It's not IB that's the problem, its AB! I also have Ninja trader running on IB feed and ticks come in like a charm on ninja trader but not on AB.
I recently asked support if they had changed the backfill policy on ib feed and they replied they had not done so. I have my DB set to ticks and the backfill period is greyed out. before i was able to get multiple days of backfill from ib but now i only get a few minutes of backfill... very disappointing indeed! ( this means they HAVE changed backfill policy )
