  • Patent number: 8326736
    Abstract: An automated system for matching orders to buy and sell securities including a displayed market where orders are executed at a BBO price and where information about the market is made available to investors and a midpoint matching market for matching buy and sell orders at a predetermined price, namely, the midpoint between the national best bid and offer. The displayed market and the midpoint matching market are linked so that orders submitted to the displayed market are exposed to the midpoint matching market and can be executed at an improved price if a contra order is available on the midpoint matching market.

  • Patent number: 7761364
    Abstract: An automated system for matching orders to buy and sell securities at the midpoint of a best bid and offer (“BBO”), wherein the automated system is adapted to (i) operate on a fully-anonymous and continuous basis, (ii) process multiple, computer-generated orders, of any size, transmitted by algorithmic, program, and other automated trading systems, (iii) automatically match multiple, executable orders according to a priority scheme, and (iv) execute a matching algorithm that maximizes tradable volume when an executable order can not be matched according to the priority scheme. The system may be executed at a server or participant system, or combination of the two.
