A: At this time I am not going to implement any further features because I am not using Finance::Streamer for my own applications. If anyone implements new features I welcome their inclusion into Finance::Streamer and I will give credit where credit is due. ---------------------------------------------------------------------------- Q: What data provider do you recommend. A: I recommend using MyTrack [http://www.mytrack.com] for financial data because they provide an interface and documentation for using their data. Their interface has more features than most in that broker operations (buy, sell, etc) are also part of the interface. It is also very cost effective starting at just $25 per/month for delayed data. Note, they do not provided a Perl interface. A Perl interface to their C interface is possible but I found it very difficult to do using either Swig or Inline Perl. But if you need an interface for C/C++ or Java, MyTrack may suit your needs better than Finance::Streamer could. ---------------------------------------------------------------------------- Q: What tools did you use to reverse engineer the protocol? A: It has been a long time since I did this sort of work so there may be better tools available but the main things I used are the following: * tcpdump [http://www.tcpdump.org] * Richard Stevens. UNIX Network Programming * Richard Stevens. TCP/IP Illustrated Then it is just a matter of "sniffing" the packets and trying to decipher what is going on. My setup was a Linux machine connected to the Internet and acting as a router to a Windows machine on the internal network. Then I would start the sniffer (tcpdump), and then start the official streamer program on the Windows machine. Then I would try to figure out what is going on and then write code that does exactly what the official streamer application does. ---------------------------------------------------------------------------- Finance-Streamer-1.10/lib/0040755000175500001440000000000007734204570014215 5ustar jeriusersFinance-Streamer-1.10/lib/Finance/0040755000175500001440000000000007734204570015560 5ustar jeriusersFinance-Streamer-1.10/lib/Finance/Streamer.pm0100644000175500001440000004741707734204273017712 0ustar jeriusers# # If you don't know what the '{{{' '}}}' are for, they are used # for folds in the vim text editor (:help fold). # # {{{ Intro =head1 NAME Finance::Streamer - Interface to Datek Streamer. =head1 VERSION This document refers to version 1.07 of Finance::Streamer, released Tue, 27 Aug 2002. =head1 SYNOPSIS use Finance::Streamer; my $user = 'USER1234'; my $pass = 'SF983JFDLKJSDFJL8342398KLSJF8329483LF'; my $symbols = 'JDSU+QCOM+AMAT+IBM+^COMPX'; my $fields = '0+1+2+3+4+8+9+21'; my $streamer = Finance::Streamer->new( user => $user, pass => $pass, symbols => $symbols, fields => $fields, ); my $sub = sub { my (%all_data) = @_; foreach my $symbol (keys %all_data) { print "$symbol\n"; my %data = %{$all_data{$symbol}}; foreach my $data_part (keys %data) { print "$data_part", "=", $data{$data_part}, "\n"; } } }; $streamer->{sub_recv} = $sub; #$streamer->receive; $streamer->receive_all; =head1 DESCRIPTION This library provides an interface that can be used to access Datek Streamer market data. It works with the new Streamer (version 3) as opposed to the older (version 2). There are four subroutines available to use. The first two, I and I, make the required tasks of connecting to a Streamer server and parsing raw quote data into an easier to use format (such as a hash) easy to do. The third, I, makes the task of using the data as easy as possible by using the previously mentioned subroutines (connect, receive). The fourth, I, is identical to I but it returns the data state. If you just want to use the data, focus on the functions I and I. If you want to know how the protocol works (roughly), focus on the I and I functions. =cut # }}} package Finance::Streamer; use strict; use warnings; use Carp; our $VERSION = '1.10'; use IO::Socket::INET; use IO::Select; use constant TRUE => 1; use constant FALSE => 0; # Default id used for connect() if nothing else is specified. my $USER_AGENT = __PACKAGE__ .

B - The raw quote data must have been received using the I value 0 or this subroutine wont work. This subroutine does not use the I object, so the name must be fully specified. The only argument that is required is a variable containing the raw data for a quote. If the parser is successful a hash containing the data will be returned. The hash will contain a key for each symbol that data was received for. Each symbol entry is a reference to another hash that has a key for each value that data is available for. A helpful tool for visualizing this is the I module. Many checks/tests are made while the data is being parsed. If something is wrong with the data, an error message will be printed to STDERR and I will be returned if the error was substantial enough that the quote data is wrong. =cut # update notification sub filter { carp "Your code needs to be updated\n".

The object attributes I, I, I, I, I, optional I and optional I must be defined before using this subroutine. $obj->{sub_recv} = $sub_ref; $obj->{sub_hrtbt} = $sub_ref_heartbeat; The I value is a reference to a subroutine to be executed when new quote data arrives. One argument, an object of parsed data as returned by I, will be passed to this subroutine. The values I, I, I, I and I are used for the I subroutine. See the section on I for more information. The I value, while it is used for I, is also used in this subroutine to specify the maximum number of seconds to wait for new data to arrive before reconnecting. The default value of B<60 seconds> is used if no value is specified. The I value is a reference to a subroutine to be executed when a B happens. One argument, the time at which the heartbeat occurred, will be passed to this subroutine when executed. Error messages may be displayed. Messages about errors receiving data will indicate why and may result in a reconnection. Messages about the status indicated in the received data are for information purposes and do not usually result in a reconnect. All messages are displayed to STDERR and so can be easily redirected.

Upon investigation I found the bug was caused due to trying to unpack before the data starts using a negative position. 1.08 Tue, 27 Aug 2002 11:56:57 -0700 * Fix of documentation errors: forgot to rename 'receive_state' to 'receive_all' in some places. Thanks to Doug Stave for finding this problem. 1.07 Wed Jan 2 16:38:23 PST 2002 - Clean up of code and documentation. 1.06 Wed May 23 23:23:17 PDT 2001 - added receive_all() subroutine that passes all the latest data instead of just the new data - a subroutine to execute when a heartbeat occurs can now be specified - changed name of subroutine filter() to Parser(), to make its purpose clearer 1.05 Wed May 23 04:33:41 PDT 2001 - bug fixes and ideas thanks to Steve Haehnichen - Changed user agent id default to an id specific to this library instead of an id of the Streamer applet. - Changed 'select' to 'fields' due to potential conflicts with reserved word 'select'. - Changed name of sub for receive() from 'sub' to 'sub_recv' to avoid potential reserved word conflicts. - Removed option to filter or not in recieve(). Was not worth the confusion it caused. - Updated documentation to reflect changes. 1.04 Tue May 22 21:06:24 PDT 2001 - bug fixes thanks to Steve Haehnichen - doc error for select 20 should have been 21. - Symbol length error for '^COMPX'. 1.03 Tue May 22 01:37:07 PDT 2001 - I added timouts for all recv() subroutines in receive(). This was required to stop the situation of waiting forever for data to arrive. - Overall cleanup of code and documentation. 1.02 Mon Apr 9 05:17:40 PDT 2001 - changed names of select values last00s -> last_size - Added a link to the Data::Dumper module in the documentation. The module is very helpful for visualizing the data returned by the "filter" subroutine. 1.01 Sat Apr 7 02:20:13 2001 - original version Finance-Streamer-1.10/test.pl0100644000175500001440000000122607617570465014772 0ustar jeriusers# Before `make install' is performed this script should be runnable with # `make test'.
