I have used that Ninja with IB data feed for over a year. I went away for 6 weeks, came back, updated my IB TWS as the old version is not longer supported. I have Ninja 7 and didn't do any update. For some reason, now Ninja cannot connect to IB datafeed any more. I went to tools and check settings. It would start my TWS and log me in though, this is something Ninja did not use to do. Anyone has any suggestion?
