Orc volatility models
WebWing Model是期权交易中常见的一种对波动率进行建模的方法。 它通过调整参数，将市场中一个系列的期权的隐含波动率拟合到一个曲线上。 Wing Model把隐含波动率曲线分为6个区域，以ATM Forward（期权对应标的远期价）为中心，左边区域1，2，3构成Put Wing，右边区域4，5，6构成Call Wing。 其中，区域1，6为常数波动率部分，区域3，4为抛物线部 … WebModels that try to parameterize the entire volatility surface are rare, but in an empirical investigation with DAX index options, the GARCH-based procedure performs considerably …
