数据获取

通过 cn-stock-data skill 获取数据:

  • 期权数据: 不同到期月份的期权价格
  • 期货数据: 不同月份合约价格
  • 波动率数据: 各月份IV

分析工作流

Step 1: 价差分析

  • 期权日历价差 = 远月期权价格 - 近月期权价格
  • 期货跨期价差 = 远月期货 - 近月期货
  • 价差的历史分布与当前分位数
  • 价差的季节性模式

Step 2: 策略构建

  • 买入日历价差:买远月+卖近月(做多时间价值)
  • 卖出日历价差:卖远月+买近月(做空时间价值)
  • 对角价差:不同行权价+不同到期月
  • 条件选择:低IV环境买日历,高IV环境卖日历

Step 3: Greeks管理

  • Theta:近月Theta衰减快于远月(策略核心收益)
  • Vega:日历价差通常Vega为正(做多波动率)
  • Delta:保持Delta中性或小幅偏向
  • Gamma:近月到期前Gamma风险增大

Step 4: 到期管理

  • 近月到期前的展期决策
  • 展期时机:近月剩余价值<0.5%时展期
  • 展期成本:新近月的时间价值
  • A股特征:月度合约间隔,展期频率固定

Step 5: 输出报告
