If you're eligible for Trade Central you'll be able to buy unlimited shares at $9.95 at TDW, BUT they're merging with Ameritrade in some months. I'm moving my TDW acct to OptionsXpress because I don't want to add to my Ameritrade account. Already sent an ACAT to get out of TDW, though I've used them since 1997 or 1998 and I liked them.
