| Time (ET) | What happened |
|---|---|
| 4:00 a.m. | Pre-market high, 1.70 |
| 9:30 a.m. | The open: 1.64, up 4.5% from the previous close |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 3.29, 15.9% 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.
