OptionPosition+ Version 4.1 OptionPosition+ is a financial analysis App that estimates the value of a set of shares and put and call options for a particular stock. It allows the investor to explore various option hedging positions and create a portfolio that is sensitive to price and volatility fluctuations or that provides protection for various concerns. OptionPosition+ graphically illustrates the value of put protection, covered calls, call spreads, time spreads, delta neutral skew trades, iron condors, etc.. Further information is available at https://www.optionposition.com OptionPosition+ comes with an initial one month subscription period that provides access to data on most stocks listed on the NYSE and NASDAQ and certain indexes (i.e. NDX, NQX, XND). After this one month subscription period you may purchase an auto-renewing subscription through an In-App Purchase. (If you do not maintain a subscription you can only access stock and option data for AAPL.) • Auto-renewable subscription • 1 month ($2.99), 2 month ($4.99) and 3 month ($5.99) durations • Your subscription will be charged to your iTunes account at confirmation of purchase and will automatically renew (at the duration selected) unless auto-renew is turned off at least 24 hours before the end of the current period. • Current subscription may not be cancelled during the active subscription period; however, you can manage your subscription and/or turn off auto-renewal by visiting your iTunes Account Settings after purchase. • Privacy policy and terms of use: https://sites.google.com/site/kramerkramersoftware/ OptionPosition+ Features: • delayed stock and option prices for all available strike dates and strike prices (delay varies from 0 to 20 minutes) • remembers 30 different portfolios each with 6 assets: ..........puts, calls, shares or child portfolios ......................child portfolios can have different underlying stock ......................child portfolios have correlated price ..........long, short any quantity ..........all listed strike dates ..........all listed strike prices ..........e-mail to anyone • Black-Scholes equation used to determine implied volatility and future value of put and call options • graphically displays Gain/Loss, Delta, Vega, Theta or Gamma as a function of stock price: ..........now (see black lines below) ..........at any future date up to the earliest strike date (see red lines below) ..........at assumed higher or lower volatilities (see green lines below) ..........with a changing price correlation to child portfolios included as an item/hedge • graphically displays the probability of future stock prices and the probability of future option portfolio Gains/Losses based on current put/call straddle prices • graphically displays the Volatility Smile for any expiration date • scales on the graph are continuously adjustable with one and two finger moves – easily zoom in or out • tap on the graph to show the X,Y value at a point and the value of the curves at that X value • diagnostics table shows all Greeks and lets you easily create a Delta neutral portfolio • 3 month US dollar LIBOR used for risk free interest rate • incorporates predicted dividend payments into the Black-Scholes calculations without making a ‘fixed dividend rate’ error in Delta Screen shots: For an explanation of these option positions, and more, see our website www.OptionPosition.com.

Simple and effective Black-Scholes solver to help you price different stock option chains. Allows you to calculate put / call option prices given volatility or solve for volatility given a put / call option price. In addition to the standard solver, this calculator lets you test the sensitivity of your answer to the different input variables. Quickly adjust any variable in the equation to see how it affects the final answer. Simply use the provided scroll bars once entering a value to adjust (on the fly) the final answer. Variables which allow for sensitivity study include: - Stock Price - Option Strike Price - Risk-Free Interest Rate In addition to solving the standard Black-Scholes formula, this calculator also adjusts the solution to account for dividends (if applicable) in the underlying stock. However, dividends can also be excluded from the calculation and set to zero if the user desires a true original Black-Scholes value. Standard inputs into the solver include: - Volatility - Call Price - Put Price - Current Stock Price - Date of Option Expiration - Stock Dividend Rate - Risk-Free Interest Rate Solutions from the solver include: - Volatility Given Put Price - Volatility Given Call Price - Put Price Given Volatility - Call Price Given Volatility Slight rounding errors in the final solution may exist due to the standard approximation made to solve the cumulative normal distribution function. However, the final value with these errors matches closely to many other Black-Scholes solvers available today.
