Abstract: Systems and methods are provided for maintaining neutrality while trading a list of securities using an algorithmic trading facility coupled with at least one destination. This destination includes at least one alternative trading system (ATS). This facility is coupled, via an electronic data network, to a plurality of trading clients, and configured to receive a trade request to trade a list of securities from a trading client. This request includes user defined trading constraints that are used to generate and transmit trade orders to at least one ATS. The orders are transmitted based on trading data related to the destinations, the trade list, and the trading constraints. The facility can identify each executed trade corresponding to the trade orders and calculate a trade imbalance. The facility can determine whether the trade imbalance exceeds the trading constraints, and reallocate one or more of said submitted orders based on this determination.

Abstract: A method and system for performing a batch auction whereby a series of orders, according to a variety of predetermined order types, are generated by qualified market participants and communicated to an auction system. The auction system takes into account each order and its impact upon relative supply and demand to determine by a preset algorithm a price and share transaction quantity. Trades are executed at the price, and a portion of the transaction quantity is allocated to each investor on a fair basis dependent upon their initial orders. In embodiments of the present invention, the auction system uses a computer system or network designed to automatically perform one or more steps of the above method. Such a system is preferably connected to one or more ECNs such that non-executed shares can be automatically sent to outside sources for execution.

Abstract: Systems, methods, and computer program products are provided for integrating an order management system with execution facilities. According to the invention, at least one trade in an order management system (OMS) is selected to be or otherwise made available to be worked in an execution platform (EP). Order information in the OMS, corresponding to the at least one trade, is sent from the OMS to the EP without committing the underlying shares for the trade. It is determined if the EP is attempting to generate, or has generated, an executable trade order corresponding to the order information received from the OMS.

Abstract: A system and method for rebalancing separately managed accounts utilizing sub-models. Sub-models can be generated automatically by analyzing the restrictions that exist on the individual accounts, or created manually by identifying particular stocks that might fall within a particular industry, sector or other arbitrary classification. An account can be classified as belonging to one or more sub-models. These sub-models allow for a more efficient rebalancing process by allowing transaction decisions to be made according to a particular sub-model rather than at the level of each individual account. These sub-models also allow for more efficient monitoring of large numbers of accounts by allowing analysis of account drift according to both restrictions associated with the account as well as the account's master model portfolio, rather than solely relative to the account's master model portfolio without incorporating the account's restrictions.

Abstract: A system and method for detecting an abnormal trading condition of a security uses real-time and estimated values of one or more variables associated with the condition of the security to generate one or more analytic metrics that are compared to empirical distributions based on one or more peer groups for the security. An indicator can then be displayed to a trader as an indication of the abnormal condition.
