How it traded

| Time (ET) | What happened |
|---|---|
| 9:22 a.m. | First trade 20% above the previous close of 0.5853 |
| 9:23 a.m. | Pre-market high, 0.7081 |
| 9:30 a.m. | The open: 0.6490, up 10.9% from the previous close |
| 3:40 p.m. | High of the day to the close, 1.06 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 0.9814, 7.4% 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.
