ANN: IbPy 0.5 - Interactive Brokers Python API
by Troy Melhase 25 Dec '05

25 Dec '05

IbPy - Interactive Brokers Python API ===================================== IbPy 0.5 Released 25 December 2005 What is IbPy? ------------------------------------------------------------------------------ IbPy is a third-party implementation of the API used for accessing the Interactive Brokers on-line trading system. IbPy implements functionality that the Python programmer can use to connect to IB, request stock ticker data, submit orders for stocks and futures, and more. What's new in this release? ------------------------------------------------------------------------------ The focus of this release is compatibility with recent versions of the TWS application. TWS Build 851.9 is the most recent release tested. This 0.5 release marks the first version with run time activity logging. The feature is turned on by default. Users wanting to turn the feature off should refer to the source documentation. Where can I get IbPy? ------------------------------------------------------------------------------ IbPy is available for download from SourceForge.net. http://sourceforge.net/project/showfiles.php?group_id=53862 Project page: http://ibpy.sourceforge.net/ How do I use IbPy? ------------------------------------------------------------------------------ In order to use IbPy, the TWS application provided by IB must be installed and running. See the note "What is TWS?" for more information. IbPy is used in the same manner as all socket clients supplied by Interactive Brokers. The typical sequence of operations is: * Start the browser-based or stand-alone TWS application * In TWS, enable socket clients via the Configure -> API menu * Connect to TWS from external application * In TWS, accept the incoming connection * External application requests ticker updates, sends orders, receives account data, portfolio data, etc. To connect to TWS and interact with the brokers trading system, the Python developer defines methods or functions to act as callbacks and associates these with an Ib.Socket.SocketConnection object. Refer to the Demo.py file in the distribution for a complete example. In lieu of IbPy documentation, developers are referred to the IbPy source code and the documentation supplied by Interactive Brokers. What are the requirements? ------------------------------------------------------------------------------ IbPy requires Python 2.3 or newer. Previous versions may or may not work. TWS requires a web browser capable of executing Sun(R) Java(tm) applets. TWS can also be started directly with Sun(R) Java(tm) and the stand-alone package supplied by Interactive Brokers. What is Interactive Brokers? ------------------------------------------------------------------------------ >From the "About The Interactive Brokers Group" page (http://interactivebrokers.com/html/companyInfo/about.html): The Interactive Brokers Group is a group of electronic brokerage and market making firms at the forefront of the electronic brokerage industry. We have revolutionized the securities and derivatives markets by providing investors with high-speed, direct access to stock, options and futures products worldwide. We specialize in providing investors with technology that offers efficient, fast access to the world's markets at the lowest possible cost. What is Python? ------------------------------------------------------------------------------ >From the "What is Python?" page (http://python.org/doc/Summary.html): Python is an interpreted, interactive, object-oriented programming language. It is often compared to Tcl, Perl, Scheme or Java. Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac, MFC). New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface. The Python implementation is portable: it runs on many brands of UNIX, on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't listed here, it may still be supported, if there's a C compiler for it. Ask around on comp.lang.python -- or just try compiling Python yourself. The Python implementation is copyrighted but freely usable and distributable, even for commercial use. What is TWS? ------------------------------------------------------------------------------ >From the page "Trader Execution and Clearing System Features" (http://interactivebrokers.com/html/companyInfo/market_ib.html): * IB's Trader Workstation can be run directly from your browser, or you can install it on your PC and run it from your desktop. This Java based application allows traders to quickly enter orders and see results. * Direct Access: Unlike other "online" brokers that send your order through an e-mail type system, IB offers a direct-access order entry system that transmits your order to the proper market center, usually within one second of entry. * Real-Time Streaming Quotes: Display real-time, streaming quotes for markets of interest to the investor. Quotes are live and change continuously as the markets change, no periodic manual update or "refresh" is required. What Else? ------------------------------------------------------------------------------ IbPy is not a product of Interactive Brokers, nor am I affiliated with IB. I am a satisfied IB customer, of course. IbPy is installed with distutils. Refer to the Python distutils documentation for more information. The digest version is: # tar xzf IbPy-0.5.tar.gz # cd IbPy-0.5 # python setup.py install The TWS demo system is available here: http://interactivebrokers.com/cgi-pub/jtslink.pl?user_name=edemo The stand-alone TWS and other API software is available from IB: http://interactivebrokers.com/ IbPy is licensed under the BSD License. I'm very interested in your experience with IbPy. Please drop me an note with any feedback you have. Troy Melhase mailto:troy@gci.net

by garabik-news-2005-05＠kassiopeia.juls.savba.sk 23 Dec '05

23 Dec '05

mountpy is a python script for quick automatic mounting and umounting of external filesystems, especially suited for USB removable devices. mountpy is developed on linux, and is meant for modern linux systems. This is version 0.4, changes from previous version: - do not remove the directories when umounting (caused some problems with gnome and kde) - use filesystem type explicitely during mount - remove 'sync' option from the defaults - 2.6.14 kernel finally implemented the 'sync' for vfat filesystem, but with terrible performance (read: completely unusable) URL: http://kassiopeia.juls.savba.sk/~garabik/software/mountpy/ License: GPL -- ----------------------------------------------------------- | Radovan Garabík http://kassiopeia.juls.savba.sk/~garabik/ | | __..--^^^--..__ garabik @ kassiopeia.juls.savba.sk | ----------------------------------------------------------- Antivirus alert: file .signature infected by signature virus.

[ANN] python-dateutil 1.1
by Gustavo Niemeyer 23 Dec '05

23 Dec '05

Changes since 1.0 ----------------- - Fixed rrule byyearday handling. Abramo Bagnara pointed out that RFC2445 allows negative numbers. - Fixed --prefix handling in setup.py (by Sidnei da Silva). - Now tz.gettz() returns a tzlocal instance when not given any arguments and no other timezone information is found. - Updated timezone information to version 2005q. What is it? ----------- The dateutil module provides powerful extensions to the standard datetime module, available in Python 2.3+. Features -------- * Computing of relative deltas (next month, next year, next monday, last week of month, and a lot more); * Computing of relative deltas between two given date and/or datetime objects; * Computing of dates based on very flexible recurrence rules (every month, every week on Thursday and Friday, every Friday 13th, and a *LOT* more), using a superset of the iCalendar RFC specification. Parsing of RFC strings is supported as well. * Generic parsing of dates in almost any string format; * Timezone (tzinfo) implementations for tzfile(5) format files (/etc/localtime, /usr/share/zoneinfo, etc), TZ environment string (in all known formats), iCalendar format files, given ranges (with help from relative deltas), local machine timezone, fixed offset timezone, UTC timezone, and Windows registry-based timezones. * Internal up-to-date world timezone information based on Olson's database. * Computing of Easter Sunday dates for any given year, using Western, Orthodox or Julian algorithms; * More than 450 test cases.

ANN: PyTables 1.2.1
by Francesc Altet 22 Dec '05

22 Dec '05

========================= Announcing PyTables 1.2.1 ========================= I'm happy to announce a new version of PyTables. This is a maintenance version and only bugs has been fixed in it. In particular, the documentation has not change at all, so it is not necessary that you look at it for changes. Go to the PyTables web site for downloading the beast: http://pytables.sourceforge.net/ or keep reading for more info about the bugs fixed in this version. I take the opportunity to announce as well that PyTables is adopting the bazaar-ng (http://www.bazaar-ng.org/) distributed version control, in order to easy the contributions from developers throughout the world. See more info about this new facility (currently in beta) in: http://sourceforge.net/mailarchive/forum.php?thread_id=9253854&forum_id=137… Changes more in depth ===================== Bug fixes: - Table.flush() is called automatically before disposing a table object from the user space. This avoids a problem that appears when the user does not explicitely do the flush and the table is unbounded and rebounded after on (using h5file.getNode() for example). - A small typo has been fixed in the ptrepack utility. This prevented ptrepack from working correctly when asking for statistics on operations done (-v flag). Known issues: - Time datatypes are non-portable between big-endian and little-endian architectures. This is ultimately a consequence of an HDF5 limitation. See SF bug #1234709 for more info. Backward-incompatible changes: - None. Important note for MacOSX users =============================== From PyTables 1.2 on, the UCL compressor seems to work well again on MacOSX platforms. We don't know exactly why, but the fact is that all the test suite passes (using UCL) executes flawlessly. So, from now on, support for UCL in MacOSX is enabled again by default (i.e. you don't need to use the flag ``--force-ucl``, which has disappeared). Important note for Python 2.4 and Windows users =============================================== If you are willing to use PyTables with Python 2.4 in Windows platforms, you will need to get the HDF5 library compiled for MSVC 7.1, aka .NET 2003. It can be found at: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-165-win-net.ZIP Users of Python 2.3 on Windows will have to download the version of HDF5 compiled with MSVC 6.0 available in: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-165-win.ZIP What it is ========== **PyTables** is a package for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data (with support for full 64-bit file addressing). It features an object-oriented interface that, combined with C extensions for the performance-critical parts of the code, makes it a very easy-to-use tool for high performance data storage and retrieval. PyTables runs on top of the HDF5 library and numarray (Numeric is also supported) package for achieving maximum throughput and convenient use. Besides, PyTables I/O for table objects is buffered, implemented in C and carefully tuned so that you can reach much better performance with PyTables than with your own home-grown wrappings to the HDF5 library. PyTables sports indexing capabilities as well, allowing doing selections in tables exceeding one billion of rows in just seconds. Platforms ========= This version has been extensively checked on quite a few platforms, like Linux on Intel32 (Pentium), Win on Intel32 (Pentium), Linux on Intel64 (Itanium2), FreeBSD on AMD64 (Opteron), Linux on PowerPC and MacOSX on PowerPC. For other platforms, chances are that the code can be easily compiled and run without further issues. Please, contact us in case you are experiencing problems. Resources ========= Go to the PyTables web site for more details: http://pytables.sourceforge.net/ About the HDF5 library: http://hdf.ncsa.uiuc.edu/HDF5/ About numarray: http://www.stsci.edu/resources/software_hardware/numarray To know more about the company behind the PyTables development, see: http://www.carabos.com/ Acknowledgments =============== Thanks to various the users who provided feature improvements, patches, bug reports, support and suggestions. See THANKS file in distribution package for a (necessarily incomplete) list of contributors. Many thanks also to SourceForge who have helped to make and distribute this package! And last but not least, a big thank you to THG (http://www.hdfgroup.org/) for sponsoring many of the new features recently introduced in PyTables. Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. ---- **Enjoy data!** -- The PyTables Team

PyPy Sprint Palma de Mallorca in January 2006
by Carl Friedrich Bolz 22 Dec '05

22 Dec '05

Palma de Mallorca PyPy Sprint: 23rd - 29th January 2006 ============================================================ The next PyPy sprint is scheduled to be in January 2006 in Palma De Mallorca, Balearic Isles, Spain. We'll give newcomer-friendly introductions. Its focus will mainly be on the current JIT work, garbage collection, alternative threading models, logic programming and on improving the interface with external functions. To learn more about the new PyPy Python-in-Python implementation look here: http://codespeak.net/pypy Goals and topics of the sprint ------------------------------ In Gothenburg we have made some first forays into the interesting topics of phase 2 of the PyPy project. In Mallorca we will continue the work that we started there. The currently scheduled main topics are: - Further work/experimentation with the Abstract Interpreter that was started in Gothenburg. - Integrating our garbage collection toolkit with the backends and the code generation. - Heading into the direction of adding logic programming to PyPy. - Optimization work: our threading implementation is still incredibly slow, we need to work on that. Furthermore there are still quite some slow places in the interpreter that could be improved. - If someone feels like it: although vastly improved our socket module is still far from complete - In general we need to improve the way we interface with external functions. Location & Accomodation ------------------------ The sprint will be held at the Palma University (UIB - Universitat de les Illes Balears), in their GNU/Linux lab (http://mnm.uib.es/phpwiki/AulaLinux). We are hosted by the Computer Science department and Ricardo Galli is our contact person there, helping with arranging facilities. The University is located 7 km away from the central Palma. Busses to the University departs from "Plaza de España" (which is a very central location in Palma). Take bus 19 to the UIB campus. A ticket for one urban trip costs 1 euro. You can also buy a card that is valid for 10 trips and costs 7.51 euros. Information about bus timetables and routes can be found on: http://www.a-palma.es. A map over the UIB campus are can be found on: http://www.uib.es/imagenes/planoCampus.html The actual address is: 3r pis de l'Anselm Turmeda which can be found on the UIB Campus map. At "Plaza de España" there is a hostel (Hostal Residencia Terminus) which has been recommended to us. It's cheap (ca 50 euros/double room with bathroom). Some more links to accomodations (flats, student homes and hotels): http://www.lodging-in-spain.com/hotel/town/Islas_Baleares,Mallorca,Palma_de… http://www.uib.es/fuguib/residencia/english/index.html http://www.homelidays.com/EN-Holidays-Rental/110_Search/SearchList.asp?DEST… LOCALISATION=ES%20ISLASBALEARES%20MALLORCA If you want to find a given street, you can search here: http://www.callejeando.com/Pueblos/pueblo7_1.htm To get to Palma De Mallorca almost all low fare airlines and travel agencies have cheap tickets to get there. Information about Mallorca and Palma (maps, tourist information, local transports, recommended air lines, ferries and much more) can be found on: http://www.palmademallorca.es/portalPalma/home.jsp Comments on the weather: In January it is cold and wet on Mallorca Average temperature: 8,4 degrees Celsius Lowest temperature: 2 degrees Celsius Highest temperature: 14,5 degrees Celsius Average humidity rate: 77,6 % So more time for coding and less time for sunbathing and beaches ;-) Exact times ----------- The public PyPy sprint is held Monday 23rd - Sunday 29th January 2006. Hours will be from 10:00 until people have had enough. It's a good idea to arrive a day before the sprint starts and leave a day later. In the middle of the sprint there usually is a break day and it's usually ok to take half-days off if you feel like it. For this particular break day, Thursday, we are invited to the studio of Ginés Quiñonero, a local artist and painter. Ginés have also been the person helping us getting connections to UIB and providing much appreciated help regarding accommodation and other logistical information. For those of you interested - here is his website where there also are paintings showing his studio: http://www.hermetex4.com/damnans/ For those interested in playing collectable card games, this will also be an opportunity to get aquainted with V:TES which will be demoed by Ginés and Beatrice and Sten Düring. For more information on this cardgame - see: http://www.white-wolf.com/vtes/index.php. (The Mallorca sprint was organized through contacts within the V:TES community). Network, Food, currency ------------------------ Currency is Euro. Food is available in the UIB Campus area as well as cheap restaurants in Palma. You normally need a wireless network card to access the network, but we can provide a wireless/ethernet bridge. 230V AC plugs are used in Mallorca. Registration etc.pp. -------------------- Please subscribe to the `PyPy sprint mailing list`_, introduce yourself and post a note that you want to come. Feel free to ask any questions there! There also is a separate `Mallorca people`_ page tracking who is already thought to come. If you have commit rights on codespeak then you can modify yourself a checkout of http://codespeak.net/svn/pypy/extradoc/sprintinfo/mallorca-2006/people.txt .. _`PyPy sprint mailing list`: http://codespeak.net/mailman/listinfo/pypy-sprint .. _`Mallorca people`: http://codespeak.net/pypy/extradoc/sprintinfo/mallorca-2006/people.html

PyCon: Two weeks left for early-bird registration
by A.M. Kuchling 20 Dec '05

20 Dec '05

Early bird registration for PyCon ends on December 31st, so there's now slightly less than two weeks left. To register, go to: http://us.pycon.org/TX2006/Registration You can still register after Dec. 31st, but the cost will go up by US$65 (US$25 for students). Course outlines have now been posted for all the tutorials; see http://wiki.python.org/moin/PyCon2006/Tutorials All of the PyCon tutorials are still open for new registrations, but space is limited, and I suspect they'll all be filled up by the time early-bird registration closes. Don't forget to book your hotel room, too: http://us.pycon.org/Addison/Hotels A.M. Kuchling Chair, PyCon 2006 amk(a)amk.ca
