# 资金费率

Funding Rate，即资金费率，是永续合约中的重要机制。

它用于调节多空双方的持仓成本，使永续合约价格与现货市场价格保持相对接近。

***

### 为什么有 Funding Rate？

永续合约没有固定到期日。

为了让永续合约价格不过度偏离现货价格，市场通常使用资金费率机制。

***

### 谁支付 Funding？

资金费率可能由多方支付，也可能由空方支付，具体取决于市场情况和平台规则。

在 Jasper Vault，Funding 的具体计算和收取方式以平台展示为准。

***

### Funding 会影响什么？

Funding 会影响用户持仓成本。

如果用户长时间持仓，需要关注资金费率变化。

***

### 用户应如何看待 Funding？

用户应将 Funding 视为持仓成本的一部分。

在开仓前，用户需要同时考虑：

* 交易方向
* 杠杆
* 仓位大小
* 保护费用
* Funding 成本
* 可能的滑点
* 强平风险

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jaspervault.io/zhong-wen-wen-dang/he-yue-jiao-yi/zi-jin-fei-l.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
