How it traded
Intraday run. It opened down 0.3% at 3.60, then ran from the open to the high of 5.00 in 228 minutes through a halt.
| Time (ET) | What happened |
|---|---|
| 5:52 a.m. | Pre-market high, 3.76 |
| 9:30 a.m. | The open: 3.60, down 0.3% from the previous close |
| 12:58 p.m. | Halted: LULD pause (limit up-limit down). Trading resumes at 1:18 p.m. |
| 1:18 p.m. | First trade 20% above the previous close of 3.61 |
| 1:18 p.m. | High of the day to the close, 5.00 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 4.44, 11.2% 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.
