FIELD OF THE INVENTION
 This invention relates to providing electronic information over a computer network. More specifically, it relates to a method and system for providing electronic information for multi-market electronic trading.
BACKGROUND OF THE INVENTION
 The trading of stocks, bonds and other financial instruments over computer networks such as the Internet has become a very common activity. In many countries of the world, such stocks, bonds and other financial instruments are traded exclusively over computer networks, completely replacing prior trading systems such as "open outcry" trading in trading pits.
 Trading of stocks, bonds, etc. typically requires multiple types of associated electronic information. For example, to trade stocks electronically an electronic trader typically would like to know an asking price for a stock, a current bid price for a stock, a bid quantity, an asking quantity, current information about the company the trader is trading such as profit/loss information, a current corporate forecast, current corporate earnings, etc.
 For an electronic trader to be successful, the multiple types of associated electronic information has to be supplied in real-time to allow the electronic trader to make the appropriate decisions. Such electronic information is typically displayed in multiple windows on a display screen.
 In addition, when an electronic trader executes an electronic trade over a computer network, the computer network must respond to the order request in real-time in an appropriate, accurate, consistent manner. However, such electronic trade data is typically sent and received in a same data stream that supplies the multiple types of electronic information.
 There are however a number of problems with electronic trading. One problem is that supplying multiple types of electronic information along with electronic trading information on the same data streams significantly increases the computations required on a target device being used by an electronic trader and by servers being used by electronic trading providers to separate the information.
 Another problem is that such data streams may also include information for national as well as international markets. Desired data from such data streams needs to be accurately separated and displayed by a target device.
 Another problem is that sending multiple types of electronic information over a computer network requires a large bandwidth and may significantly affect the performance of the computer network. As the performance of the computer network slows down, the flow of electronic infor
mation is also affected. Electronic traders may then not be able to make the appropriate trading decisions at the appropriate moment of time due to slow information flow.
 Another problem is that displaying multiple types of electronic information in a coherent format that can be used by an electronic trader is difficult. In many instances such multiple types of electronic information are displayed in multiple windows on a computer display with multiple colors in general formats that do not meet the needs of all electronic traders.
 Another problem is that most existing electronic trading systems do not allow an electronic traders to see their current positions, as well as their current profit and loss and commissions in real-time during a trading day. In most instances, such information is not available until a day following a current trading day.
 Another problem is that most existing electronic trading systems do not provide the ability to display multiple types of electronic information for national and international markets in a format usable by electronic traders.
 Thus, it is desirable to solve some of the problems associated with supplying multiple types of electronic information along with electronic trading information on the same data streams.
SUMMARY OF THE INVENTION
 In accordance with preferred embodiments of the present invention, some of the problems with supplying multiple types of electronic information along with electronic trading information on the same data streams are overcome. A method and system for providing electronic information for multi-market electronic trading is presented.
 The method and system may improve an infrastructure used by electronic traders over a computer network by splitting one or more data streams from one or more electronic trading exchanges with multiple types of electronic trading information into plural separate data streams that can be selectively requested, displayed and used by a user. The plural separate data streams and can requested, displayed and used faster and more efficiently than an entire data stream including all the multiple types of electronic trading information. Less bandwidth is required to send the separate data streams and the separate data streams require less processing power when used on a target device.
 The foregoing and other features and advantages of preferred embodiments of the present invention will be more readily apparent from the following detailed description. The detailed description proceeds with references to the accompanying drawings.

DETAILED DESCRIPTION OF THE
 FIG. 1 is a block diagram illustrating an exemplary electronic trading system 10. The exemplary electronic information updating system 10 includes, but is not limited to, one or more target devices 12,14,16 (only three of which are illustrated). However, the present invention is not limited to these target electronic devices and more, fewer or others types of target electronic devices can also be used.
 The target devices 12, 14, 16 are in communications with a communications network 18. The communications includes, but is not limited to, communications over a wire connected to the target network devices, wireless communications, and other types of communications using one or more communications and/or networking protocols.
 Plural server devices 20, 22, 24 (only three of which are illustrated) include one or more associated databases 20', 22', 24'. The plural network devices 20,22,24 are in communications with the one or more target devices 12, 14,16 via the communications network 18. The plural server devices 20, 22, 24, include, but are not limited to, World Wide Web servers, Internet servers, file servers, other types of electronic information servers, and other types of server network devices (e.g., edge servers, firewalls, routers, gateways, etc.).
 The plural server devices 20,22,24 include, but are not limited to, servers used for electronic trading exchanges, servers for electronic trading brokers, servers for electronic trading information providers, etc.
 The one or more target devices 12, 14, 16 may be replaced with other types of devices including, but not limited to, client terminals in communications with one or more servers, or with personal digital/data assistants (PDA), laptop computers, mobile computers, Internet appliances, two-way pagers, mobile phones, or other similar desktop, mobile or hand-held electronic devices. Other or equivalent devices can also be used to practice the invention.
 The communications network 18 includes, but is not limited to, the Internet, an intranet, a wired Local Area Network (LAN), a wireless LAN (WiLAN), a Wide Area Network (WAN), a Metropolitan Area Network (MAN), a Public Switched Telephone Network (PSTN) and other types of communications networks 18.
 The communications network 18 may include one or more gateways, routers, or bridges. As is known in the art, a gateway connects computer networks using different network protocols and/or operating at different transmission capacities. A router receives transmitted messages and forwards them to their correct destinations over the most
efficient available route. Abridge is a device that connects networks using the same communications protocols so that information can be passed from one network device to another.
 The communications network 18 may include one or more servers and one or more web-sites accessible by users to send and receive information useable by the one or more computers 12. The one ore more servers, may also include one or more associated databases for storing electronic information.
 The communications network 18 includes, but is not limited to, data networks using the Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Internet Protocol (IP) and other data protocols.
 As is know in the art, TCP provides a connectionoriented, end-to-end reliable protocol designed to fit into a layered hierarchy of protocols which support multi-network applications. TCP provides for reliable inter-process communication between pairs of processes in network devices attached to distinct but interconnected networks. For more information on TCP see Internet Engineering Task Force (ITEF) Request For Comments (RFC)-793, the contents of which are incorporated herein by reference.
 As is known in the art, UDP provides a connectionless mode of communications with datagrams in an interconnected set of computer networks. UDP provides a transaction oriented datagram protocol, where delivery and duplicate packet protection are not guaranteed. For more information on UDP see IETF RFC-768, the contents of which incorporated herein by reference.
 As is known in the art, IP is an addressing protocol designed to route traffic within a network or between networks. IP is described in IETF Request For Comments (RFC)-791, the contents of which are incorporated herein by reference. However, more fewer or other protocols can also be used on the communications network 18 and the present invention is not limited to TCP/UDP/IP.
 An operating environment for the devices of the exemplary electronic trading system 10 include a processing system with one or more high speed Central Processing Unit(s) ("CPU"), processors and one or more memories. In accordance with the practices of persons skilled in the art of computer programming, the present invention is described below with reference to acts and symbolic representations of operations or instructions that are performed by the processing system, unless indicated otherwise. Such acts and operations or instructions are referred to as being "computerexecuted,"" CPU-executed," or "processor-executed."
 It will be appreciated that acts and symbolically represented operations or instructions include the manipulation of electrical signals by the CPU or processor. An electrical system represents data bits which cause a resulting transformation or reduction of the electrical signals or biological signals, and the maintenance of data bits at memory locations in a memory system to thereby reconfigure or otherwise alter the CPU's or processor's operation, as well as other processing of signals. The memory locations where data bits are maintained are physical locations that have particular electrical, magnetic, optical, or organic properties corresponding to the data bits.
