Options trading involves buying and selling rights and obligations through derivative contracts called options. There are four types of options contracts: calls, which give the buyer the right to buy the underlying asset at a set price; puts, which give the buyer the right to sell the underlying asset; and writing calls and puts, which obligates the writer to buy or sell the underlying asset if assigned. Unlike traditional trading, options have an expiration date, so traders must consider time value and volatility, both of which impact the pricing of options.
