ib_insync VS interactive-broker-python-api

Python? Then you can try: https://github.com/erdewit/ib_insync

It depends on you programming ability. Ibinsync is a good wrapper for their API though.

After some time learning the IB API, I've found the free / open source library IB_INSYNC a helpful addition making the IB TWS API easier to use from Python: https://github.com/erdewit/ib_insync

look at ib_insync. This python library is written from scratch to work with IB gateway. Unfortunately you will have to package the IB gateway with this. The headless version is way too broken to be useful. https://github.com/erdewit/ib_insync

Using Python, you can pull data from the Yahoo! Finance API 2 for free, and from IBKR's API for not-free (ib-insync is good for this). This will be a bit more work than using a plug-and-play backtester but it will give you complete control over your parameters.

The other option would be to use IBGateway. I also recall that there are utilities to manage login with IBGateway as well. The problem here is that I had a look at the IB python API and it seems awful. But perhaps ib_insync solves most of those issues? I did all this research a while back and seem to recall that ib_insync doesn't rely on the IB python code at all, right?

Interactive Brokers has an API. You can use IB_insync to access it with Python.

It's pretty clear that the Client Portal API in concert with this library, looks easy to work with from a developer's standpoint. But based on comments here from the past few months it appears that it can be flaky. So much so that a user here created a library to try to maintain the connection. But yesterday I managed to successfully stream market data for a single contract for about an hour with no issues.
