Currency Translated options
Currency translated options are options on foreign assets where the payoff is exchanged into domestic currency at expiration. For example, a U.S. investor is interested in buying an option that is linked to the Nikkei index that is priced in yen. There are two types or risks, changing prices and exchange rates, to consider when valuing currencytranslated options.
Currency Translated functions:
Equity Linked Foreign Exchange 
An equitylinked foreignexchange option is an option on the foreign exchange rate and is linked to the forward price of a stock or equity index. This option can be priced analytically using a model introduced by Reiner (1992). The FinOptions function EquityLinkedFX can be used to evaluate European equitylinked foreignexchange options. 


Foreign Equity 
A foreign equity option is an option on a foreign asset where the strike price is specified in either domestic or foreign currency and the payoff at expiration is valued in domestic currency. Foreign equity options can be priced analytically using a model introduced by Reiner (1992). The FinOptions function Foreign Equity can be used to evaluate European foreign equity options. 


Quanto 
A fixed exchangerate foreignequity option (Quanto) is denominated in another currency than that of the underlying equity exposure. The face value of the currency protection expands or contracts to cover changes in the foreign currency value of the underlying asset [1]. Quanto options can be priced analytically using a model published by Dravid, Richardson, and Sun (1993). The FinOptions function Quanto can be used to evaluate European Quanto options. 


Takeover Foreign Exchange 
A takeover foreign exchange call option gives the buyer the right purchase a specified number of units of foreign currency at a strike price if the corporate takeover is successful. This option can be priced analytically using a model introduced by Schnabel and Wei (1994). The FinOptions function TakeoverFX can be used to evaluate European takeover foreign exchange call options.
