The present technology relates to distributed computerized exchange systems for trading of financial instruments. In particular it relates to a passive matching engine and an active matching engine that cooperates in handling data messages such that less bandwidth is used and so that improvement in latency can be achieved.

24 hours global low latency computerized exchange system

A computer system includes a memory to store a first set of data including data processing requests or data processing execution results and computer hardware to determine an input relating to a load and filter the first set of data to extract, based on the input relating to the load, a second set of data from the first set of data, thereby leaving a remaining set of data. The second set of data and the remaining set of data both include data processing requests or data processing execution results input or generated by the computer system. The computer hardware prepares electronic messages to be transmitted over a communications network to a plurality of remote user terminals. The electronic messages contain the second set of data but do not contain the remaining set of data. The computer hardware controls a frequency at which the electronic messages containing the second set of data are to be transmitted over the communications network based on the input relating to the load.

System and method for adaptive information dissemination

A user terminal for communicating with a computer server is operated on behalf of a first user (a second user terminal is operated on behalf of a second user). The user terminal transmits to the computer server pre-trade information including an order and receives first offset information that indicates a first price offset value, which is different from a second price offset value sent to the second user terminal. The terminals receive a single message from the server that indicates a market price but does not include the first price offset value or the second price offset value. The user terminal modifies the market price using the first price offset value to obtain a first actual price different from a second actual price corresponding to a modification of the market price based on the second price offset value.

Reducing data traffic in a computerized trading system

A method of processing exchange system trading data is disclosed. In one embodiment, the method comprises receiving an order data message from a matching engine of an automated exchange. The order data message has first data format and it also comprises identification information associated with a trading entity. The received data message is then converted into a new data message of a new data format, which is different from the data format of the received order data message. Also, the trading entity from which the received order data message is originating is identified. Subsequently, the new data message having the new data format can be transmitted to a plurality of client devices associated with the identified trading entity. This may allow for all, or at least a majority of client devices, of the identified trading entity to get an overview of the total order activity of the identified trading entity.

Methods and arrangements for an automated exchange system

System for and a method of transmitting data in a central trading system

In a distributed network, there are different data rates on different connections between a central computer system and remote terminal. The central computer system includes one or more sets of data to be distributed to the remote terminals by extracting subsets of data from the set(s) of data. The subsets of data are distributed to selected groups of remote terminals based on an infrastructure load in order to adaptively distribute the data.

A computerized trading system receives buy and sell trade orders in financial instruments traded in the central trading system from user terminals connected to the central trading system is provided. Users and/or user terminals are associated with different offset spread values. The trading system transmits price information and associated offset spread values to different user terminals. Each of the user terminals displays an actual price for the instrument that corresponds to the combined price information and associated offset spread value.

The technology is suitable for any kind of distributed networks having different data rates on different connections and a computer system where the data to distribute is created. The system comprises one or more supersets of data to be distributed to client computers by extracting subsets of data from the superset(s) of data. Thereafter, the subsets of data are distributed to selected groups of clients based on information about the network architecture. This provides an efficient way of distributing data without having to duplicate distributed data. In example implementations, subsets may be distributed to clients based on a counter performance or a data rate of a client's connection to the computer system.
