Currently building out an options strategy on zorro. As we are beta testing using zorro and IB as our broker, I was wondering if anyone has an idea of how to have TWS open all the time. I noticed after about a day TWS will close automatically.

IB designed the TWS software to close every night.

Now, there's a setting that lets TWS reboot every night after closing. But you still need to re-launch TWS at least once a week.

Thanks for the help !

Good luck with the trading systems
