How it traded
Intraday run. It opened up 1.3% at 14.20, then ran from the open to the high of 20.85 in 372 minutes.
| Time (ET) | What happened |
|---|---|
| 9:30 a.m. | The open: 14.20, up 1.3% from the previous close |
| 2:25 p.m. | First trade 20% above the previous close of 14.02 |
| 3:42 p.m. | High of the day to the close, 20.85 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 18.70, 10.3% 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.
