| Time (ET) | What happened |
|---|---|
| 8:00 a.m. | News (Business Wire): bioAffinity Technologies Regains Compliance with Nasdaq Listing Requirements |
| 8:02 a.m. | First trade 20% above the previous close of 8.93 |
| 8:18 a.m. | Pre-market high, 11.44 |
| 8:30 a.m. | Volume since 4:00 a.m. passes the whole float, 1.16 million shares |
| 9:30 a.m. | The open: 10.90, up 22.1% from the previous close |
| 9:41 a.m. | High of the day to the close, 12.30 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 10.62, 13.7% 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.
