1.什么是维持保证金

维持保证金是指保持现有仓位所需的最低金额。在进行合约交易时，用户账户中所需维持的最低保证金余额，当账户余额低于此水平时，用户的仓位可能会被强制平仓。

2.维持保证金的重要性

维持保证金的设置旨在保护交易所和其他交易者免受可能的损失。当市场价格不利于持仓者时，若账户保证金不足以维持仓位（即当前维持保证金率<=100%）时，强制平仓机制会触发，关闭部分或全部仓位以避免更大的损失。

3.维持保证金的计算

用户交易合约时需要的维持保证金采用梯度式算法，对于不同梯度的风险限额区间，我们设有不同的档位维持保证金率，风险限额区间越大，对应的档位维持保证金率越高。用户的仓位价值、档位维持保证金率、手续费都会影响到最终维持保证金金额。

4.如何管理维持保证金

为了避免强制平仓，用户应定期监控账户保证金情况，并采取以下措施：

追加保证金：在账户保证金不足时，及时存入更多资金。
减仓：通过减少仓位来降低维持保证金要求。
使用止损单：设置止损价格，自动卖出以限制潜在亏损。
降低杠杆：降低杠杆倍数，增大容错率。

TruBit Pro 采取双重风险机制，通过限制合约类型和结算账户的杠杆倍数，降低大额仓位被强制平仓的可能性。如果一些用户的持仓数额非常大，理论上他们会给其他用户带来风险，这是因为，如果他们被强制平仓，其反方向的仓位可能会因自动减仓 (ADL) 机制而自动平仓。

双重风险限额旨在通过限制杠杆倍数来避免这些情况。每当用户下订单时，TruBit Pro 系统将检查相应合约类型和结算账户的风险限额，如果不满足限额要求，则拒绝下单申请。
