Option Pricing using the Binomial Tree Model in C. Option Pricing using upt Binomial Tree Model in C By Ameriacn. Introduction I would like to pyt forth a simple class that calculates the present value of an American option binoimal the binomial tree model.

Background Calculation of a European option is typically performed using the closed form solution that Fischer Black and Myron Scholes developed in While the Black-Scholes formula is well-known as the equation that triggered huge growth in the options markets, what are perhaps less well-known are some of the alternative models for pricing options, particularly for American-style options.

Ina few gentlemen by the names of Cox, Ross, and Rubenstein came up with what is known as the binomial tree or binomial lattice method. This is the standard method used for calculating the value of an American option. Unlike the Black-Scholes model, the binomial tree model is not a closed form equation, but rather is a computationally intensive numerical method.

Because of put-call parity, the behavior that two products with the same syystem must have the same value, we can create pput synthetic option by valuing a replicating portfolio of assets that have the same payoff. The model uses a lattice made up of discrete time steps, and each node in the lattice represents a possible price at a particular discrete point in time. We start at the final time step maturity and work biinomial, valuing each node along the way until we reach the current time.

Pricing American Options For an American option, we calculate the value of each binomial node as the maximum of either the Strike minus the Exercise price or zero for a callor the maximum binomal the Exercise price minus the Strike or zero for a put. The reason we must calculate this payoff at every node is because the owner of the option has the 'option' to exercise at every discrete time step.

Implementing the Binomial Tree In this example, my approach was to be as clear as possible in the code. If I was to include this code in a large-scale pricing system, I would of course not include pricihg financial math functions such as present value or n factorial in the binomial tree class. But for the sake of expediency, pricing american put option binomial system small functions are included within the class.

An enumeration, EPutCall, is used to represent whether the option is a call or a put. The user of this binomual may either pass all kption arguments in the constructor, or if instance reuse is required, can set properties. The arguments required are the current AssetPriceStrikeTimeStepVolatilityEPutCallEOptionStyleRiskFreeRateand Stepswhich is the number of discrete time steps the user designates the binomial tree to contain.

The core pricjng of the binomial tree model is pricing american put option binomial system value of each node on the tree. You may have noticed that this code only supports options on assets that do not pay dividends. This is because my counter, jis being used to calculate the current step number by subtracting j from the number of total steps step - j. The payoff is always the greater of the intrinsic value or zero, as intrinsic value cannot be less than zero. In this case, amercian are pricing a put option where the current price of the asset isthe strike is set at 95, the time to maturity is 0.

OptionValue ; Finally, let's compare our results with the final result of astep Monte Carlo simulation. After all, we don't want to amsrican on a model that hasn't been thoroughly tested! Points of Interest In addition to the binomial tree, American options may be modeled using a trinomial tree. This model assumes an asset may move up, down, or remain flat.

Another model is the jump diffusion model where asset price changes are assumed to not only vary in direction but also in magnitude. These models are, of course, more complex than the simple binomial tree but are typically closer to real world option pricing.

I would like to put forth a simple class that calculates the present value of an American prucing using the binomial tree model.

Calculation of a European option is typically performed using the closed form solution that Fischer Black and Myron Scholes developed in For an American option, we calculate the value of each binomial node as the maximum of either the Strike minus the Exercise price or zero for a callor the maximum of the Exercise price minus the Strike or zero for a put. Implementing the Binomial Tree. In this example, my lut was to be as upt as possible in the code. To modify the code for dividend-paying assets, simply subtract the dividend from the risk free rate pricing american put option binomial system that:.

The binomial coefficient is a part of the formula used in calculating the value of an individual binomial node. While intuitively we think of calculating the nodes on a binomial tree backwards, you will notice that my for loop is counting up. For an American option, we must calculate the expected payoff at each node of the opton. To use our little C binomial tree class, we can binomlal pass all pricong arguments into the constructor and retrieve the OptionValue property.

Finally, let's compare our results with the final result of astep Monte Carlo simulation. In addition to the binomial tree, American options may be modeled using a trinomial tree.
