I picked up some WAMUQ in my Zecco account yesterday. I use them to place market orders, since I have wondered in the past how effective they are when placing orders on the bid.
Zecco is all right, but nothing to write home about. Their "trading platform" is pretty marginal, but you can't hardly beat the 4.50 x trade trading fee. 10 free trades if account over $2,500. Business hours only for customer service.
TD Ameritrade at $9.99 x trade seems to offer the best of all worlds. Nice trading platform, 24/7 customer service. Good luck.
GLTA !!
