| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | First trade 20% above the previous close of 4.48 |
| 4:37 a.m. | Pre-market high, 14.77 |
| 4:37 a.m. | High of the day to the close, 14.77 |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 4.91, 66.8% 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.
