What is Option?

An option is a financial instrument that secures the right, though not the obligation, to buy or sell a given asset at a certain price on a specified date. The seller of an option is referred to as an option writer and the buyer of an option is referred to as option holder. In options trading to purchase an option on a given asset is to ‘Call’ and to sell is to ‘Put’.
