What the options market
is afraid of.
The implied volatility smile and its skew, strike by strike, and how both move when the fear changes side. In the app it is the Volatility page of the GEX workspace, on the option chain you load.

Questions
The same list feeds the page and its structured data.
Is the volatility suite included in the $29 plan?
Yes — IV smile, skew, term structure and the surface ship in the one plan, on the desktop app, alongside the footprint, heatmap and GEX. The first month includes everything.
Where does the implied volatility data come from?
From the option chain you load in the GEX workspace of the app — ThetaData, Tradier, Alpaca, Market Data or Databento with your key, CME options through Rithmic, or Deribit for BTC and ETH (personal use). Check the time stamp: delays can materially affect intraday interpretation.
Why would a futures trader care about options skew?
Because skew often moves before price. When put wings get bid on a quiet tape, someone is paying for protection they expect to need — that is context worth having before your next futures entry, no options account required.
Is the data on this page real?
No — every chart here runs on simulated data and says so on its badge. We never show numbers a visitor could mistake for real levels. The desktop app runs the same renderers on the chain you load.
It is in the one plan
No add-on, no tier.
