Implemented Financial InstrumentsBondsSupported calculations:

• Current Yield
• Holding Period Return
• Yield To Maturity
• Duration
• Modified Duration
• Convexity
• Price
• Clean price (v.2.4)
• Accrued interest (v.2.4)

A bond is a long-term contract under which a borrower agrees to make payments of interest and principal, on specific dates, to the holder of the bond. Bonds are classified into four main types: treasury, corporate, municipal and foreign depending on the issuing side. Each type differs with respect to expected return and degree of interest. When calculating the value of a bond, a discount rate is used which is the bond's market rate of interest. The discount rate is also called yield.FuturesSupported calculations:

• Price

• Currency
• Equity
• Commodity

The futures contract is an agreement between two parties to buy or sell an asset at a certain time in the future. The types of contracts are standardized in order the exchange trade of Futures contracts to be possible. The Futures asset is similar to the Forward asset type (the latter lacks standardization and is generally not traded on an exchange). Both are particularly simple derivatives. WSFA supports futures on currency, equity, and commodity.OptionsSupported calculations:

• Price
• Implied Volatility

• Currency
• Equity
• Futures

Options are one of the most complex financial instruments. The options are "derivative" financial instruments - they are always based on another asset.
Generally, the option represents the right but not the obligation to perform certain financial activity - it is upon the option holder to decide whether to execute the right or not.
WSFA supports the most widely used types of options - American and European. The underlying asset type supported are currency, equity, futures.
WSFA can also calculate the implied volatility of an asset. This means it can derive the volatility that the option-underlying asset should have, so that the price of the option is at some known level.
Implemented Business InstrumentsTime Value of MoneySupported calculations:

• Present Value
• Future Value
• Present Value of Annuity
• Future Value of Annuity
• Number of Payments
• Payment Amount

Financial decisions often involve situations in which someone pays money at one moment of time and receives money at some later time. Dollars that are paid or received at two different points of time are different and this difference is recognized and accounted for by the time value of money analysis. In fact it is true that, of all concepts used in finance, time value of money is the most important one. Cash FlowsSupported calculations:

• NVP, Net Present Value
• MIRR, Modified IRR
• Payback Period
• Discount Payback Period
• Equivalent Annuity

The cash flows calculations are the most frequently used method to analyze different investment opportunities. A given investment can be described by the different payments that will take place - negative amounts for the money You should invest and positive amounts for the future inflows from the investment.

Implemented Statistics InstrumentsStatisticsSupported calculations:

• Mean
• Standard deviation
• Coefficient of Variance
• Skewness
• Kurtosis
• Coefficient of Correlation
• Intercept (Linear regression)
• Slope (Linear regression

WSFA supports the most common statistical analysis calculations. To conduct these calculations, the user should enter a list of values for which he or she wants statistical information. Statistical analysis consists of single series analysis - computation of mean, standard deviation, etc. Some methods of finding statistical dependence between two series are also supported - coefficient of correlation and regression analysis.
