| Time (ET) | What happened |
|---|---|
| 8:16 a.m. | News (GlobeNewsWire): FDA Grants SeaStar Medical Breakthrough Device Designation for its SCD Therapy for the Treatment of Hyperinflammation in Adult Patients with Sepsis or a Septic Condition |
| 8:16 a.m. | Pre-market high, 3.80 |
| 8:16 a.m. | High of the day to the close, 3.80 |
| 9:30 a.m. | The open: 3.26, up 2.2% from the previous close |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 3.74, 1.6% 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.
