quote spread reading (triangles)
The curve view renders strike-level bid and ask implied volatilities as triangles:
- Up Triangle (▲): Implied volatility computed from the bid price.
- Down Triangle (▼): Implied volatility computed from the ask price.
- The vertical gap between the triangles shows the quoted bid-ask spread width directly around the theoretical curve.
reference markers
- White Vertical Line: Current spot price of the underlying asset.
- Gold Dashed Horizontal Line: 30-day average dealer ATM straddle implied volatility from the history service.
