# 条件订单

**条件单 (Conditional Order)** 是一种买卖指令，当满足特定市场条件（例如达到某个触发价格）时触发。一旦触发条件被满足，订单会自动作为市价单或限价单提交。

***

#### 何时使用？

* 当你希望根据价格走势 **自动化进场或出场** 时。
* 用于 **防止亏损**（例如止损单 stop-loss）或 **锁定盈利**（例如止盈单 take-profit）。
* 当你无法持续监控市场，但希望在关键价位自动下单时。

***

#### 关键点 

* 通过结合触发条件和订单执行方式，提供了灵活性。
* 可以在条件满足后设置为 **市价止损单 (stop-market)** 或 **限价止损单 (stop-limit)**。
* 如果市场没有达到触发价格，或在设定限价价位没有足够的流动性，则不能保证执行。
* 常用于 **风险管理** 和 **战略性交易自动化**。

## 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://support.backpack.exchange/support-docs/cn/jiao-yi-suo/jiao-yi/ding-dan-lei-xing/tiao-jian-ding-dan.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.
