| Time (ET) | What happened |
|---|---|
| 7:00 a.m. | News (GlobeNewsWire): BioStem Technologies Secures Up to $40 Million in a Committed Equity Facility |
| 7:07 a.m. | Pre-market high, 4.54 |
| 9:30 a.m. | The open: 4.25, down 2.5% from the previous close |
| 12:43 p.m. | First trade 20% above the previous close of 4.36 |
| 12:46 p.m. | High of the day to the close, 5.35 |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 4.67, 12.6% 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.
