# 什么是永续合约保护（PP）

永续合约保护（PP）是 Jasper Vault 的核心保护功能。

它允许用户在进行永续合约交易时，为仓位附加一层期权式保护，从而在继续持仓的同时，更清楚地管理部分下行风险。

简单来说：

**永续合约保护（PP）是合约仓位的保护层。**

***

### 永续合约保护（PP）解决什么问题？

在普通合约交易中，用户常常面临两难选择：

#### 选择止损

止损可以帮助用户控制风险。\
但一旦价格触发止损，仓位通常会被直接平掉。

如果价格只是短暂插针，随后又快速反弹，用户可能已经失去仓位。

#### 选择继续持仓

继续持仓可以保留后续行情机会。\
但如果行情继续不利，仓位可能进一步亏损，甚至接近强平。

永续合约保护（PP）希望提供第三种选择：

**用户可以继续持仓，同时为仓位增加保护。**

***

### 永续合约保护（PP）适合哪些用户？

它适合：

* 想继续持仓，但担心短期剧烈波动的用户
* 不想被普通止损轻易扫掉的用户
* 夜间或外出时无法盯盘的用户
* 仓位已有浮亏，但仍希望观察行情的用户
* 愿意为风险保护支付一定成本的用户

***

### 一句话理解永续合约保护（PP）

**永续合约保护（PP）不是帮你预测市场，而是在你决定继续持仓时，为仓位增加一层保护。**
