Mark pricing

Similar to our other Derivative products, a mark price will be calculated for options and used for margining purposes.

This mark price will be based on various factors and calculated using a SABR volatility model. Namely, the term structure of the underlying market, the IV curve available across multiple markets as well as other anti-manipulation factors.
