I'm sure scottrade and etrade let you. They have a lot 'looser' restrictions than some others. TD Ameritrade has it as a DTC chill and will not allow you to buy. Every stock I've seen with DTC chill has continued to go down, even if it bounces for a day or two, it will continue down. I used to get mad about it because I would miss bounces, but I realized it has saved me just as many times, plus more.
Cheers to making money though! I hope for your sake it bounces hard!
Trade how you want, but you can never lose with freebies!
