| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | Pre-market high, 0.8600 |
| 9:30 a.m. | The open: 0.7940, down 4.0% from the previous close |
| 12:30 p.m. | High of the day to the close, 0.9097 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 0.8923, 1.9% below the high |
| 4:19 p.m. | First trade 20% above the previous close of 0.8270 |
| 4:30 p.m. | Volume since 4:00 a.m. passes the whole float, 2.74 million shares |
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.
