Any securities company supports five or less third-party depositories, but some brokers do not support a single bank. I took my ID card, shareholder card and bank card to the securities company to handle the tripartite depository agreement, and then I went to the bank to do tripartite depository.

In securities trading activities, the trading settlement funds of investors (that is, customers) are uniformly deposited by securities companies. Later, the CSRC stipulated that customers' transaction settlement funds should be uniformly deposited by third-party depository institutions. The third-party depository institutions here are commercial banks with third-party depository qualifications.

Precautions:

Client funds are closed. In this mode, the securities company will hand over the customer's fund access function to the depository bank, and the securities company will no longer handle any form of customer fund access business. All deposit and withdrawal behaviors are initiated by the customer through bank-securities transfer, and the transaction settlement funds withdrawn by the customer can only be returned to the bank settlement account with the same name specified in advance, so as to realize the closed operation of the transaction settlement funds and prevent the risk of misappropriation of customers' funds and withdrawal of customers' money laundering.

Total score check of depository bank. In this mode, the depository bank opens a management account for customers that maps the balance of the subsidiary ledger of their securities companies, so as to master the subsidiary ledger of customers and check it with the general ledger of securities companies, thus preventing the misappropriation of securities companies at the general ledger level to some extent.

The customer inquires about the reconciliation mechanism in another way. In this mode, the depository bank will provide customers with another way to inquire about the management account. With the help of inquiry means and reconciliation mechanism provided by depository banks and securities companies, customers can effectively monitor the safety of customers' funds by comparing the data consistency of their management accounts with those of securities companies.
