1. 什么是維持保證金

維持保證金是指保持现有倉位所需的最低金額。在进行合約交易时，用戶賬戶中所需维持的最低保證金余額，当賬戶余額低于此水平时，用戶的倉位可能会被强制平倉。

2. 維持保證金的重要性

維持保證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倉者时，若賬戶保證金不足以維持倉位（即当前維持保證金率<=100%）时，强制平倉机制会触发，关闭部分或全部倉位以避免更大的损失。

3. 維持保證金的计算

用戶交易合約时需要的維持保證金采用梯度式算法，对于不同梯度的风险限額区间，我们设有不同的档位維持保證金率，风险限額区间越大，对应的档位維持保證金率越高。用戶的倉位价值、档位維持保證金率、手续费都会影响到最终維持保證金金額。

4. 如何管理維持保證金

为了避免强制平倉，用戶应定期监控賬戶保證金情况，并采取以下措施：

追加保證金：在賬戶保證金不足时，及时存入更多资金。
减倉：通过减少倉位来降低維持保證金要求。
使用止损单：设置止损价格，自动卖出以限制潜在亏损。
降低槓桿：降低槓桿倍数，增大容错率。

TruBit Pro 採取雙重風險機制，通過限制合約類型和結算賬戶的槓桿倍數，降低大額倉位被強制平倉的可能性。如果一些用戶的持倉數額非常大，理論上他們會給其他用戶帶來風險，這是因為，如果他們被強制平倉，其反方向的倉位可能會因自動減倉 (ADL) 機制而自動平倉。

雙重風險限額旨在通過限制槓桿倍數來避免這些情況。每當用戶下訂單時，TruBit Pro 系統將檢查相應合約類型和結算賬戶的風險限額，如果不滿足限額要求，則拒絕下單申請。
