 *

WebCab Options and Future implements the following functionality:

General Interest Derivatives Pricing Framework

General Pricing Framework offers the following predefined Models and Contracts:

• Contracts: Asian Option, Binary Option, Cap, Coupon Bond, Floor, Forward Start stock option, Lookback Option, Ladder Option, Vanilla Swap, Vanilla Stock Option, Zero Coupon Bond, Barrier Option, Parisian Option, Parasian Option, Forward and Future.
• Interest Rate Models: Constant Spot Rate, Constant (in time) Yield curve, One factor stochastic models (Vasicek, Black-Derman-Toty (BDT), Ho & Lee, Hull and White), Two factor stochastic models (Breman & Schwartz, Fong & Vasicek, Longstaff & Schwartz), Cox-Ingersoll-Ross Equilibrium model, Spot rate model with automatic yield (Ho & Lee, Hull & White), Heath-Jarrow-Morton forward rate model, Brace-Gatarek-Musiela (BGM) LIBOR market model.
• Price Models: Constant price model, General deterministic price model, Lognormal price model, Poisson price model.
• Volatility Models: Constant Volatility Models, General Deterministic Volatility model, Hull & White Stochastic model of the Variance, Hoston Stochastic Volatility model.

Once the contract and the price/interest/vol model combination has been set you able to run the Monte Carlo Princing Engine which allows:

• Evaluate Price: Evaluate price estimate accordance to number of iterations or maximum expected error
• Estimate Error: Evaluate the standard deviation of the price estimate, and the minimum/maximum expected price for a given confidence level.

Exotic Options Module

The Exotic Options module implements the following methods and procedures:

• Types of Options - Within this module we show explicitly how-to and offer practical advice on the valuation of Asian, American (single and multi-asset), Lookback, Bermuda, European (single and multi asset) and binary options using the Monty Carlo and Finite Difference techniques.
• Finite Difference Methods - powerful method for finding solutions of the Black-Scholes Equations.
• • Single Asset Options - We provide an explicit and fully implicit algorithms including a framework in which to measure stability issues under differing scenarios.
  • Crank-Nicholson - is a fast and stable method for evaluating single asset option contracts.
  • Multi-Asset - Implement a general multidimensional finite-difference algorithm.
  • American, Bermuda Options Modification - we apply the `Successive Over-relaxation' technique in order to value American and Bermuda options.
  • Asian and Lookback - examples of how strongly path dependent options can be evaluated using Finite Difference methods is given.
• Monte Carlo - can be effectively applied to value a large range of option contracts.
• • Flow implementation - including generation of normal variables and the simulation of the random walk and corresponding cash flows ensures that our implementation of this technique can be applied to value almost any option contract.
  • Options on many underlying assets - Generate correlation random variable using Cholesky factorization in order to value options contract of European type which depend on many underlying assets.
  • Control Structure - the user has full control over the number of simulations and/or the required precision.

Options Module

The Options module offers the following functionality:

• European and Binary Options - The (Analytic) Black-Scholes model is fully implemented for European and Binary Options on stocks, currencies and indexes.
• `The Greeks' - We offer methods for the evaluation of `the Greeks' (delta, gamma, rho, theta, vega) for European options on stocks, indexes and currencies according to the Black-Scholes model.
• Volatility Estimates - the volatility may to estimated directly from historical values or from one of the following models:
• • ARCH - Autoregressive Conditional Heteroscedasticity model.
  • EWMA - Exponentially Weighted Moving Average model.
  • GARCH(1,1) - Generalized Autoregressive Heteroscedasticity model.
• Implied Volatility - Calculates the implied volatility for dividend and non-dividend paying stocks from the Black-Scholes formulae.
• Payoff Functions - Pay off functions at expiry for European and Binary Options are implemented.
• Put - Call Parity relations
• • Put - call parity relations for European options on an asset with no yield or a continuous yield.
  • Put - call parity relations for Binary options on an asset with no yield.
  • Implied risk-free interest - the implied risk free interest rate is calculated when either the prices of put/call European or put/pull Binary option is known.
• Trading Strategies - the following pay-off functions for the following option trading strategies are implemented.
• • Spread Option Strategies - Bull Spreads, Bear Spreads and Butterfly Spreads.
  • Combination Option Strategies - Straddles and Strangles.

Futures Module

The Futures module implements the following methods and procedures:

• Pricing on investment and consumption assets - Pricing of futures contracts on stocks, bonds, indexes, currencies and commodities.
• • Futures on stocks, bonds, indexes - evaluation for assets with or without income, effective gearing.
  • Futures on commodities - cost of carry, utility yield.
• Hedging - Portfolio hedging using index futures, optimal hedge ratio.
• • Portfolio Hedging - delta hedge a portfolio using the beta coefficient.
  • Optimal Hedge Ratio - the optimal ratio of the size of the position taken in futures contracts and the size of the exposure.
• Future Account management - margin, daily P&L, total equity, excess margin.
• Interest calculations - return, compound interest, compounding periods conversion.

The Risk Management functionality included within this Component:

• Delta Limit Monitoring - For a portfolio (which may include Futures, Options, etc) the delta limit can be assigned and checked.
• Scenario Analysis - Allows for an asset or portfolio to be stressed and for the resulting behavior to be analyzed. We offer methods which stress the asset in any one or two of the underlying market variables.

Technology Aspects
This product also contains the following features:

• GUI Bundle - we bundle a suite of graphical user interface JavaBean components (with 1, 2, 4 or site-wide license) allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications
• EAR Files - we provide individual customized EAR files for the most widely used application servers including IBM WebSphere 4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Sun ONE AppServer 7, Ironflare Orion 1.5.2/1.6.0, Borland AppServer 5.0, Sybase EAServer 3.6 and JBoss 2.4.4/3.0.0
• Self-Deploy - the relevant servers EAR file will be self-deployed onto supported local application servers during the installation of the self-install package. The supported application servers include IBM WebSphere 4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Borland AppServer 5.0, Ironflare Orion 1.5.2/1.6.0 and JBoss 2.4.4/3.0.0
• JDBC Mediator - A server side EJB component which mediates between an EJB component, clients and DBMS. The mediator moves most of a clients JDBC calls to the server and hence greatly increases the speed of JDBC client applications.
• Web Application Example - A JSP interactive HTML interface which enables you to test every component method directly from your browser.
• Synthetic JDBC - we use a JSP component to perform EJB calculations on SQL database columns from a remote DBMS. We apply an EJB function to certain rows from the database and list the output in HTML format. This is a powerful feature since it allows you to perform calculations in a JDBC manner without having to code the EJB-to-JDBC transaction yourself as it is all done by the JSP within the Application Server.
• UML Models - to assist system architects we provide UML diagrams of this component
