For an extensive review of the Bachelier model, see the review paper, A Black-Scholes User's Guide to the Bachelier Model [5], which summarizes the results on volatility conversion, risk management, stochastic volatility, and barrier options pricing to facilitate the model transition. The paper also connects the Black-Scholes and Bachelier ...
In the Black–Scholes model, the price of the option can be found by the formulas below. [27] In fact, the Black–Scholes formula for the price of a vanilla call option (or put option) can be interpreted by decomposing a call option into an asset-or-nothing call option minus a cash-or-nothing call option, and similarly for a put – the binary options are easier to analyze, and correspond to ...
The terms and are put in by-hand and represent factors that ensure the correct behaviour of the price of an exotic option near a barrier: as the knock-out barrier level of an option is gradually moved toward the spot level , the BSTV price of a knock-out option must be a monotonically decreasing function, converging to zero exactly at =. Since ...
In fact, the Black–Scholes formula for the price of a vanilla call option (or put option) can be interpreted by decomposing a call option into an asset-or-nothing call option minus a cash-or-nothing call option, and similarly for a put—the binary options are easier to analyze, and correspond to the two terms in the Black–Scholes formula.
whether the option holder has the right to buy (a call option) or the right to sell (a put option) the quantity and class of the underlying asset(s) (e.g., 100 shares of XYZ Co. B stock) the strike price, also known as the exercise price, which is the price at which the underlying transaction will occur upon exercise
At each final node of the tree—i.e. at expiration of the option—the option value is simply its intrinsic, or exercise, value: Max [ (S n − K), 0 ], for a call option Max [ (K − S n), 0 ], for a put option, Where K is the strike price and is the spot price of the underlying asset at the n th period.

The Black model (sometimes known as the Black-76 model) is a variant of the Black–Scholes option pricing model. Its primary applications are for pricing options on future contracts, bond options, interest rate cap and floors, and swaptions. It was first presented in a paper written by Fischer Black in 1976.
