*Python module to get stock data from the Alpha Vantage API*
Alpha Vantage delivers a free API for real time financial data and most
used finance indicators in a simple json format. This module implements
a python interface to the free API provided by Alpha Vantage
(http://www.alphavantage.co/). It requires a free API, that can be
requested on http://www.alphavantage.co/support/#api-key.
Install
-------
To install the package use:
.. code:: shell
pip install alpha_vantage
If you want to install from source, then use:
.. code:: shell
git clone https://github.com/RomelTorres/alpha_vantage.git
pip install -e alpha_vantage
Usage
-----
To get data in a python, simply import the library and call the object
with your api key and get ready for some awesome free realtime finance
data.
.. code:: python
from alpha_vantage.timeseries import TimesSeries
ts = TimesSeries(key='YOUR_API_KEY')
# Get json object with the intraday data and another with the call's metadata
data, meta_data = ts.get_intraday('GOOGL')
Internally there is a retries counter, that can be used to minimize
connection errors (in case that the api is not able to respond in time),
the default is set to 5 but can be increased or decreased whenever
needed.
.. code:: python
ts = TimesSeries(key='YOUR_API_KEY',retries='YOUR_RETRIES')
Finally the library supports giving its results as json dictionaries
(default) or as pandas dataframe, simply pass the parameter
output\_format='pandas' to change the format of the output for all the
api calls.
.. code:: python
ts = TimesSeries(key='YOUR_API_KEY',output_format='pandas')
Plotting
--------
Using pandas support we can plot the intra-minute value for 'MSFT' stock
quite easily:
.. code:: python
from alpha_vantage.timeseries import TimesSeries
import matplotlib.pyplot as plt
ts = TimesSeries(key='YOUR_API_KEY', output_format='pandas')
data, meta_data = ts.get_intraday(symbol='MSFT',interval='1min', outputsize='full')
data['close'].plot()
plt.title('Intraday Times Series for the MSFT stock (1 min)')
plt.show()
Giving us as output: |alt text|
The same way we can get pandas to plot technical indicators like
Bolliger Bands®
.. code:: python
from alpha_vantage.techindicators import TechIndicators
import matplotlib.pyplot as plt
ti = TechIndicators(key='YOUR_API_KEY', output_format='pandas')
data, meta_data = ti.get_bbands(symbol='MSFT', interval='60min', time_period=60)
data.plot()
plt.title('BBbands indicator for MSFT stock (60 min)')
plt.show()
Giving us as output: |alt text|
Tests
-----
In order to run the tests you have to first export your API key so that
the test can use it to run.
.. code:: shell
export API_KEY=YOUR_API_KEY
cd alpha_vantage
nosetests
Documentation
-------------
To find out more about the available api calls, visit the alpha-vantage
documentation at http://www.alphavantage.co/documentation/
