| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | First trade 20% above the previous close of 1.32 |
| 4:01 a.m. | Volume since 4:00 a.m. passes the whole float, 78,511 shares |
| 4:05 a.m. | Pre-market high, 2.67 |
| 4:05 a.m. | High of the day to the close, 2.67 |
| 9:30 a.m. | The open: 2.11, up 59.8% from the previous close |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 1.95, 27.0% 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.
