Release Updates 11/06/07 - Fixed a bug on the OptionStrategies tab. The greeks for Stock positions were previously displaying 27/04/06 - Fixed a bug that failed to calculate the theoretical change in P&L for stocks in the strategies tab. 28/08/06 - Fixed a small calculation bug for the Option Theta, which now has a near perfect accuracy. 1/10/06 - Added support for Dividend Yield, which can be used as a workaround to price options on futures
by making the Dividend Yield the same as the Interest Rate.
Basic The worksheet labelled Basic is a simple option pricer. You simply enter the option details into the yellow shaded areas and the output values will be displayed underneath in the blue shaded cells.
OptionPage OptionPage is a worksheet that allows you to price a string of calls and puts for the same expiration date. Again, you enter the option details into the yellow cells and the output values are in the blue shaded cells. You can calculate the market implied volatility for each option by simply typing in the market price of the option in the column labelled "Market Price" and the volatility implied by the option's market value will show in the column "Implied Volatility". Column's A and L are where you can change the strike prices used for the calculations. Or you can just have the values derive straight from the Underlying Price by default.
OptionStrategies This worksheet lets you enter combinations of options positions so you can view the payoff/risk graphs. The underlying data for the options is taken from the information entered into the OptionPage worksheet. Then just enter the number of contracts for each position and remember to put a negative number for sell positions. For Type, just enter "c" for call options, "p" for put options and "s" for stock/futures position. If you know what the option is trading at, you can enter the market price in the "override premium" row to calculate the P&L of the position after taking into account the actual price of the option.
StrategyGraphs
This worksheet will show the current Greek position values of your option strategy while referencing the a range of underlying prices. You can change the range of values by changing the cell A17 in the OptionStrateg worksheet.
