NAME

Math::SMA - SMA in object form

SYNOPSIS

    use Math::SMA;
        my $sma = Math::SMA->new(size => $n);
        $sma->sma($value);

DESCRIPTION

Implements a simple moving average of N periods with an amortized runtime complexity of < O(n²).

http://en.wikipedia.org/wiki/Moving_average

new

Create a new SMA object of $n periods.

        my $sma = Math::SMA->new(size => $n);

sma

Add a value to series and return the current simple moving average

    $sma->sma($current);

$current is the current live value

Returns last_avg if called with no arguments.

precision

The precision level for decimal places. Defaults to 2.

last_avg

The current value of the SMA series.

values

The current values of the SMA period. If you want to continue a series from a previous time, then pass an arrayref in during object construction:

        $sma = Math::SMA->new(size => 5, values => [3,2,7,4,9] );
