The syntax for movavg has changed. There is no longer support for the input arguments Lead and Lagonly a single windowSize is supported, and there is only one output argument ma.

If you want to compute the leading and lagging moving averages, you need to run movavg twice and adjust the windowSize. Load the file SimulatedStock.

Data for a financial series, specified as a column-oriented matrix, table, or timetable. Timetables and tables must contain variables with only a numeric type. Data Types: double table timetable. Type of moving average to compute, specified as a character vector or string with an associated value. Data Types: char string. Number of observations of the input series to include in moving average, specified as a scalar positive integer.

The observations include windowSize - 1 previous data points and the current data point. The windowSize argument applies only to moving averages whose type is 'simple''square-root''linear''square''exponential''triangular'or 'modified'. The length of weights N determines the size of the moving average window windowSize. The weights argument applies only to a 'custom' type of moving average. To compute moving average with custom weights, the weights w are first normalized such that they sum to one:.

The normalized weights W are then used to form the N -point weighted moving average y of the input Data x :. The initial moving average values within the window size are then adjusted according to the method specified in the name-value pair argument Initialpoints.

Optional Indicates how the moving average is calculated at initial points before there is enough data to fill the windowspecified as a character vector or string using one of the following values:. The Initialpoints argument applies to all type specifications except for the 'exponential' and 'modified' options.

The object uses either the sliding window method or the exponential weighting method to compute the moving average. In the sliding window method, a window of specified length is moved over the data, sample by sample, and the average is computed over the data in the window.

In the exponential weighting method, the object multiplies the data samples with a set of weighting factors. The average is computed by summing the weighted data. For more details on these methods, see Algorithms. MovingAverage returns a moving average object, movAvgusing the default properties. Unspecified properties have default values. Unless otherwise indicated, properties are nontunablewhich means you cannot change their values after calling the object.

Objects lock when you call them, and the release function unlocks them. If a property is tunableyou can change its value at any time. Averaging method, specified as 'Sliding window' or 'Exponential weighting'. For every sample the window moves by, the object computes the average over the data in the window.

The magnitude of the weighting factors decreases exponentially as the age of the data increases, never reaching zero. To compute the average, the algorithm sums the weighted data. In this mode, the average is computed using the current sample and all the past samples.

This property applies when you set Method to 'Sliding window'. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint Exponential weighting factor, specified as a positive real scalar in the range 0,1].

A forgetting factor of 0. A forgetting factor of 1. All the past samples are given an equal weight. Since this property is tunable, you can change its value even when the object is locked. This property applies when you set Method to 'Exponential weighting'.Sign in to comment. Sign in to answer this question. Unable to complete the action because of changes made to the page.

The exponential moving average is a weighted moving average, where timeperiod specifies the time period.

Signal Smoothing

Exponential moving averages reduce the lag by applying more weight to recent prices. For example, a period exponential moving average weights the most recent price by The triangular moving average double-smooths the data.

Then it calculates a second simple moving average on the first moving average with the same window size. The length of the weight vector determines the size of the window. If larger weight factors are used for more recent prices and smaller factors for previous prices, the trend is more responsive to recent changes. The modified moving average is similar to the simple moving average. Consider the argument numperiod to be the lag of the simple moving average.

The first modified moving average is calculated like a simple moving average. Subsequent values are calculated by adding the new price and subtracting the last average from the resulting sum. Load the financial time series object, dis for Disney stock and look at the weekly data for this time series. Financial time series object specified using a time series object created using fints.

Number of previous data points specified as a nonnegative integer. Lag indicates the window size or number of periods of the moving average. Set of observations specified as a vector or matrix.

Dimension to operate along, specified as a positive integer with a value of 1 or 2. Exponential moving average is a weighted moving average, where timeperiod is the time period of the exponential moving average. For example, a 10 period exponential moving average weights the most recent price by Length of time period specified as a nonnegative integer.

Triangular moving average is a double-smoothing of the data. Then a second simple moving average is calculated on the first moving average with the same window size. Number of periods considered specified as a nonnegative integer. A weighted moving average is calculated with a weight vector, weights. Weights for each element in the window specified as a vector of weights. Moving average calculation returned as a vector or matrix.

You get exaclty the same averages, I guess they tried to give emphasis to the fact that one is long run and the other is short run. Anyway, the movavg implements the weighted moving average linear and exponential :. Unable to complete the action because of changes made to the page.
