When market closed, I login into TWS desktop, then it looks like the quantopian will disconnect the IB account. Then I close the TWS, and check the quantopian page, the live webpage looks all the same . How do I know I am connected to the IB through quantopian? Does the stock position status imply whether I am correctly connected?(The setting page shows Status: Broker Login Needed)? Maybe where can i login in again??
