Intraday run. It opened up 1.6% at 8.83, then ran from the open to the high of 9.82 in 98 minutes.
| Time (ET) | What happened |
|---|---|
| 5:14 a.m. | Pre-market high, 9.18 |
| 9:30 a.m. | The open: 8.83, up 1.6% from the previous close |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 9.28, 5.5% 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.
