A futures account can only open the silver transfer service of 1 bank card at 1 bank. At present, there are 14 banks that can open bank-to-bank transfer in China, so a futures account can be associated with at most 14 bank accounts.

At present, there are ICBC, Agricultural Bank of China, Bank of China, China Construction Bank and Bank of Communications, as well as nine joint-stock commercial banks, namely Minsheng Bank, Industrial Bank, Shanghai Pudong Development Bank, China CITIC Bank, China Everbright Bank, China Merchants Bank, China Guangfa Bank, Ping An Bank and HSBC. Among them, the five major banks are connected by bank futures lines, and commercial banks generally use CICC first-line platform to connect. Although 14 banks have opened the function of bank-enterprise transfer, few futures companies have completed the docking with all banks, because every time they dock with a bank, futures companies have to pay a certain docking fee to the bank every year. The number of bank accounts docked by general futures companies is about 5 ~ 10, of which all five major banks are docked. Take the silver futures docking table of a domestic futures company as an example (the futures company where I currently work):

The following figure shows the schematic diagram of the connection between banks and futures special lines:

The following figure is a description of the CICC first-line docking platform:

Note: If you want to change the bank transfer business of the same bank, you need to cancel the bank transfer business of the original bank card before opening the bank transfer business of the new bank card.
