How it traded

Gap, run and fade. It gapped up 11.2% to 5.10 at the open, ran from the open to the high of 7.15 in 82 minutes through a halt, then gave back 56% of that move by 4:00 p.m., trading at 6.01.

The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.
