Running Interactive Brokers with native Python support seems to be a pain in the ass. As I see it, I will continue with the methodologies I show in my Interactive Brokers API course. It seems that using Python 3 on Mac is a real pain so I am not bothered to fully implement or install until there is an official document to show to to implement. It seems that this current API version is not fully stable but only experimental.

What I will do

As for me, I will continue with the same path in using Redis NOSQL for the central data hub. We can connect Redis with either C++ or Java to interface with Interactive Brokers Treader Workstation (TWS). I shall stick with this for many reasons as we currently sit.

I have included some useful URL tips if you are interested. Pleaseunderstand I get frustrated with all these unofficial ways to implement.  I will just stick with the current non Python techniques I have.

# Gist example of IB wrapper …
#
# Download API from http://interactivebrokers.github.io/#
#
# Install python API code /IBJts/source/pythonclient $ python3 setup.py install
#
# Note: The test cases, and the documentation refer to a python package called IBApi,
# but the actual package is called ibapi. Go figure.
#
# Get the latest version of the gateway:
# https://www.interactivebrokers.com/en/?f=%2Fen%2Fcontrol%2Fsystemstandalone-ibGateway.php%3Fos%3Dunix
# (for unix: windows and mac users please find your own version)
#
# Run the gateway
#
# user: edemo
# pwd: demo123
#
# Now I'll try and replicate the time telling example

Interactive Brokers makes new API available for Python programmers

Interactive Brokers makes new API available for Python programmers

https://www.elitetrader.com/et/threads/ib-native-python-api-for-dummies.307989/

I am sure this will get hammered out over the next few months. Note that this API client release (with the Python client) is not stable. As a result, I will not even enter the fray of playing around with this until there is a stable release you can download.

NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
