zipline-live with Interactive Brokers TWS


Assuming you have Python 2.7 and virtualenv installed, you can install zipline-live using pip. If you’re using Windows, see this page for installation instructions.

virtualenv ~/venv-zipline-live
source ~/venv-zipline-live/bin/activate
pip install zipline-live[ib]

As zipline-live uses the same executable as zipline, the two projects cannot be simultaneously installed in the same environment.

Create a simple algorithm

Save the following code to ~/zipline-algos/ This simple algorithm logs the AAPL prices.

from zipline.api import order, symbol

import logbook
log = logbook.Logger('algo')

def initialize(context):

def handle_data(context, data):
    sym = symbol("AAPL")"handle_data: last_traded={} price={} OHLC={}/{}/{}/{} Volume={}".format(
        data.current(sym, 'last_traded'),
        data.current(sym, 'price'),
        data.current(sym, 'open'),
        data.current(sym, 'high'),
        data.current(sym, 'low'),
        data.current(sym, 'close'),
        data.current(sym, 'volume')))
