incorporate continuous compounded dividend yield for Equity options,
cost and convenience yield for Commodity options and
local and foreign risk-free rate in case of FX options.
It also allows option to give discrete dividends in cased of Equity options.

There is option to provide discrete dividends for Equity options for both the models.
- Implied volatility calculation under BSM framework model.
