# 市场评级（第 3 层）
这是 Steakhouse Financial 的多层风险评级中的第 3 层。市场评级评估资本部署所在的具体借贷或投资场所，并从四个标准进行衡量：预言机、流动性、价格波动和 LLTV。后两项结合形成信用增强。
市场是一个 DeFi 协议，它使拥有闲置资本的投资者能够通过与其交互来获得收益，同时将该资产作为抵押品（在有抵押贷款中）或更广泛地作为主要风险来源。
每个市场都由协议参与者设立，并由利率曲线、基于预言机的定价方法以及 LLTV 等参数定义。通过受限的设置可以缓解市场波动，因此有必要同时评估其稳健性以及作为投资头寸的适用性。
市场依据四个标准进行评估：预言机、流动性、价格波动和 LLTV，其中后两项构成信用增强，这是一个会调整资产评级的额外层级。

## 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://steakhouse.financial/docs/risk-management/zh/collateral/layers-pillars-and-criteria/market-rating-layer-3.md?ask=&goal=
```
`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.
