Re: [GT] scan.pl error

["Todd Turner" <todd AT turnernet.org>]

I'm seeing the same behavior on revision 545 (mar 1).
display_indicator and display_signal both are working as expected.

Looking at the error message:

Argument "day" isn't numeric in numeric gt (>) at ../GT/Tools.pm line
453, <> line 1.
Can't call method "timeframe" on an undefined value at
../GT/Calculator.pm line 70, <> line 1.

Corresponds to the if statement in this codeblock:

foreach(reverse(@tf)) {
  next if ($_ > $timeframe);
  $q = $db->get_last_prices($code, $max_loaded_items, $_);
  last if ($q->count > 0);
}

When I print out $_ it is "CLOSE" and $timeframe is "day".  Not sure
if that is correct or not (I'm a GT and perl newbie so I might be
missing the obvious).  I'm using a EOD beancounter yahoo database.
