Does anyone use Merrill for trading/clearing other than Echo? We currently use Sterling and execute/clear with IB but want/need to add another option and Merrill is our next choice (yes, we have the funds), since the routing is already in place and Echo uses a similar setup. Anyone have comments on their experience with them and possibly a referral contact? Also looking at Hudson Securities if anyone has info as well. Pls PM if you prefer. Much appreciated. Thx.
