After the deployment of the detailed settlement data project of the CSDC Shenzhen Branch on March 25, 2013, the CSDC began to provide settlement participants on the market with all-around detailed settlement data services.
      Detailed settlement data refers to the trade-for-trade settlement data for trading and non-trading businesses at the securities account level. Based on each transaction record, the detailed settlement data for each transaction covers such information as the securities account, custody unit, settlement account, securities code, quantity to be settled, transaction amount, and tax and fee for each transaction.
      Before deployment of this project, the CSDC Shenzhen Branch can provide settlement participants with detailed settlement data at the securities account level only for a small number of innovation services, in addition to the detailed fund data at the settlement account level and the summary data at the custody unit level. When multiple products share a custody unit, it is time-consuming for settlement participants, including related securities companies and custody banks, to break down the summary data at the custody unit level into detailed data.
      In order to provide better and more comprehensive registration and settlement services for settlement participants, the CSDC Shenzhen Branch had initiated a development project on detailed settlement data, and made great efforts to extend the scope of the detailed settlement data service at the securities account level to cover the high-volume and diversified securities trading and non-trading businesses occurred every day. After deployment of this project, the detailed settlement data for trading businesses areincluded in the original settlement detail databases of SJSMX0 and SJSMX1. Where, data in SJSMX0 are sent in different batches on the trading day, and data in SJSMX1 are sent at about 16:00 on the trading day; the detailed settlement data for non-trading businesses are included in the original settlement detail databases of SJSMX2 and SJSJG, which are sent at about 17:30 on the trading day. Securities companies and custody banks can receive the aforesaid data directly through the D-COM, while non settlement participants such as fund management companies can also receive such data through the D-COM after they send a request for a copy of such data to the CSDC Shenzhen Branch via the electronic platform for the securities fund settlement business.
      Inheriting the original architecture, the detailed settlement data project sets up a multi-level data service structure, improves the data service system, and comprises the trade-for-trade detailed settlement data at the securities account level, the summary data at the custody unit level, and the detailed fund data at the settlement account level. In addition, based on an improved clearing system architecture, the project meets the planned target of processing 200 million transactions a day and lays a solid foundation for developing innovative services in Shenzhen and providing multi-level data services for settlement participants.
