I asked my broker last week if I had a couple sell orders in say at 2.00 PPS and this got halted or up graded to Nasdaq would my shares sell at the 2.00 or if it opened at the 3.00 or 4.00 per share and she told me that they would automatically sell at the PPS that it opened back up at. hope this helps a little and hope she was correct which I think she is.
