1. Gate order failed: the estimated total initial margin rate after placing the order is below 100%. Please adjust the order quantity. See Figure 1.
2. I attempted to transfer cryptocurrencies from the margin account to the unified account. Because some cryptocurrencies in the margin account do not currently support borrowing USDT, there is no need to keep them in the margin account; the borrowed USDT amount for some cryptocurrencies is 0. See Figure 2.
3. Transfer SOLS from the margin account SOLS_USDT to the unified account. See Figure 3.
4. Ultimately, the order still failed. Checking the unified account, the total initial margin rate = total margin balance / total initial margin. The current issue is caused by the total margin balance being too low. See Figure 4.
5. Finally, I had no choice but to deposit USDT. The total margin balance changed from 861.11 USD to 1560.38 USD. See Figure 5.
6. Placed the order again, and it succeeded. So, to some extent, the available USDT is a misleading prompt message and no longer holds substantive meaning. See Figure 6.
