A High Performance Quotes System for Bulk Commodities Exchange Market

One of the important design goals of electronic quotation system is to carry out high-speed data transmission while controlling the consumption of server-side computation resources and network bandwidth resources. Different from other exchange markets (e.g. stock market), bulk-commodity exchange market is characterized by fewer varieties of future contracts and more focus on single future contract. As inadequate attention has been paid to the market characteristics during the design stage for most existing bulk quotation systems, these systems are faced with such problems as huge uneconomic resource consumption and significant data transmission delay, and the design goals are difficult to realize. As novel quotation system architecture, HSQuotes employs separated channel, broadcast long-connection model and compressed HTTP short-connection model as well as other technologies to perform classified data storage and high-speed transmission. HSQuotes has been successfully applied to dozens of bulk-commodity exchange markets including steel, chemical industry, port trade and stock index futures, etc., and exhibits the characteristics of reliability, stability and high efficiency.
