Cannot connect to TWS API

[katanisk8]

Hi

My docker-compose setup of TWS:

Container is successfully created and I can open TWS and see trades etc:

I'm trying connect to TWS using provided EClientSocket from TWS API. Using host: ikbr, port: 8888 (tried use host as localhost, 127.0.0.1, host.docker.internal etc. nothing helped):

I am not getting any error but IsConnected() method at line 42 all time returning me false.

In ikbr container logs I can see thet connection to 127.0.0.1:7496 is refused:

What I'm doing wrong?

Try adding IBC_AcceptIncomingConnectionAction: accept to the environment key:

  ibkr:
    image: ghcr.io/extrange/ibkr:stable
    ports:
      - 6080:6080
      - 8888:8888
    restart: always
    ulimits:
      nofile: 10000
    environment:
      IBC_AcceptIncomingConnectionAction: accept

Still same:

@extrange Trusted APIs must be provided in global configuration. How to do this via env in docker?

[extrange]

That's strange, I'm using ib_insync and I have no problems connecting to the API, I'm not sure if this could be an issue with the C# library you're using.

You didn't specify IBC_TradingMode - by default, live is used - is your username and password for a live account?

What do you mean by trusted APIs - do you mean trusted incoming connections?

[katanisk8]

To local trader workstation I'm login to live account:

But if app is launched I can see that this is paper account:

Trusted APIs I mean options in global configuration -> API -> Settings:

[extrange]

Ok. By default, the paper account is used (even if a live username is provided). Can you add the following to your config and try again?

GATEWAY_OR_TWS: tws
IBC_TradingMode: live

socat in the container will forward the API connection automatically, so external connections will appear as localhost to TWS. There is therefore no need to specify trusted IPs.

[katanisk8]

Still connection refused:

[extrange]

Can you run the following and paste the output?

docker exec $(docker ps | awk '/ibkr/ {print $1}') bash -c 'apt-get install -qy iproute2 && ss -antp'

@extrange any idea?

[peter-hartmann]

When using tws (default) then the '''Enable Active and Socket Clients''' option needs to be checked under '''File>Global Configuration...>API'''. Then it works. Not sure if this can be set as environment variable....

[extrange]

Yup, that's correct. Specifically this needs to be ticked (Enable ActiveX and Socket Clients)

Unfortunately, IBCAlpha does not do this (issue). At this point, I'm afraid you'll have to manually set it, or otherwise use IBGateway (it automatically has the API enabled).

Closing this issue, as it is out of scope for this repository.

Unfortunately, IBCAlpha does not do this (https://github.com/IbcAlpha/IBC/issues/120). At this point, I'm afraid you'll have to manually set it, or otherwise use IBGateway (it automatically has the API enabled).

How should I manually set ? Using VNC UI?

[extrange]

Yup, on the VNC web client at localhost:6080. To persist it, you can volume mount the resulting ibg.xml in /root/Jts/<long random string>.
