I've pulled the latest docker image and repo from github and am trying to launch paper trading on my desktop.
I've configured the config.json file as follows, and have latest IB Gateway logged into the paper trading account when I execute run_docker.bat.
"environment": "live-interactive", // "live-paper", "backtesting", "live-interactive", "live-interactive-iqfeed"
// algorithm class selector
"algorithm-type-name": "algoName",

"algorithm-language": "Python",
//Physical DLL location
//"algorithm-location": "QuantConnect.Algorithm.CSharp.dll",
"algorithm-location": "../../../Algorithm.Python/algoName.py",
// interactive brokers configuration
"ib-account": "DU----------",
"ib-user-name": "--------",
"ib-password": "------",
"ib-host": "127.0.0.1",

"ib-tws-dir": "C:\\Jts",
"ib-trading-mode": "paper",
"ib-enable-delayed-streaming-data": false,
"ib-version": "978",
However I get an unhandled exception below. Can anyone point out where I've gone wrong?

P Chen Seems you don't have the correct version of IBGateway installed.
If you installed the latest version from IB's website it's probably v980+ but in your config you set v978.
Currently IBAutomater has only been tested with v974 and v978, so I would recommend using one of these versions.
If you need them, you can download the old IBGateway versions for Linux from the QC CDN:
v974: http://cdn.quantconnect.com/interactive/ibgateway-latest-standalone-linux-x64-v974.4g.sh
v978: https://cdn.quantconnect.com/interactive/ibgateway-latest-standalone-linux-x64-v978.1c.sh
And windows:
https://cdn.quantconnect.com/interactive/ibgateway-stable-standalone-windows-x64-v978.2c.exe
P Chen
Thanks for the rpely Stefano. This is the version I installed however; its 978.2g for Windows:
https://www.interactivebrokers.com.au/en/index.php?f=16457Stefano Raggi
978.2g for Windows should work fine, I tested it myself now.
However the stack traces above seem to be from a Linux/Mono setup and you also mentioned Docker.
Are you using our latest DockerfileLeanFoundation or another setup?
https://github.com/QuantConnect/Lean/blob/master/DockerfileLeanFoundation
P Chen
Ah I think I may have gotten confused here....still fairly new to using docker
How am I meant to be using the Lean Foundation docker file? I've done nothing other than install lean and execute the the docker pull command https://hub.docker.com/r/quantconnect/lean and run the run_docker.bat file in the Lean folder after configuring config.json
Derek Melchin
Hi P Chen,
We recommend using the docker image. This is perfectly configured to run out of the box without interfering with your development environment. You can pull this image with
docker pull quantconnect/leanRefer to the full installation instructions here.
Best,
Derek Melchin

Thanks Derek but I have pulled the docker image according to the instructions already (as mentioned above). I then run the run_docker.bat file in the Lean folder but get the unhandled exception above. Was I supposed to do something with the DockerfileLeanFoundation docker file as Stefano mentioned first?
Alexandre Catarino
Hi Patrick P Chen ,
Sorry about the wait.
I was able to run Lean in live mode with IB inside a docker container.
Since the docker image is Linux, IB Gateway is installed in /roo/Jts, so we need to use the following value:
"ib-tws-dir": "/root/Jts",P Chen
