# 为主账户设置或修改费用方案
如果您在创建主账户时跳过了费用方案设置，可以在账户创建完成后设置费用方案。您也可以修改现有的费用方案。
{% hint style="info" %}
对现有费用方案所做的更改不会影响已有的跟单订阅。对于已有的跟单订阅，创建订阅时接受的费用方案仍然有效。修改后的费用方案仅适用于新的跟单订阅。
{% endhint %}
为主账户设置或修改费用方案：
{% stepper %}
{% step %}
在主菜单中展开相应的服务项目，例如 **LTI Copy Trading**、**MAM** 或 **PAMM**。如果该服务支持多个交易平台，请在所需平台下点击**我的账户（My Accounts）**。
{% endstep %}
{% step %}
在账户列表中点击相应的主账户。
{% endstep %}
{% step %}
在账户详情中，前往 设置（Settings）页面。
{% endstep %}
{% step %}
在**费用方案（Fee plan）部分，点击更改费用方案（Change fee plan）**。
Change a fee plan
{% endstep %}
{% step %}
输入您希望添加到费用方案中的各项费率，并选择费用支付周期。
费用方案中列出的费用将从已订阅该主账户的投资账户中扣除。
费率可以使用小数表示。请使用英文句点 `.` 作为小数点分隔符。
有关费用方案中可以包含的费用类型，请参阅**费用列表**。
{% endstep %}
{% step %}
点击 保存（Save）以应用更改。
{% endstep %}
{% endstepper %}

## 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://lti.gitbook.io/user_guide/zh-cn/yong-hu-zhi-nan/guan-li-zhu-zhang-hu-he-tou-zi-zhang-hu/wei-zhu-zhang-hu-she-zhi-huo-xiu-gai-fei-yong-fang-an.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.
