Schema: SpdrTheoExpSurface (ID: 1960)

SpdrTheoExpSurface records reprent a client theoretical volatility surface for a ExpiryKey (ticker + expiration). These records can either directly specify parameters to be used in a parameterized surface function or can link to a record (eg. SpdrTheoExp2PtCurve) containing x/y points sampling a client constructed curve. Alternatively, they can specify that a SpiderRock implied skew curve should be used along with client supplied atm volatilities.

Surface dynamics can be specified in multiple ways with these records and a number of pricing parameter overrides are also available.

See the technical note on client supplied theoretical surfaces for more details.
