Moving average

`tsmovavg`

is not
recommended. Use `timetable`

instead. For more

## Syntax

## Description

`tsmovavg`

calculates the simple, exponential, triangular,
weighted, and modified moving average of a vector
or `fints`

object of data. For
information on working with financial time series
(`fints`

objects) data, see Working with Financial Time Series Objects.

returns the exponential weighted moving average
for financial time series object,
`output`

= tsmovavg(`tsobj`

,`'e'`

,`timeperiod`

)`tsobj`

. The exponential moving
average is a weighted moving average, where
`timeperiod`

specifies the time
period. Exponential moving averages reduce the lag
by applying more weight to recent prices. For
example, a 10-period exponential moving average
weights the most recent price by 18.18%.
```
Exponential Percentage = 2/(TIMEPER + 1)
or 2/(WINDOW_SIZE + 1)
```

.

returns the exponential weighted moving average
for a vector. The exponential moving average is a
weighted moving average, where

).

returns the triangular moving average for
financial time series object,
`output`

= tsmovavg(`tsobj`

,`'t'`

,`numperiod`

)`tsobj`

. The triangular moving
average double-smooths the data.
`tsmovavg`

calculates the first
simple moving average with window width of
`ceil(numperiod + 1)/2`

. Then it
calculates a second simple moving average on the
first moving average with the same window
size.

vector. The triangular moving average

returns the weighted moving average for the
financial time series object,
`output`

= tsmovavg(`tsobj`

,`'w'`

,`weights`

)`tsobj`

, by supplying weights
for each element in the moving window. 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.

)

returns the modified moving average for the
financial time series object,
`output`

= tsmovavg(`tsobj`

,`'m'`

,`numperiod`

)`tsobj`

. 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.
