语法
cmFutEuropeanOptionPricer(instrument, pricingDate, futPrice, discountCurve,
futPriceCurve, volSurf, [setting], [model], [method])
详情
对商品期货欧式期权进行定价。
参数
instrument INSTRUMENT 类型标量或向量,表示需要定价的商品期货欧式期权。
pricingDate DATE 类型标量或向量,表示定价日期。
futPrice DOUBLE 类型标量或向量, 表示标的期货的现价。
discountCurve MKTDATA 标量或向量,表示折现曲线(IrYieldCurve)。
futPriceCurve MKTDATA 标量或向量,表示期货价格曲线(AssetPriceCurve)。
volSurf MKTDATA 标量或向量,表示波动率曲面(VolatilitySurface),该曲面由
cmFutVolatilitySurfaceBuilder 构建。
setting 可选参数,字典(Dictionary<STRING,
BOOL>),用于指定是否计算希腊字母(Greeks)所代表的期权价格敏感性指标。可选值:
| 键 | 值 | 描述 |
|---|---|---|
| calcDelta | 布尔值,默认为 false | 是否计算 Delta,即期权价格相对于标的资产价格的敏感性。 |
| calcGamma | 布尔值,默认为 false | 是否计算 Gamma,即期权 Delta 相对于标的资产价格的敏感性。 |
| calcVega | 布尔值,默认为 false | 是否计算 Vega,即期权价格相对于标的资产波动率的敏感性。 |
| calcTheta | 布尔值,默认为 false | 是否计算 Theta,即期权价格相对于时间变化的敏感性。 |
| calcRho | 布尔值,默认为 false | 是否计算 Rho,即期权价格相对于无风险利率的敏感性。 |
model 可选参数,STRING 类型标量。默认且唯一支持的值为“Black76”,表示采用 Black76 模型进行定价。
method 可选参数,STRING 类型标量。默认且唯一支持的值为“ Analytic”,表示采用解析法。
返回值
- 若不指定 setting 参数,返回 DOUBLE 类型标量,表示期权的净现值,即期权的理论价格。
- 若指定 setting 参数,返回字典(Dictionary<STRING, DOUBLE>),包含期权的净现值以及希腊字母(Greeks)所代表的期权价格敏感性指标。有关敏感性指标的说明请参考 settings 参数说明。
