I can no longer reconnect to Interactive Brokers after Trader Workstation automatically reboots overnight. It forces me to restart WL7 and rerun everything in strategy monitor. Has something changed with the interactive brokers extension?
Rename
Sure, it's changing a lot lately, and there's a lot more to come in Build 18.
IB's C# API doesn't report a disconnect as documented. I've got a ticket with IB on it that has been ignored. In any case, we'll keep looking on improving.
To work around TWS's forced restart, can't you schedule Wealth-Lab to restart at the same time? Or do this during the day when the session closes?

Thanks for responding Cone. Not much you can do if it is an API issue. I tend not to restart WL7 except for weekends. The Strategy Monitor takes about 1.5 hours to activate all my strategies at this point which is why restarting WL is such a pain.

I'm doing all I can to make reconnection work following a TWS Restart, but at this point I can't say it's going to be reliable. :(
fyi,
IB Build 18 will have Streaming Bars. The main advantage is that the data will actually match historical bars, and, the processing footprint will be reduced since updates to the Streaming Bar occur only every 5 seconds.
Note that if you use IB Streaming, data are conflated (updated 250msec max for stocks). Consequently, you don't get the actual tick-by-tick updates that IB (or any other provider) uses to create the historical bars, resulting in minor differences in bar prices with respect to the historical bars.

I am seeing a similar problem where I can't connect to IB this morning. (It was working yesterday.) I am getting the following error message in the Order manager when I try to connect.
Auto Launch IB TWS is checked in data manager for both Historical and Streaming Providers.
I've tried every combination of restarting TWS and WL8. I then shut both down, started WL8 and it auto-started TWS. After successful login. I still got the above error message.
Please suggest what you think I should try to get connected.

Forget about Auto-Launch and Start TWS first and connection will always work.
Background -
Starting TWS takes a LONG time - nearly a minute on my machine. If connection fails because TWS isn't ready to accept a connection, you have to wait at least 30 seconds before trying again. Unfortunately, I think reconnection logic is fighting with this new rule imposed, so you might have to wait even longer. We'll try to make that more seamless in the future.

I did what you prescribed but still can't connect. Sometimes the Connect button is green and sometimes it is greyed out (like now). I even restarted my computer.
I do get the following message if that is helpful in troubleshooting.
Then I shut down TWS again, and waited a minute or two after login to launch WL* and try Connect. This time the button was green but got the original fail message.
No luck connecting so far this AM.

I certainly didn't prescribe shutting down TWS after connecting. Why would you do that?

Well, I couldn't connect even after I followed your instructions, so I tried to start from scratch, thinking maybe IB had a flag set that thought it was connected (although WL8 did not.) Just trying everything I could think of to try to get connected.
This morning I have been able to connect. Not sure what was different about yesterday and today. Not aware of anything I did differently.
If there's a problem connecting, restart Wealth-Lab, not TWS. TWS needs to be ready to receive the connection. If TWS is ready and the API configurations are properly set up, it will connect every time, quickly.
Are there any updates on this issue? Last night I oversaw the restart and WL entered a trade and everything seemed fine, but this morning I found that the Auto-Place button was toggled off and it missed trades.
Also I should note: There are no messages at all in the log during this period.
Additional note: I did not restart WL after TWS restarted. But I assumed it was working because I checked before going to bed.

QUOTE:That's a different problem. I don't know what would cause the Auto-Place button to toggle except by clicking it or loading a workspace that has it disabled.

Ok. Its possible I will have better luck with strategy manager, but I haven't quite figured out how to make it work for me yet. The only way I have gotten a strategy to work is dragging it onto a chart. I am very new to the software, so hopefully its just something I am doing wrong. However, it remains a mystery. I am pretty sure it is related to the restart. I will also implement the auto restart on WL end as soon as I can figure out how to get WL to auto-initiate my strategies upon boot up.
Have you signed up for our monthly Getting to Know WL Webinar? Check the home page for details.
Is there a solution to this problem planned? For strategies that have to work 24 hours a day, the current approach is extremely unreliable. I understand that IB forces us to come up with crooked solutions
1. Schedule your IB restart
2. After that, use the Task Scheduler to restart Wealth-Lab to your saved trading Workspace.
Should work.
