IV: |
Current daily level of *Implied Volatility (IV)* for options on this
futures contract, as derived from (implied by) options premiums (Black Model). A green
number highlights IV above +1 Standard Deviation (STD); a red
number highlights IV below -1 STD. Historical volatility has theoretically been found to be
between +1 and -1 STD 67% of the time. |

HV: |
Current daily level of 20-day *Historical Volatility (HV)* for this
futures contract, as calculated from futures price movement. A green
number highlights HV above +1 Standard Deviation (STD); a red
number highlights HV below -1 STD. Historical volatility has theoretically been found to be
between +1 and -1 STD 67% of the time. |

CTHV: |
Current daily level of the *Central Tendency of Historical Volatility (CTHV)*,
the 15-year average of 20-day historical volatility (of futures prices). Thus, CTHV is the
historical reference against which to compare IV and HV. CTHV is also used to calculate +1 and -1
STD (Standard Deviation), between which HV has theoretically been found 67% of the time. Thus,
an IV or HV above +1 STD (green number) or below -1 STD (red
number) is considered outside the historical norm. |

D2Ex: |
Conveniently enumerates how many days until options on that futures contract expire. |
