Volatility surface

Raw SVI parameters from DeepBook Predict, evaluated across a strike grid. The smile that drives every signal.

DeepBook Predict prices every binary option from a single live SVI volatility surface. The chart below plots that surface for the selected oracle expiry: total variance w(k) and implied vol per log-strike k = ln(K/F). This is the pricing brain — every signal the bot fires starts here.

Pick a different expiry above to flip between the active oracles. Shorter expiries usually show steeper smiles.
The shape of the smile matters: a clear skew tilts the directional bias gate on the IV-RV strategy and Margin-Lever; a flat smile means neutral.
If the SVI parameters age past maxSviStalenessSec, the bot refuses to trade off that oracle (visible as filter_reason: svi_stale on Signals).
