7, 30 and 90-day ATM implied volatility
- 7-day ATM IV
- 30-day ATM IV
- 90-day ATM IV
90d − 7d slope
vol points · backwardation below 0- 90d − 7d (vol points)
Each tenor interpolates total variance between that hour’s nearest listed expiries on either side. There is no extrapolation or gap filling. Positive slope means longer-dated IV is higher; backwardation is below zero. Missing observations break the chart lines. This is recorded venue data, not the whole options market or a trade recommendation.

A dash means listed expiries did not bracket that tenor or had no usable mark IV. Constant-maturity risk reversal history is unavailable because the historical summaries do not store separate 25-delta call and put IVs.
