Abstract: A method and system for viewing and trading futures and other tradeable objects. The invention includes improved user interfaces for use with trading systems that allows users to more efficiently execute and manage trades. A dynamic price ladder allows a trader to see price gaps while remaining in a dynamic mode. The “sticky cells” feature prevents user errors which can occur when the display updates causing the cell under the mouse pointer to move up or down. Particular portions of the display can be color coded to provide a user with a easy way to determine market trends. A static working order screen allows a trader to visually see working orders from closest to furthest away from the market and can also allow for orders to be cancelled.

Abstract: A post-trade aggregation system includes an allocation middleware interface, which interacts with data interface to allocate and settle trades. An order management system receives a trade order on behalf of a customer and causes apportionment of the trade into a plurality of smaller orders to be transmitted to a plurality of order destinations directly (e.g. via the FIX protocol). The post-trade aggregation system includes an allocation middleware interface which receives the individual trade executions from the plurality of order destination and compresses them into a single average-priced block. The allocation middleware interface then transmits the single average-priced block to be cleared by a designated clearing agent and allocates the single average-priced block into one or more custodian accounts.

Abstract: The present invention relates generally to electronic trading systems. More particularly, the present invention relates to systems and methods for providing, within an electronic trading process, real-time or near real-time pre- and post-trade analytics to assist traders make the decision of how to trade electronically a particular tradeable asset. Pre- and post-trade analytics can be displayed to a trader without affecting their workflow. Moreover, pre- and post-trade analytics can be used to make trading recommendations, to select or modify a trading strategy, to select and or modify trading destinations, brokers, algorithms or venues, and/or to automatically generate and transmit electronic trade orders or to effect trades.

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 trading platform computer system 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.
