Interactive Brokers API Connection Error
显示 更早的评论
I just installed the Trading Toolbox 2017b and the IB API 9.73 Windows 10. I keep getting this error:
ib = ibtws('',7496);
Error using actxserver (line 90) Server creation failed. Invalid ProgID 'TWS.TwsCtrl.1'.

I have the 9.74 IB API and Matlab 2018b release. The bug persists.
>> ib = ibtws('',7496,1)
Error using actxserver (line 93)
Server creation failed. Invalid ProgID 'TWS.TwsCtrl.1'.
Error in ibtws (line 37)
x.Handle = actxserver('TWS.TwsCtrl.1');

Hey Troy ,
Thanks for the tip. nevertheless, I'm still in the woods here. I used the command you pointed out but it looks like there's no ActiveX controller for TWS. I'm not much of a file reader but I suppose it should Display TWS somewhere...and also, I've been told by Technical support at IB that 9.74 enhances 9.73, so If the fix works on 9.73, it should work on 9.74. Anyway, this is the nth time I have to struggle with this issue in the last 3 years. I'dlike to talk with Amy but there's no way of contacting matlab support about any of this issues.

Sometime in recent years, presumably around API version 9.70, IB changed their COM server's ProgID from 'TWS.TwsCtrl.1' to 'TWS.TwsCtrl'. This breaks the Trading Toolbox code, which assumes a ProgId of 'TWS.TwsCtrl.1'. Since the Trading Toolbox's code is encrypted, you cannot modify its expected ProgId. The best that you can do is to try to uninstall your API and install an old version (possibly with IB's assistance). Note that this might break other things for you - the old API version might not be fully supported by IB today, but it's worth trying. See also this answer about the exact same problem.
Or you can try my Java-API-based IB-Matlab connector which does not rely on COM and does not exhibit any of the problems that are common with the ActiveX/COM-based interface.
