Forex options are exchange-traded derivative contracts that give the right but not the obligation to buy or sell a pair of underlying currencies at a pre-agreed price and date. Forex options are also known as currency options.
Every forex option can be split into a call or put option. A forex call option gives the holder the right to buy underlying forex pairs while a forex put option gives the holder the right to sell underlying currency pairs.
In either case, there is no obligation to exercise the contract but there is a pre-agreed price and expiration date attached. In India, forex options are only available for the USD-INR currency pair.
