How it traded
Intraday run. It opened down 0.1% at 13.80, then ran from the open to the high of 16.43 in 373 minutes.
| Time (ET) | What happened |
|---|---|
| 5:24 a.m. | Pre-market high, 13.82 |
| 9:30 a.m. | The open: 13.80, down 0.1% from the previous close |
| 3:43 p.m. | High of the day to the close, 16.43 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 15.04, 8.5% 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.
