排名是当前读数在窗口内最低与最高读数之间的位置,所以过去只要有一个极端值,之后的读数都会被压在一端附近。百分位是低于当前读数的交易日所占的比例,不受那个极端值有多极端的影响。窗口内少于 180 个交易日时,两者都不显示。

虚线标出零的位置,即 25-delta put 与 call 隐含波动率相同之处。
03 · 偏斜

按 delta 排列的隐含波动率
本交易日没有任何到期日拟合出曲线
横轴是 call 的 delta。虚线中线右侧的读数取自该行权价上的虚值 put,波动率正是从这个合约的报价反解出来的。只有在保留下来的报价从两侧夹住该 delta 时才会画点;最后一个有成交的行权价之外一律不外推。
各到期日的两翼读数
本交易日没有任何到期日得出可用的曲面。
上面每条曲线代表一个到期日。纵向位置是隐含波动率,横向位置是读数所取合约的 delta。对美股来说,曲线通常向右上方倾斜,也就是虚值 put 的隐含波动率高于距离相同的 call。
25-delta 风险逆转把这个斜率概括成一个数字:25-delta put 的波动率减去 25-delta call 的波动率。蝶式价差(butterfly)概括的是弯曲程度:两翼的平均值减去平值读数。

横轴是距到期天数的平方根,这是波动率本身所在的尺度。按方差计算平坦的曲线,在这里会画成一条直线,而不会在最近一周急剧弯折。

插值是对总方差做线性插值,而不是对波动率。直接对波动率插值,隐含的两个到期日之间的远期方差可能为负。超出最长上市到期日的期限会标为不可用,而不是外推。
期限结构斜率
最近 284 个交易日
虚线标出 1.00,即 90 天与 30 天平值波动率相等之处。在它上方,较长期限的波动率更高。
期限结构就是每个上市到期日的平值隐含波动率,按到期日有多远排开画出来。标的平稳时,它通常缓缓向上倾斜,因为期限越长,能容纳的不确定性越多。
当市场为某个有确定日期的事件定价时,它会倒挂:包含预定公告的到期日,除了平常交易的方差之外还要加上该事件的方差,所以较短的合约可能显示出比较长合约更高的波动率。
