Global management consultancy Accenture said it had signed an agreement with the Shanghai Stock Exchange (SSE) to build a new electronic trading system targeted at the Chinese market. The new e-trading system will be based on the Deutsche Borse's Xetra trading system, the company said. Software development is expected to be completed within two years. The system will be the third to be used in Asia after those in Hong Kong and Malaysia. Accenture said the system would enhance the SSE's ability to offer additional products and services, and provide scalability for growing market demand.
