How it traded
Intraday run. It opened up 1.1% at 0.9500, then ran from the open to the high of 1.72 in 175 minutes through a halt.
| Time (ET) | What happened | Watch it |
|---|---|---|
| 4:01 a.m. | Pre-market high, 0.9887 | |
| 9:30 a.m. | The open: 0.9500, up 1.1% from the previous close | |
| 12:00 p.m. | First trade 20% above the previous close of 0.9400 | |
| 12:04 p.m. | Halted: LULD pause (limit up-limit down). Trading resumes at 12:09 p.m. | |
| 12:13 p.m. | Volume since 4:00 a.m. passes the whole float, 4.01 million shares | |
| 12:25 p.m. | High of the day to the close, 1.72 | |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 1.44, 16.3% 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.
