NAME

Math::Business::WMA - Technical Analysis: Weighted Moving Average

SYNOPSIS

use Math::Business::WMA;

my $avg = new Math::Business::WMA;
   $avg->set_days(8);

my @closing_values = qw(
    3 4 4 5 6 5 6 5 5 5 5 
    6 6 6 6 7 7 7 8 8 8 8 
);

# choose one:
$avg->insert( @closing_values );
$avg->insert( $_ ) for @closing_values;

if( defined(my $q = $avg->query) ) {
    print "value: $q.\n";  

} else {
    print "value: n/a.\n";
}

For short, you can skip the set_days() by suppling the setting to new():

my $longer_avg = new Math::Business::WMA(10);
