I have three cards in Guotai Junan account, the main bank is ICBC, and the auxiliary banks are Chinese-funded in CCB (Guangdong) and ABC (Zhejiang) accounts.
At present, there is no charge for the transfer between securities and banks, including foreign bank cards. However, if there is no transaction between five transfers, the multi-line business will be suspended. On the same day, the funds transferred by the main and auxiliary banks can be traded in securities immediately. The money transferred from the Agricultural Bank of China on the same day should be transferred to ICBC or CCB and received the next day, but it was transferred back to the Agricultural Bank of China on the same day and received in real time.
