Parameters

formulaName

A FinancialFormula enumeration value that determines the technical analysis or time series formula to be used.

inputSeries

A string expression consisting of one or more series with optional data point values. Multiple "series:values" should be comma-separated (e.g. "Series1:Y,Series2:Y3"). If a Y-value is not specified the first value (Y) is used.

This example demonstrates how to use the EaseOfMovement financial formula.  We assume that Series1 is populated with stock data (High, Low, Open and Close values). Series1 is also used to store the indicators in its first Y-values.

This method applies a formula to Y-values of one or more series' data points, and the input series are used to store the resulting data. The first listed input value is used to store the first output value, the second input value is used to store the second output value, and so on. If the number of input values is less than the number of output values an exception will be thrown.

Each particular formula has certain requirements, which are listed in the formula topics located in the "Formula Reference" folder.

This particular function definition cannot be used for those formulas that must have a parameter argument specified (use another definition that takes a parameters argument).

To apply a formula and preserve the input series use another definition of this function that uses an output series parameter (outputSeries).

Note: If you are applying an averaging formula (e.g. Simple Moving Average) see the StartFromFirst property.

For an overview of how to apply a formula see the Using Financial Formulas  topic. For a detailed discussion on a particular formula see that formula's topic in the "Formula Reference" folder.
