# Degen Mode 动态费用
PancakeSwap 永续合约 Degen Mode 使用动态费用模型。此费用旨在根据 PnL 收取费用，并保护用户免受损失。\
**它是如何运作的？**
$$
\text{closeFeeRate} = \max\left(\frac{\text{pnl} \cdot \text{shareRate}}{\text{notional}}, \text{closeMinRate}\right)
$$
其中：
* Pnl 是仓位的盈亏
* shareRate 是分成率，即以费用形式支付的名义价值的百分比（默认为 15%）
* Notional 是用于开仓的资金金额
* closeMinRate 是最低平仓费用率，即你平仓所需支付的最低金额（默认为 0.03%）
\
**示例：**
如果你有一个盈利为 $100、分成率为 15%、名义价值为 $600 的仓位，那么平仓费用率为：
平仓费用率 = Max(100 \* 15% / 600, 0.03%) = 0.03%
在这种情况下，平仓费用率为 0.03%，即最低平仓费用率。
注意：
执行费用仅在开仓时收取。它设定为 0.3 USD（BNB Chain）/ 0.2 USD（Arbitrum）/ 0.01 USD（opBNB）/ 0.3 USD（Base），与交易经典永续合约交易对时收取的费用相似。没有开仓费用。
在清算事件中，90% 的流动性损失率包含平仓费用。

## 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.pancakeswap.finance/chinese/jiao-yi/perpetual-trading/perpetual-trading-v2/degen-mode/degen-mode-dynamic-fee.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.
