Abstract: An interface for trading multiple tradeable objects includes a price axis or scale. A first indication of quantities represented in a market for a first tradeable object is displayed in association with the price axis or scale. A second indication of quantities represented in the market for a second tradeable object is displayed in association with the price axis or scale. The first tradeable object may be different than the second tradeable object. Alternatively, the first tradeable object and the second tradeable object may be the same, but the indications of quantity may be provided from different sources, such as different exchanges.

Abstract: A trading system is described herein for hosting a collection of one or more electronic exchanges. The collection of electronic exchanges may be made up of separately designated exchanges under one or more authorizing and regulating bodies. The trading system receives from traders bids to purchase and offers to sell a tradeable object listed at one of the electronic exchanges. Then, the trading system directs the bids and offers to the appropriate exchange where the bids and offers may be automatically matched in the corresponding market. The trading system may also be used to take actions in one or more markets that are internal and external to the trading system on behalf of a trader using preprogrammed trading instructions.

Abstract: A system and method are provided for trading multiple tradeable objects. One example method includes displaying at least one combined quantity indicator representing a combined quantity associated with at least two tradeable objects, detecting an input associated with an order for a predetermined order quantity in relation to one of the combined quantity indicators, and allocating the order quantity between the at least two tradeable objects using at least one quantity allocation rule. In one example embodiment, a plurality of quantity allocation rules can be user-configurable, and different rules can be defined and applied in relation to different order types.

Abstract: A system and associated methods are provided for intelligent placement and movement of orders in an electronic trading environment. According to one example method, in addition to submitting a leg order at a calculated price level, additional orders, queue holder orders, are submitted for the leg order at prices either below or above the calculated price level. Based on this configuration, if the conditions change such that it is necessary to re-price the leg order, there will be already an order resting in the exchange order book at the re-calculated price that can be used in the strategy. Upon re-pricing the leg order, one or more additional queue holder orders will be placed in the market. Other tools are provided as well.

Abstract: A data distribution system and method are described herein to improve the distribution of market information to subscribing client devices. Market information updates are provided to subscribing devices over a communication link every time a change in the market occurs. If a bandwidth limitation is reached on the communication link, the preferred embodiments switch to a second mode of transmission such that the market information updates are provided only at predetermined intervals. The preferred embodiment monitors the bandwidth consumption to determine what mode of transmission to apply, and in response, it can dynamically change between modes of transmission. By dynamically adjusting the mode of transmission to comport with the current network bandwidth, the preferred embodiments may provide a network friendly, data intensive, and fast response market information feed.

Abstract: System and methods for a connection proxy server are described. According to an example method described herein, a connection proxy server stores subscription, product tables as well as other downloads that are provided to a client terminal during initialization stage as well as later during a trading session. Upon detecting that a connection between the client terminal and a gateway is lost, the connection proxy maintains a communication session created for the client terminal at the gateway and receives data intended for the client terminal. If the connection is re-established between the client terminal and the gateway during a predetermined period of time, the connection proxy provides the stored data to the client terminal thus avoiding a surge in processing resources at the gateway due to the necessary downloads.

Abstract: A system and method are provided that, among other things, can reduce the burden on receiving computers, increase data throughput, reduce system failure, and provide components of a scalable and flexible network architecture. Specifically, the system and method provide a multichannel-multicast network environment for use in dynamically assigning data to channels. This configuration is particularly useful in a trading network environment, as it effectively performs channel reassignments in a way not to disturb the receipt of the underlying data. While the example embodiments described herein pertain to electronic trading, the principles of the present invention may be equally applied in other environments where the advantages presented herein are beneficial.
