A foreign currency option is essentially a contract in which the buyer buys the right to exercise the contract on or before the date of the contract.
The holder of the contract is called the buyer and the seller of the option is called the seller.
A call option is an option given in a foreign currency and the buyer of the contract is the buyer of the contract.
Therefore, we also call it a long option, a long option, or a knock-in option.
Call options give the buyer of term rights the right, but not the obligation, to buy a commodity at a strike price on or before a date in the future.
