# 交易
## 在首页快捷买入
您可以在首页仅需2步快速完成代币的买入：
1. 在右上角设置好每次快捷买入操作的购买金额，单位为SOL；
2. 点击想要购买的代币列表最右端的购买按钮，在钱包中直接确认交易即可完成快捷买入操作。
## 在代币详情页面交易
任一代币的详情页面提供更加丰富的信息供您交易参考，我们建议您在进行任何一笔交易前遵从下列5步骤：
1. 仔细确认代币的Ticker，以确保您即将购买的是您想要购买的代币；
2. 明确交易方向，买入或卖出；
3. 填写交易金额，买入时您可以选择买入xx SOL或者买入 xx 代币；卖出时默认为卖出 xx代币；
4. 按需调整滑点上限和优先交易费；
5. 提交交易请求，并在钱包交易弹窗中二次确认交易详情，再批准交易。
\*Super Exchange上的所有交易均为链上交易，根据链上确认速度的快慢，最新的交易信息可能在几秒后才会刷新并出现在交易历史记录中。
## 设置交易参数
\*若无特别需求，您可以使用平台默认的交易参数进行交易，无需对交易参数作任何调整。
\
同时，Super Exchange也允许您按需调整两项交易参数以确保交易的执行符合您的预期，分别是滑点上限和优先交易费。
* 滑点上限\
滑点指的是交易报价与执行时实际价格之间的差额，这种差额经常因市场波动而变化。滑点设置较高时易被MEV机器人攻击；滑点设置较低时，若市场波动剧烈，可能会导致交易失败。交易热门代币时建议您适当提高滑点上线以确保交易成功；交易非热门代币时不要忘记把滑点调整到正常水平。
* 优先交易费\
在 Solana 上，每笔交易的基本费用为 0.000005 SOL。随着链上交易的增加，这些交易会争夺有限的空间。为了加快交易处理速度，您可以支付优先交易费，从而提高交易优先级，加快执行速度。

## 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.super.exchange/simplified-chinese/yong-hu-zhi-nan/jiao-yi.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.
