TD would not do one of the stocks I was going to get into so I called them and they said something along the lines that some of these stocks involved paper trading and if they could not do it all electronically they would not trade it. I then opened up an Etrade account and they have traded all of these types for me. I bought Kmag yesterday thru etrade and the trade went thru in just minutes. Almost as fast as a normal trade.
