Hello,

I was under the impression that the first two bytes where the record length, but this does not appear to be the case with FIELD Descriptions    ID=DE (ASCII)

Please take a look at the following example where I request the historical data for DELL.  The length of the record type DE is set to '105', but this is obviously way longer than it is.

My perl script is below, and the output is in this file:
http://rapidshare.com/files/331889399/output.bin

Thanks,
Brian

use IO::Socket::INET;

sub OpenSocket
{
my $port = 16240;
$socket = IO::Socket::INET->new('PeerAddr' => $ARGV[0],
'PeerPort' => $port,
'Proto' => 'tcp')
or die "Can't create socket ($!)\n";
}

sub Send
{
        my $data = $_[0];
#       my $terminator=pack("h2", "FF");
    my $terminator=chr(255);
        print $socket $data;
        print $socket $terminator;
}

OpenSocket();

Also problem number two...

I don't understand the timeframes when requesting historical data.  I am requesting tick data but these are the timeframes I get.  They are not even evenly spaced, but follow a pattern...  Why is that?Huh?
