    摘要: An apparatus for processing trade orders comprises a processor and memory that stores first and second orders. The first order is associated with a product and comprises displayed and reserved quantities. The second order is associated with the product and comprises displayed and reserved quantities. The processor is coupled to the memory and receives a counterorder associated with the product. The processor fills the displayed quantity of the first order with a corresponding portion of the counterorder, and the displayed quantity of the second order with a corresponding portion of the counterorder. The processor allocates a first additional portion of the counterorder to the first order. The first additional portion is based at least in part on a ratio of the displayed quantity of the first order to a sum of the displayed quantity of the first order and the displayed quantity of the second order.

    摘要: Methods and systems are presented for analyzing transactions conducted through user accounts with an online service provider based on graph analysis. A graph is generated based on a set of seed accounts that are determined to be involved in suspicious activities. The graph includes a set of seed nodes representing the seed accounts, and a set of nodes representing user accounts that are connected to the set of seed accounts in downstream transactions. A random walk traversal based on multiple dimensions is performed on the graph to determine nodes that are closely related to the set of seed nodes. Transactions conducted through the seed accounts and accounts corresponding to nodes that are closely related to the set of seed nodes are analyzed to detect any malicious activities. The graph may also be presented according to a layered hierarchical structure for better visualization of transaction flows through the accounts.

    摘要: System, method, and program products offer flexibility to the rather rigid way of trading in an electronic trading system. Orders for a tradeable object may typically get matched according to set terms and/or conditions at an electronic exchange. A trader may log onto the electronic exchange to trade the tradeable object, and may choose to display and trade the tradeable object according to a different set of terms and/or conditions. As such, the market data sent to the trader from the exchange is converted to a format according to the trader's selection, so that it may be presented to the trader in this format. Transaction messages sent to the exchange from the trader are converted to the format readable by the matching process, so that it can process the messages. Other features and advantages are described herein.
