[New regulations on transaction external access will be officially implemented today] On August 28, the China Securities Association and the China Securities Association jointly drafted the "Securities Company Trading Information System Access Management Specification (Trial)" and it will be implemented from the date of release. It aims to strengthen the access management of securities companies' trading information system and maintain the order of the securities market and market fairness. The "Specifications" clarify that securities firms shall carry out access to trading information systems in accordance with laws and regulations, prudently provide system access services, treat system access customers fairly, and shall not provide differentiated arrangements for technology or business resources for specific access customers. Consolidate the main responsibility of securities firms for the management of external system access, requiring securities firms to conduct full penetration management, comprehensively verify investor qualifications and complete verification of relevant system functions; effectively perform management responsibilities during the access process, strictly abide by the relevant regulations on existing transaction management in the securities market, strictly control risks, and ensure that system access always remains compliant, safe, and stable. After the release of the "Specifications", securities companies should establish and improve system access management systems and mechanisms as required, complete various functions of the trading system, strengthen system access behavior management, and effectively prevent business compliance and technical security risks. Qualified securities companies may submit a filing application to the Securities Association. External access to the trading information system refers to the behavior of securities companies that interact with investor trading order generation systems or functions by providing information system interfaces and other technical means to receive and process investor trading orders. With the development of the securities market, iterative updates of trading methods, and the rapid development of information technology, some professional investors have needs to use external trading to achieve warehouse management, unified risk control, and trading strategy execution. In order to standardize the external management of securities companies' transactions, the two associations conducted multiple rounds of visits and surveys to securities market entities, extensively listened to the opinions and suggestions of all relevant parties on strengthening the external management of securities companies' transactions, and formed the "Standard" based on summarizing the industry's practical experience and research results.
