# 报价、滑点与价格源

Jasper Vault 的交易体验依赖报价、价格源和市场流动性。

用户在交易前应理解报价与滑点的基本概念。

***

### 什么是报价？

报价是用户在下单时看到的交易价格或预估交易价格。

报价可能受到市场价格、流动性、仓位规模和平台风控参数影响。

滑点是指用户最终成交价格与预期价格之间的差异。

在市场波动较大或交易规模较大时，滑点可能增加。

* 市场波动

## 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/bao-jia-hua-dian-yu-jia-ge-yuan.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.
