# 逐仓保证金
逐仓保证金模型是一种在永续合约交易中使用的保证金管理方法，与全仓保证金模型形成对比。它具有以下主要特点：
* **独立保证金账户**
独立保证金账户在逐仓保证金模型中，每个合约头寸都有其独立的保证金账户。这意味着每个头寸都有自己的保证金池，并且不与其他头寸共享。这种独立性确保了一个头寸的损益不会影响其他头寸。
* **单独清算**
在逐仓保证金模型下，当一个头寸产生一定程度的损失时，只有该特定头寸被清算，而其他头寸保持不受影响。这有助于维护其他头寸的完整性，降低账户的整体风险。
* **杠杆控制**
逐仓保证金模型允许交易者更有效地控制每个头寸的杠杆。这有助于避免过度杠杆，因为每个头寸可以根据市场条件和风险承受能力单独管理。
Case Study
User A has 10,000 USDX in his Exchange Wallet. He uses 5,000 USDX as collateral to open a 20x leveraged short BTC perpetual position. However, due to the price volatility of BTC, User A's position gets liquidated. In this case, with the isolated margin model, User A only loses the 5,000 USDX used as position collateral. The 5,000 USDX in his wallet remains unaffected.
案例研究
用户A在其交易所钱包中有10,000 USDX。他使用5,000 USDX作为保证金，开设了一个20倍杠杆的BTC永续空头头寸。然而，由于BTC价格的波动性，用户A的头寸被清算。在这种情况下，使用逐仓保证金模型，用户A仅损失了作为头寸抵押品的5,000 USDX。他钱包中的另外5,000 USDX不受影响。
