing a portion of the limit order at the best offer price;

sweeping the limit order against orders on a limit order book;

determining that no orders remain on the limit order book priced less than the momentum liquidity replenishment price; and

changing a quote from fast to slow.

26. A method according to claim 25, further comprising:

determining a new momentum liquidity replenishment price; and

changing the quote from slow to fast.
