Daily Reauthentication

In TWS/ IB Gateway – “Global Configuration” – “Lock and Exit”, you can choose the time of your TWS being shut down.

For API users, it is recommended to choose “Never lock Trader Workstation” and “Auto restart”.

TWS Global Configuration window displaying Lock and Exit Settings.

Note:

  1. IBHK users do not have “Never lock Trader Workstation” and “Auto restart” in TWS. It is suggested for IBHK users to use IB Gateway in order to have stable API connection because IB Gateway won’t be locked due to inactivity. Also, IBHK users can choose “Auto restart” in IB Gateway.

Weekly Reauthentication

The weekly authentication cycle starts on every Monday. If you receive Login failed = Soft token=0 received instead of expected permanent for zdc1.ibllc.com:4001 (SSL),  this means you need to manually login again to complete the weekly reauthentication task.
