FORM 8-K
How it traded
| Time (ET) | What happened |
|---|---|
| 6:30 a.m. | SEC filing 8-K: FORM 8-K |
| 6:44 a.m. | First trade 20% above the previous close of 10.90 |
| 6:44 a.m. | Pre-market high, 13.14 |
| 6:44 a.m. | High of the day to the close, 13.14 |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 11.77, 10.4% 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.
