The latest version of our option pricing and analysis system. It calculates prices, risk parameters and implied volatilities using the Black- Scholes, Garman-Kolhagen and Cox-Rubinstein (binomial) models. Opti-Calc prices European and American style options on bonds, commodities, currencies, futures and stocks. It also calculates sensitivities, such asDelta, Gamma, Kappa (Vega), Rho and Theta. Opti-Calc enables the production of pricing matrices, risk eturn profiles and implied volatility analysis for either individual or portfolios of options. An example spreadsheet is supplied free which enables the user to price options and manage risk 'straight out of the box' without any programming or 'spreadsheet' work.
