Introduction

The goal of the IB-insync library is to make working with the
Trader Workstation API <http://interactivebrokers.github.io/tws-api/>_
from Interactive Brokers as easy as possible.

The main features are:

An easy to use linear style of programming;
An IB component <https://ib-insync.readthedocs.io/api.html#module-ib_insync.ib>_
that automatically keeps in sync with the TWS or IB Gateway application;
A fully asynchonous framework based on
asyncio <https://docs.python.org/3/library/asyncio.html>_
and
eventkit <https://github.com/erdewit/eventkit>_
for advanced users;
Interactive operation with live data in Jupyter notebooks.

Be sure to take a look at the
notebooks <https://ib-insync.readthedocs.io/notebooks.html>,
the recipes <https://ib-insync.readthedocs.io/recipes.html>
and the API docs <https://ib-insync.readthedocs.io/api.html>_.

Installation

pip install ib_insync

For Python 3.6 install the dataclasses package as well
(newer Python versions already have it)::

pip install dataclasses

Requirements:

Python 3.6 or higher;
A running TWS or IB Gateway application (version 972 or higher).
Make sure the
API port is enabled <https://interactivebrokers.github.io/tws-api/initial_setup.html>_
and 'Download open orders on connection' is checked.

The ibapi package from IB is not needed.

Example

This is a complete script to download historical data:

.. code-block:: python

from ib_insync import *
# util.startLoop()  # uncomment this line when in a notebook

ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1)

contract = Forex('EURUSD')
bars = ib.reqHistoricalData(
    contract, endDateTime='', durationStr='30 D',
    barSizeSetting='1 hour', whatToShow='MIDPOINT', useRTH=True)

# convert to pandas dataframe:
df = util.df(bars)
print(df)

Output::

Consultancy & Development

IB-insync offers an easy entry into building automated trading systems
for both individual traders and fintech companies. However, to get the most out
of it is not a trivial matter and is beyond the reach of most developers.

If you need expert help, you can contact me. This can be for a small project,
such as fixing something in your own code, or it can be creating an entire new
trading infrastructure.
Please provide enough details so that I can assess both the feasibility and
the scope. Many folks worry about having to provide their 'secret sauce',
but that is never necessary (although you're perfectly welcome
to send that as well!)
