Eddie Hebert 799a357d98 Changes test factory to use Event instead of ndict.
As more sources are moving off of ndict,
changing the factory to use Event, so that when testing we are
exercising use of Event.

Richard FrankandEddie Hebert 4981c67c31 Handle missing historical data more elegantly
Updated the search for treasury data when there is none for the
test end date.
It could be that the end date is not a trading day, or we could
just be missing treasury data. In either case, we try to recover
more gracefully now, by searching as far as possible and maybe
logging a warning.

Similarly, if there is no benchmark data for the test end date,
look for the next trading day. If we really have no data,
blow up with our own explicit exception, instead of overflowing
in our search for dates in the future.

Thomas Wiecki 5f6839beea BUG: Refactored batch_transform unittests and fixed some bugs. 2012-12-06 12:36:47 -05:00
Eddie Hebert 3ff3a6964e Allows the capital base of an algorithm to be more easily modified.
By having run() use a capital_base member of the algorithm to
create the trading environment, the capital base should now be
configurable in the instantiation of the algorithm.

e.g.:

```
algo = LowCapitalBaseAlgorithm(capital_base=1000.0):
```

Eddie Hebert 8a0d6e72cd Changes the location of downloaded external data files.
So that the zipline library can be used when installed to a
write-protected location, e.g. the global site-packages,
moving the download files to a directory in the user's path,
which should be writeable.

For now, choosing a ~/.zipline/data location.

Thomas WieckiandEddie Hebert 15ac658024 Restructured file hierarchy. Transforms now live in transforms (transform.py is now transforms/utils.py). Sources are in sources.py. VWAP is now MovingVWAP. 2012-10-19 18:10:51 -04:00
Eddie Hebert 0ab136f1c8 Adds a loader for market data when it doesn't exist locally.
Hopefully, this helps ease ramp up time for developing against
market data, without us distributing the data.

We do a check for the data when attempting to read the msgpack
files, if they don't exist the loader makes a web request and
retrieves and serializes the data for the user.

Provides a loader for:

- curves from data.treasury.gov
- benchmarks from Yahoo! Finance

Adds dependency of requests library in dev requirements.

Eddie Hebert 77af1ca632 Applies PEP-8 and pyflakes style to tests and zipline.
Mostly whitespace, line width and other spacing changes.
Also, removes use of deprecated has_key in favor of `in`

Going forward new patches should pass running `flake8` before
submission.
