THE TECHNOLOGICAL CHARACTERISTICS OF TRADING SYSTEM OF SHANGHAI GOLD EXCHANGE

Consummate operation function system

The gold trading system is trading transaction-oriented, including services such as gold trading, capital settlement, and gold delivery, and is a typically key task-oriented operational application system. The system consists of four sub-systems of trading, settlement, storage, and information. Each system is independent, and it delivers data, instruction, and request through the standard interface.

Through the special line net connection with the settlement bank, the gold trading system offers the real time capital settlement service. The member can transfer the capital into the account opened in the settlement bank by the exchange from the account opened in other place.

In addition, computers are installed and connected to the exchange in all appointed stores. The input and output information of the member is delivered directly from the storage system to the exchange.

Flexible design, full consideration of the future development of business

Considering that the preliminary period of the market construction, that gold has not been standardized and specified, and that there exist various exchange demands among members, gold trading system designed diversified exchange modes, among which the standard gold adopted simple and effective match pattern, and the non-standard gold may adopt the mode of inquiry or auction.

Meanwhile, varieties like silver and platinum are taken into consideration too in order to adapt to the future development of the exchange. The data design structure and the processing flow take the accumulation and combination of exchange instrument, types, and modes.

According to the existing design, the preliminary period of exchange will follow the principle of trading underlying real background in order to reduce the venture of exchange. Considering the possibly introduced types like three months long-date delivery of merchandise on hand, exchange system also designed the managing pattern of proportion reserve.Besides, the system also provides multi-level management, various place exchange, diversified settlement modes, and flexible parameter setting for the purpose of adjustment in the processing approach of the preliminary period of the exchange.

The security of the system

Gold exchange system is going to be established on the special financial exchange net of the China Foreign Exchange Trade System, which guarantees the security of system. Additionally, each processing step designs the security measures to assure the security and reliability of the system.

(1) To enforce the strict identification and accredit of the entity and customers in the system to prevent the information being filch and tamper, imposture, or denial. (2) The collection of communication data is encrypted. (3) The limitation of accredit on important exchange.(4) The log file of processing exchange and settlement is set up to make real-time record of all the operator in the exchange and the operation of members and form the consummate surveillance afterwards.

The physical realization of system

It is clear that the net equipment adopted by the system design all have the flexible expansion capacity, parts of the net equipment have the function of superposing which can provide convenience for the expansion and the upgrade of the network and the protection of the current investment of the customers. The whole net design consider the capability of expansion in two ways:

(1) the expansion of influx

Local area network (LAN) exchanging machine is equipped with the 100 exchange and 10/100M to self-adapting exchange to Ethernet module net. Attentions are paid to the design of utilization of fiber in floor backbone net. Each selected backbone net equipment is equipped with ATM module for the upgrade to the ATM network.Wide area net equipment supports various access and bandwidth (from 2400bps to 64k bps, the maximum 2M bps), adapt easily to the increase of thruput of LAN.

(2) the expansion of capacity

Observation of TCP/IP agreement to support various topological structure and immense capacity of the net scaleIn addition, the LAN of the exchange adopt the Ethernet to expand main frame and network equipment conveniently; the LAN equipment holds the interface for further expansion and superposing; the LAN of exchange is connected to the terminals of branches and members within the LAN through the route. And the route needs merely dynamic increase when the new branch or member joins in.
