hopefully that is just a Scottrade thing temporarily and not a DTCC thing, which would hit all major brokers who clear through them.
I'm in another stock that the DTCC put a lock on last July and is still locked. really stinks the control they have and don't have to answer to anyone. But the other stock was locked after a couple of days where the volume exceeded the entire float, so there's bound to be a LOT of NSS there.
this volume has been quite reasonable though in comparison
