I can absolutely confirm that Ameritrade has not been accepting online orders for NWWV as I've had to phone them in myself. Apropos NWWM, I don't know as I never tried it.
Every bozo I've spoken with at Ameritrade doesn't know (or won't say) what MM they use...they just state that they use "whatever center executes orders the fastest given the current market conditions".
