How it traded
| Time (ET) | What happened |
|---|---|
| 7:39 a.m. | First trade 20% above the previous close of 1.90 |

| 7:40 a.m. | High of the day to the close, 2.96 |

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.
