  • Publication number: 20210192624
    Abstract: A system and method for prioritized data delivery in an electronic trading environment are described herein. According to one example embodiment, by prioritizing the messages associated with a tradeable object, the bandwidth and system resource usage may be optimally reduced, and any loss of priority content in the messages sent between the network device and the client device may be reduced. An example method includes associating different priority levels with messages comprising market data. Messages containing market information related to the inside market may be associated to a higher priority level. Whereas messages containing market information relating to the quantities at prices outside the inside market may be associated with a lower priority level. Based on the priority level associated with a message, a network device may send the message directly to the client device or store the message in a data structure until a pre-defined condition is satisfied.

  • Patent number: 8822679
    Abstract: A compound useful as a building block for the manufacture of various compounds is represented by Formula A or D. In Formula A and D, z is 0 or 1; Q is a heteroatom; R1 through R11 and Ra through Rf are each independently hydrogen, a substituted or unsubstituted hydrocarbyl group, a substituted or unsubstituted heteroatom containing hydrocarbyl group, or a functional group; d, e and f are each independently 0 or greater; each of A, B and D is independently a carbon atom or a heteroatom; and two or more of R1 though R11, Ra through Rf and Y optionally combine to form a ring. In some embodiments, R8 and R9 combine to form a carbonyl group. In some embodiments, R2 and Y combine to form a ring with the Q atom. In some embodiments, the ring includes at least one double bond.

  • Publication number: 20060265320
    Abstract: A system and methods for processing and charting security exchange trading and market information shows security traders if current transactions originated as buy orders (810) or sell orders (812), and simultaneously indicates traded quantity. Security exchange trading information is received including price, volume and time of each trade. Market information is also received including bids and offers. The security exchange trading and market information is processed simultaneously and displayed as a continuously updated realtime chart (800) depicting the exchange auction process. The chart (800) is formed by plotting each trade at the price traded, and for each plot point shows a distinctive icon indication whether the transaction was initiated by a buyer (810) or seller (812).
