NAME
Math::Business::EMA - Technical Analysis: Exponential Moving Average
SYNOPSIS
use Math::Business::EMA;
my $avg = new Math::Business::EMA;
$avg->set_days(7);
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_ema = new Math::Business::EMA(10);
