# 分段订单

分段订单是一种交易策略，它会在预设的价格区间内分批挂出多个买单或卖单，价格可以高于或低于当前市场价格。这会形成一系列较小的订单，使仓位逐步建立或逐步退出，而不是一次性执行大额订单。

***

### 何时使用？

* 当您希望在一个区间内 **平滑进场或出场价格**，而不是在单一价格点建仓或平仓时。
* 适合预期 **市场逐步波动** 的交易者，或希望降低波动性和滑点影响的人。
* 常用于在不确定的市场条件下 **逐步建仓**，或在获利时 **逐步减仓**。

***

### 关键点

* 通过在不同价格水平分散订单，有助于降低因择时不佳带来的风险。
* 可配置订单数量、价格区间及分布方式（平均分布或加权分布）。
* 执行依赖于市场波动 —— 如果价格未触及相关水平，部分或全部订单可能不会成交。
* 既适用于 **长期的逐步建仓策略**，也适用于 **波动市场中的短线交易**。

## 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/fen-duan-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.
