Last Version of TWS to work with NT7

[Maxlobster]

Last time I upgraded TWS, NT7 did not work with it. TWS is telling me there is a new version available but I need to know what is the last version of TWS that NT7 will function with.

Hello Maxlobster,

Thank you for your post

With the current version of NinjaTrader, it is critical that you use TWS version 917. Please uninstall your existing version via the Windows Control Panel, and then install 917 via the following link:

You can view what version of TWS is supported at our Interactive Brokers connection Guide.

I'm using TWS 917.9, should I switch to 917.8?

Maxlobster,

TWS 917.9 should work without any issues.

It was when IB released 918 that there were some issues that would not allow TWS to connect to NinjaTrader.

917.8 is the version we host should anyone need to downgrade.

I've been in touch with IB & their response was:-

Please note it is the third party vendors responsibility to ensure there platform supports any and all changes IB posts to our TWS.
The reason why Ninja Trader currently does not support Build 918 and higher is because the way Ninja Trader authenticates that you are an IB customer. It essentially looks at the title bar of TWS for authentication but since IB enhanced and changed our title bar it essentially affected how Ninja Trader confirms this.
IB already has reached out to Ninja Trader and they are working on updating there platform to support the newer builds of TWS. Please check with Ninja Trader for additional details on when there next update will be available that is intended to support the latest version of TWS.

So it seems that the ball is in Ninja Trader's court to rectify this issue.

Can some urgency be placed on this fix.........it needs to be addessed ASAP.
