public class Binomial : OptionValuation
The Binomial type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Binomial |
Constructor without parameters for accelerator usage.
|
| Binomial(OptionValuationModelOutputs, Int32) |
Constructor that defines which greeks should be saved for fast recomputation.
Note that at each query for any of saveable greeks all of them will be computed if needed.
|
| Binomial(OptionValuationModelInputs, OptionValuationModelOutputs, Int32) |
Enables advanced acceleration mode for specified option properties.
|
Properties| Name | Description | |
|---|---|---|
 | Charm | Charm, or delta decay, measures the instantaneous rate of change of delta over the passage of time. (Inherited from OptionValuation.) |
| Color | Color, or gamma decay, measures the rate of change of gamma over the passage of time. (Inherited from OptionValuation.) |
| Delta | Delta measures the rate of change of option value with respect to changes in the underlying asset's price. (Inherited from OptionValuation.) |
| Gamma | Gamma measures the rate of change in the delta with respect to changes in the underlying price. (Inherited from OptionValuation.) |
| OptionStyle | Option style. (Inherited from OptionValuation.) |
| OptionType | Type of option. (Inherited from OptionValuation.) |
| Rho | Rho, the derivative of the option value with respect to the risk free rate. (Inherited from OptionValuation.) |
| Speed | Speed measures the rate of change in Gamma with respect to changes in the underlying price. (Inherited from OptionValuation.) |
| Steps | Number of steps in binomial model. |
| StockPrice | Stock price of the underlying asset. (Inherited from OptionValuation.) |
| StrikePrice | Strike price of the underlying asset. (Inherited from OptionValuation.) |
| Theta | Theta measures the sensitivity of the value of the derivative to the passage of time: the "time decay". (Inherited from OptionValuation.) |
| TimeToMaturity | Time to the expiration date measured in years. (Inherited from OptionValuation.) |
| Value | Value of the option. (Inherited from OptionValuation.) |
| Vanna | Vanna, the second derivative of the option value with respect to the volatility. (Inherited from OptionValuation.) |
| Vega | Vega, the derivative of the option value with respect to the volatility of the underlying asset. (Inherited from OptionValuation.) |
| Volatility | Volatility of the underlying asset. (Inherited from OptionValuation.) |
| Zomma | Zomma measures the rate of change of gamma with respect to changes in volatility. (Inherited from OptionValuation.) |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetAnnualDividendYield | Get annual dividend yield. (Inherited from OptionValuation.) |
| GetDividends | Returns copy of actual underlying asset discrete dividends list. |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetRiskFreeRate | Get risk-free interest rate. (Inherited from OptionValuation.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
 | ImpliedVolatility(Double, Double, Double, Double, Double, OptionType, OptionStyle, Int32, Double) | Computes the underlying asset implied volatility. |
| ImpliedVolatility(Double, Double, Double, Dividend, Double, OptionType, OptionStyle, Int32, Double, Double) | Computes the underlying asset implied volatility. |
| InitByOptionPrice(Double, Double, Double, Dividend, Double, OptionType, OptionStyle, Int32, Double) | Initializes object by option parameters. |
| InitByOptionPrice(Double, Double, Double, Double, Double, OptionType, OptionStyle, Int32, Double) | Initializes object by option parameters. |
| InitByVolatility(Double, Double, Double, Dividend, Double, OptionType, OptionStyle, Int32, Double) | Initializes object by option parameters. |
| InitByVolatility(Double, Double, Double, Double, Double, OptionType, OptionStyle, Int32, Double) | Initializes object by option parameters. |
| OptionValue(Double, Double, Double, Dividend, Double, OptionType, OptionStyle, Int32, Double) | Computes option value for underlying asset price with dividends using Vellekoop method. |
| OptionValue(Double, Double, Double, Double, Double, OptionType, OptionStyle, Int32, Double) | Computes option value. |
| SetAccelerationGranularity | Sets acceleration granularity. Clears all computed values. (Inherited from OptionValuation.) |
| SetAnnualDividendYield |
Set annual dividend yield (e.g. value 0.02 means that yearly dividends income equals to 2 % of the underlying asset stock price).
All computed values are forgotten after this change.
(Inherited from OptionValuation.) |
| SetDividends | Sets new list of the underlying asset discrete dividends. Clears all computed values. |
| SetPrecision |
Option value for asset with volatility equal to ImpliedVolatility return
should be in [OptionValue∙(1 - precision), OptionValue∙(1 + precision)].
Default value is 1e-7.
Clears all computed values.
|
| SetRiskFreeRate |
Set risk-free interest rate (e.g. value 0.02 means that yearly risk-free income equals to 2 % of initial money amount
if there is no capitalization of interest).
All computed values are forgotten after this change.
(Inherited from OptionValuation.) |
