How it traded
Intraday run. It opened up 4.1% at 14.52, then ran from the open to the high of 19.00 in 327 minutes.
| Time (ET) | What happened |
|---|---|
| 6:44 a.m. | Pre-market high, 14.25 |
| 9:30 a.m. | The open: 14.52, up 4.1% from the previous close |
| 1:56 p.m. | First trade 20% above the previous close of 13.95 |
| 2:57 p.m. | High of the day to the close, 19.00 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 16.54, 12.9% 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.
