各个币种根据流动性分为不同等级，借贷限额各有不同。负债越多，可用的杠杆上限越低，相应的维持保证金率与最低初始保证金比率就越高。

全仓杠杆专业模式保证金水平=∑净权益/∑维持保证金。如需了解详情，请参阅常见问题答疑。

Example:
The user borrowed 13 BTC and 13 ETH. Suppose that BTC price = 30,000 USDT and ETH = 3,000 USDT, then the required Initial Margin and Maintenance Margin are calculated as follows:
• USDT value of BTC Liability = 13 * 30,000 = 390,000, which falls in Tier 3. USDT value of ETH Liability = 13 * 3,000 = 39,000, which falls in Tier 2.
• Required ∑Initial Margin =∑Initial Margin required by BTC liability + ∑Initial Margin required by ETH liability= 50,000*11.12%+(100,000-50,000)*14.29%+(390,000-100,000)*20%+ 30,000*11.12%+(39,000-30,000)*14.29% = 75,327.1 USDT
• Required Maintenance Margin = ∑Maintenance Margin required by BTC liability + ∑Maintenance Margin required by ETH liability = 50,000*5%+(100,000-50,000)*7%+(390,000-100,000)*8%+ 30,000*5%+(39,000-30,000)*7% = 31,330 USDT
• Required Maintenance Margin can also be calculated in a faster way by using the Maintenance Amount. Liability token Maintenance Margin = Token Liability in USDT* Maintenance Margin Rate - Maintenance Amount. So the Required Maintenance Margin = ∑Maintenance Margin required by BTC liability + ∑Maintenance Margin required by ETH liability= (390,000*8% - 2,000) + (39,000*7% - 600) = 31,330 USDT
