Math::Business::EMA - Technical Analysis: Exponential Moving Average


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);

I normally hang out on #perl on freenode, so you can try to get immediate gratification there if you like. irc://irc.freenode.net/perl
