stever,
I recently purchased shares of PTSC and was not required to make a call in order. It was actually 2 buy orders within the last 2 weeks and both were executed electronically.
I've attempted to purchase other BB stocks before and have received notice that that particular stock could only be traded by calling in.
For me, this is a first for trading PTSC.
IMO, this is temporary and normal electronic trading for PTSC will resume when the dust settles.
Regards,
PxP
