Account held on behalf of the company. Ensure that the gold account cannot be directly used for trading, but is just a custody account, similar to a safe storage room. Margin account refers to an account that an individual or institution needs to pay a certain amount to a securities company or futures company before participating in investment, securities or futures trading, and the company holds it on its behalf. Investors need to pay a certain amount of margin in the custody account to participate in the transaction. Generally speaking, the margin requirement is calculated according to the actual fluctuation and risk factors of securities or futures and a certain proportion of total capital. Protecting the gold account is a safe trading method, because it can effectively control risks. Even if there is a loss, the loss will be relatively small because the trader provides less principal.
