profitpy on debian

[tavi]

Hi,

I'm trying to install profitpy 0.1 (stable) on debian testing (lenny).
Is there a list of required packages from the repositories and/or
additional libraries needed for this to work?
Has anybody tried this before?

Thanks,
Tavi

It uses PyQwt... and, of course, Qt... but it "just worked" for me, I
think... although qwt "might" have required some tinkering IIRC.

I have this installed from the repositories:
python-qwt5-qt4 (5.1.0.dfsg-1)

However when I try to run the command "python bin/strategy_designer" I
get the following:

Traceback (most recent call last):

Do I have to install pyqwt/qt from sources?

What version of Qt/PyQt? You should use 4.4 if you can.

That would be best.

I just ran into this bug... on Windows. It looks like something isn't
generated correctly via pyuic4. I'll either work around it in the ui
file or find the underlying bug. In both cases, I'll let you know
about a permanent fix.

In the mean time, just open up ui_callableselect.py (not ui) and
comment out every line that begins "self.callableType.addItem(icon".

Looks like it's been fixed, just not in a release (I can certainly sympathize :)

Thanks for the quick replies !

With this change and some debian packages installed (python2.5, python-
qwt5-qt4, pyqt4-dev-tools and all dependencies) I managed to get the
GUI up and running. I also installed IbPy from sources. Do I need any
other packages/libraries? (I've seen some posts mentioning
java2python, antlr, etc.)

I have a few basic questions about using the software:
How do I do backtesting?
Where does it get the historical data?
Do I need an IB account to use a particular feature? Can I do anything
without an IB account?

I guess a better question would be if there is an user's manual
somewhere?

You'll need scipy, too.

> How do I do backtesting?

Connect to TWS, let it run for a while, then save the session. Close
the profit device and restart it. Load your strategy (you're on your
own here -- use the shell), then import your saved session. The tool
will re-send each TWS message thru the system and your code can pick
them up.

You can also use the same approach without saving a session -- load
your code, then connect to the demo TWS. As the app creates message
objects, your code can react by placing orders (or doing whatever it
is that you want).

> Where does it get the historical data?

From previous sessions. You have to save them yourself.

You can use the demo account. Both edemo and fdemo accounts work.

Patches welcome. :)

I got the the demo version (w/ edemo account) of the TWS working but
the connection from the profit_device fails with the message:
reqMktData() takes exactly 4 arguments (5 given)

Any ideas?

Thanks,

What revision of profitpy and ibpy? In both cases, update to the
latest sources if you can.

I updated ibpy to the latest version in svn and now the connection to
the IB tws seems to work fine.
It looks like the stable IbPy-0.7.4-9.20 from the download page is no
longer compatible with the latest version of the tws
