| Time (ET) | What happened |
|---|---|
| 4:12 a.m. | Pre-market high, 2.78 |
| 8:00 a.m. | News (Accesswire): Valion Appoints Life Sciences Veteran Dean Zikria as Interim CEO and Announces Board Leadership Transitions |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 2.75, 16.6% below the high |
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.
