Strike Price/Striking Price

In options, the pre-determined price at which the option may be exercised. For example, a gold call option is bought at a strike price of $300 for expiration in June. If the price is above $300 at the end of June, the buyer is entitled to buy gold at $300; that is to say, the option is in-the-money. If the price is below the $300 strike price, it is out-of-the-money and will not be exercised. Also known as the exercise price.
