波动率套利/Vega交易助手

数据获取

通过 cn-stock-data skill 获取数据：

期权数据: 各合约价格与IV
标的行情: 实时价格与历史波动率
VIX类指标: 中国波指/iVIX

分析工作流

Step 1: 波动率定价判断

IV vs HV(历史波动率)：IV偏高→卖波动率
IV分位数：当前IV在历史中的位置
VRP(方差风险溢价) = IV² - RV²
波动率期限结构：近月vs远月IV关系

Step 2: 策略构建

做多波动率：买入Straddle/Strangle
做空波动率：卖出Straddle/Iron Condor
波动率价差：买近月卖远月(或反向)
偏斜交易：买低IV行权价卖高IV行权价

Step 3: Delta对冲

建仓时Delta中性：调整期权比例
动态对冲：标的价格变动时重新对冲
对冲频率：日度/实时，平衡成本与风险
Gamma scalping：利用Gamma正值赚取对冲收益

Step 4: 风险管理

最大亏损控制：设置止损线
Vega敞口限制：控制波动率风险暴露
到期风险：临近到期Gamma风险急剧增大
黑天鹅防护：保留少量OTM期权作为保险

Step 5: 输出报告

输出格式

formal 风格（研报级）

# 波动率套利策略报告

## 一、波动率评估
| 指标 | 数值 | 信号 |
|------|------|------|

## 二、策略方案
[具体期权组合、Greeks]

## 三、对冲计划
[Delta对冲方案、频率]

## 四、风险控制
[止损、最大亏损]

brief 风格（快速分析）

## 波动率套利速览
- IV 25% vs HV 20%，IV偏高
- 建议：卖出Straddle，收取权利金
- Delta对冲：日度调整
- 最大亏损控制在权利金的150%
