ib-insync 0.8.10

Python sync/async framework for Interactive Brokers API

Latest Version: 0.9.2


The ib_insync package is build on top of the Python API from Interactive Brokers. The objective is to make it as easy as possible to use the API to its fullest extent.

The main features are:

  • An IB component that automatically keeps in sync;
  • An easy to use linear style of programming (no more callbacks);
  • A fully asynchonous framework based on asyncio for advanced users;
  • Interactive operation with live data in Jupyter notebooks.


pip3 install -U ib_insync


To install packages needed for the examples and notebooks:

pip3 install -U jupyter numpy pandas


This is a complete script to download historical data:

from ib_insync import *

ib = IB()
ib.connect('', 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[['date', 'open', 'high', 'low', 'close']])


                   date      open      high       low     close
