in reply to Finance::Quote returns nothing and no error

Hello bulrush,

By making some changes to your code I was able to get this result (running from the command line under Windows 8.1):

23:25 >perl 1001_SoPW.pl
Price of GOOGL is 597.78 for 09/05/2014

23:25 >

[download]

Here is my revised script:

use strict;
use warnings;
use Finance::Quote;

getquote('googl', '20140822');

sub getquote
{
    my ($sym, $qdate) = @_;
        $sym          = uc($sym);
    my  $quote        = Finance::Quote->new;
    my  @exchanges    = sort($quote->sources);

    $quote->timeout(60);
    $quote->require_labels(qw/price date high low volume/);
    $quote->set_currency('USD');

    my $exch = 'usa';
    my %info = $quote->fetch($exch, $sym, 'A', 'MSFT');

    if (!%info)
    {
        my $s = "getquote ERROR: No information returned for symbol $s
+ym from $exch";
        warn $s;
        return;
    }

    my $dt = $info{$sym, 'date'};
    print "Price of $sym is " . $info{$sym, 'price'} . ' for ' . $dt .
+ "\n"; # DEBUG
}

The major change is to the line:

$quote->require_labels(qw/success errormsg price date exchange name/);

[download]

which I replaced with this line:

$quote->require_labels(qw/price date high low volume/);

[download]

copied from the “SYNOPSIS” section of the module’s documentation. I conclude that the module works, you just need to tweak the label settings.

BTW: Please note that Perl variables are best declared at the point of first use. Also, the second parameter to sub getquote is unused.

Hope that helps,

    Here is the code (same as yours) 
    use strict;
use warnings;
use Finance::Quote;

getquote('googl', '20140822');
my $s;
sub getquote
{
    my ($sym, $qdate) = @_;
        $sym          = uc($sym);
    my  $quote        = Finance::Quote->new;
    my  @exchanges    = sort($quote->sources);

    $quote->timeout(60);
    $quote->require_labels(qw/price date high low volume/);
    $quote->set_currency('USD');

    my $exch = 'usa';
    my %info = $quote->fetch($exch, $sym, 'A', 'MSFT');

    if (!%info)
    {
        $s = "getquote ERROR: No information returned for symbol $sym 
+from $exch";
        warn $s;
        return;
    }

    my $dt = $info{$sym, 'date'};
    print "Price of $sym is " . $info{$sym, 'price'} . ' for ' . $dt .
+ "\n"; # DEBUG
}

      Looks like the API was terminated last year. Also see Finance::YahooQuote which now says

      NOTE: As of November 2017, the module is no longer all that useful as Yahoo! decided to halt the API service it relies on.

      Some info is available using yahoo_json if you have a recent version of Finance::Quote

      use strict;
use warnings;
use Finance::Quote;
use Data::Dumper;

printf "Version : %s\n", $Finance::Quote::VERSION;

my $q = Finance::Quote->new();
$q->timeout(60);
$q->set_currency("USD");

my $stock = 'googl';
my $info = $q->fetch("yahoo_json",$stock);
print Dumper $info;
printf "Latest price for %s is %s", $info->{$stock,'name'},$info->{$st
+ock,'last'};
