smile.
Find the "greeks"  Delta, Gamma, Theta,
Vega, Rho. Dividend earnings as a percentage yield can also be included. European and American options
can be analyzed using the BlackScholes
option pricing formula, Binomial options pricing methods (CoxRossRubinstein),
Black method for futures or any of the other methods listed below.
1973 BlackScholes Option Pricing Formula
The BlackScholes Option Pricing Formula uses the following inputs:
 Strike price of the underlying stock
 Strike or exercise price
 Risk free interest rate
 Time in years until expiration
 Volatility of the underlying stock
Now, to compute the option prices and greeks, you could look up
issues such as how to compute the standard normal cumulative
distribution function and a set of equations to program. Or, we
suggest  simply try our wellproven options pricing software.
Here is an example of a simple options pricing calculator that was created using Options/NET:

Options/NET includes a number of popular models for estimating the theoretical option
prices and contains the following models:

BlackScholesMerton (allows for dividend yields)

Black (1976 Modification for Futures)

CoxRossRubinstein
(Binomial)

BjerksundStensland (fast estimation of American
options)

BaroneAdesiWhaley

GarmanKohlhagen (used to price European currency
options)

RollGeskeWhaley

French84 (allows for the effect of trading days)

Merton jump
diffusion

Historical volatility (estimate volatility using
raw price data)
These option pricing algorithms provide a method of
determining the call and put prices for European and American options, greeks, implied volatility
and volatility skew for both call and put options is also available.
Options/NET comes in 3 different editions:
Professional,
Enterprise and
Platinum.
The difference between each of these
methods is given in the table below:

If you are aiming to develop an option trading system for the stock market, try Options/NET, a .NET
DLL that enables you to quickly build your own system.
With the
addition of stock quotes, you can create your own option trading software,
customized to your own purposes. Options/NET includes sample
applications with source code in
Visual Basic .NET as a Windows application and as a Web application. You can quickly see just
how easy it is to price and analyse data using Options/NET.
Options/NET Control implements option pricing and analysis functions.
For each of the pricing models, the implied
volatility and volatility skew for both call and put options can be determined.

applications with source code in Visual Basic .Net.
You can quickly see just how easy it is to price and analyse options data using
Options/NET.
Options/NET is strong named, so it can be readily added to the GAC (Global
Assembly Cache).
Options/NET is written in C# with maximum speed and reliability and
can be used in a wide range of applications that support
the .NET standard. This includes Visual Basic .NET, Visual C# and more.
The trial version of Options/NET is feature limited: you will only be
able to access BlackScholes functions using the trial version. However it is
possible to develop trial applications to test out your ideas. If you need to
price American Options using the Binomial model (CoxRossRubenstein), or do
futures pricing, then by purchasing the full version you can obtain the full
capability.
The
BlackScholes option pricing formula can be used to compute the prices of Put
and Call options, based on the current stock price, the exercise price of the
stock at some future date, the riskfree interest rate, and the standard deviation of the log
of the stock price returns (the volatility).
A number of
assumptions are made when using the BlackScholes formula. These include: the stock
price has a lognormal distribution, there are no taxes,
transaction costs, short sales are permitted and trading is continuous and
frictionless, there is no arbitrage, the stock price dynamics are given by a geometric Brownian motion
and the interest rate is riskfree for all amounts borrowed or lent. It is possible to
take dividend rates for the security into consideration.
American options differ from European options by the fact that they can be exercised
prior to the expiry date. This means that the BlackScholes option pricing
formula is not suitable for this type of option. Instead, the
CoxRossRubinstein Binomial pricing algorithm is preferred. optionsnet implements
the binomial pricing algorithm for pricing American options. used to compute the prices of Put and Call options, based on
the current stock price, the exercise price of the stock at some future date,
the riskfree interest rate, the standard deviation of the log of the stock price returns (the
volatility), and if applicable, the dividend rate.
Given the option price, it is possible to find the volatility implied by that price. This is
known as the Implied Volatility and it has a number of characteristics which have
been used to identify trading opportunities. optionsnet implements implied volatility functionality for both American and European
options using the Binomial and BlackScholes methods respectively.
Implied volatility can be computed for both puts and calls across
a range of different strike prices. Interestingly, it is common for the implied volatility to vary
across this range. Plotting the implied volatility against the strike price results
in a curve that is termed the 'volatility smile'. This is due to the fact that it is common for
out of the money calls and puts to have higher implied volatilities. When there is a
difference between the implied volatilities using equal out of the money calls and puts, this is termed the 'volatility skew'.
Interpretation of the skew is the basis for some trading activities. If the ratio of Call volatility
to Put volatility is considered, a value greater than one may imply that the calls are priced higher
than puts with a resulting upward price bias and vice versa, ie. a call to put volatility ratio
less than one may imply that calls are priced lower
than puts with a resulting downward price bias. High skew ratios may indicate demand increasing for
puts, ie there are relatively more puts being bought and calls being sold, than puts being sold and calls being bought.
The analysis and interpretation of volatility skew should be undertaken with due care and diligence
and is a matter for skilled, professional traders.
