Math::Business::Stochastic - Perl extension for calculate stochastic oscillator

SYNOPSIS

  use Math::Business::Stochastic;

  my $stoc = new Math::Business::Stochastic;

  my ($k, $d, $sd) = (5, 3, 3);

  set_days $stoc $k, $d, $sd;

  my @high_values = qw(
      3 5 5 6 6 5 7 5 8 5 7
      8 6 8 6 8 7 8 8 9 8 9
  );
  my @low_values = qw(
      2 4 3 5 3 5 3 4 5 3 4
      4 5 6 6 6 6 6 7 7 6 7
  );
  my @close_values = qw(
      3 4 4 5 6 5 6 5 5 5 5
      6 6 6 6 7 7 7 8 8 8 8
  );

  for(my $i=0 ; $i<int(@close_values) ; $i++) {

      if( defined $stoc->query_k ) {
          print "Stochastic k:  ", $stoc->query_k,  "\n";
      }
      else {
          print "Stochastic k:  n/a\n";
      }
      if( defined $stoc->query_d ) {

  # you may use this to kick start
