I use Sterling. I just got back to sterling after a few months and it's got some new routes I haven't seen before. Also NYSE route and NY/AM do not work for me (they say it's disabled). In the meantime I have been using NSDAQDDOT but there must be a cheaper route? Anyone help with the best routes and if you know the fees for certain routes.
