The Black-Scholes formula is a widely used model for calculating the theoretical price of options. Chicago investment firm is offering a new financial derivative called a "windy put".The payoff formula is: Short call payoff per share = (premium per share - (MAX (0, (share price - strike price)). Options contracts allow investors to purchase the right, but not the obligation, to buy or sell an asset at a set price before the option expires.

Black–Scholes–Merton model is a mathematical model for the dynamics of a financial market containing derivative investment instruments.

It also discusses payoffs from long and short positions in call and put options. Here, as always, K is the strike price of the option.
