Bank-to-bank transfer is a business relationship among futures investors, futures companies and banks. Handling secondary business can ensure the real-time transfer of customers' funds between their bank settlement accounts and futures margin accounts, which is more flexible. So, is silver transfer safe? Is there a hidden danger of capital security? Theoretically, bank transfer is safe, after all, there are banks as intermediaries to monitor funds. In terms of security, the business system uses a dedicated grid information security machine. As long as you don't disclose the relevant operation password, the system absolutely guarantees the security of your fund transfer. However, some card friends reported that when you open an account in a futures company, the contract contains the following contents: 1. After you deposit the funds in the local bank, you can transfer the bank card funds into the futures account through the operation of bank card → futures deposit in the trading system (no need to enter the bank password), and then you can conduct futures trading. 2. The futures company specially reminds you that this bank card is a special bank card for futures investment funds. Please take good care of your bank card and password, and try to take good care of the funds in your futures account. From the above, we can see two doubts: 1, when the futures company stipulates that the bank card funds can be transferred to the futures account, it is actually "no need to enter the bank password"; 2. Try to leave the funds in the futures account, which is suspected of misappropriating the customer's deposit.
