# MADBTCUSD

**1. 什么是 MADBTCUSD 指数？**

MADBTCUSD 指数是一个算法生成的价格指数，它涵盖了 BTC 的动态走势，但有一个额外的变化——它表现出显著更高的波动性。该指数采用几何布朗运动（GBM）衍生品定价方法推导得出，这是一种金融界常用于模拟资产不可预测性的数学模型。

**2. 它是如何运作的？**

MADBTCUSD 指数主要基于比特币的价格。它反映了 BTCUSD 的总体涨跌，但以放大的速率进行（预期波动率为 100%），从而产生一个价格波动显著更为明显的指数。为了保持透明和公平，MADBTC 价格可以通过 BTC 价格和 MADBTC 历史价格数据进行交叉验证（[此处](/chinese/jiao-yi/perpetual-trading/perpetual-trading-v2/madbtcusd/madbtcusd-faq.md)）。这确保了该指数准确反映标的 BTC 市场的走势。

将 MADBTCUSD 与传统加密货币区分开来的一个关键特点是随机性元素。MADBTCUSD 合约的价格是使用相应合约的数据和一个随机数的组合通过算法生成的。买卖双方对 MADBTCUSD 指数的价格没有影响。

**3. 市场可用性：**

目前，MADBTCUSD 指数在 BNB Chain 上的经典模式中可用，与 BTCUSD 和 ETHUSD 等其他主要市场并列。该合约提供额外的好处，例如零开仓费用、基于 PnL 的平仓费用以及高达 250x 的杠杆。

如果你对 MADBTCUSD 的概念感到好奇，并希望进一步探索此合约的细节，这里有一个专门的 [FAQ](/chinese/jiao-yi/perpetual-trading/perpetual-trading-v2/madbtcusd/madbtcusd-faq.md) 页面，为你提供全面的方法论。

***需要注意的是，由于其极端的波动性，MADBTCUSD 可能并不适合所有交易者，因此在参与之前，进行你自己的研究并充分了解所涉及的风险至关重要***

## 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/madbtcusd.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.
