| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | First trade 20% above the previous close of 2.17 |
| 4:00 a.m. | Pre-market high, 3.51 |
| 4:00 a.m. | High of the day to the close, 3.51 |

| 9:30 a.m. | The open: 2.92, up 34.6% from the previous close |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 2.48, 29.3% 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.
