IB error

[PopovDS]

Hello NT8.
Are you familiar with the error "Lost or unable to establish communications with IB TWS/GW. Please verify TWS/GW is running on the target machine and try reconnecting or contact support if the issue persists. (Panic)"? Are there any recommendations of how to avoid it?
Thank you.

I use the version of TWS shown in the attached screenshot.

I am getting same message. I submit an order get message and get disconnected from Interactive Brokers. This started happening July 1. I've submitted a support request and was eventually told it was a problem also being reported by others and they were looking in to it. It would be nice if Ninja would give an update and timeline when they expect this to be resolved.

Hello PopovDS ,

Thank you for reaching out.

In your case, your issue is being caused by TWS being updated (probably automatically) . For the bridge to work between NT8 and IB, you need to use the supported version.

When using an Interactive Brokers account to connect to NinjaTrader, you must use the version of Trader Workstation or IB Gateway that is specified within the NinjaTrader — Interactive Brokers Connection Guide seen below:

• https://support.ninjatrader.com/s/ar...language=en_US
  • TWS 10.23.2a - Download
  • IB Gateway 10.23.2a - Download
    • Please refer to the Connection Guide above for the Configuration settings of each
    • If you have another version of TWS or IB Gateway on the computer, I suggest uninstalling it first to remove confusion moving forward

Once you have the version of Trader Workstation or IB Gateway as specified above, connect to your account within TWS or IB Gateway.

• After you are connected in TWS or IB Gateway, you are then able to connect to the account within NinjaTrader.

From here connect to your account and test if the charts are updating.




Hello jasinhbca ,

Thank you for your note.

I will assume that in your case, you are on the supported version already.

For the "disconnections after order submission" issues, we are collecting the files of the impacted users to try to find a common cause.

Once we receive an update, your case will be replied through via email.

I apologize for this inconvenience and appreciate your patience in this regard.

Please let us know if I may provide any further assistance.

Erick P.,

Last month IB required me to update my account by answering what API i'm using. I think there were 3 or 4 choices. Perhaps they changed permissions effective July 1 based on what I selected. That's all I have to offer. Yes, i'm on current tws version.

Thanks, jas

Can you provide the correct version packaged for MacOS? I run TWS on a different computer than NT and connect over the LAN. I don't see a way to download a specific version on interactive brokers website. It's still working on the stable version, but who know for how long.
