|---|---|
| 6:30 a.m. | News (PRNewsWire): Aethlon Medical & North Immunology Announce Merger to Advance Novel IL-13 x IL-18 Bispecific Antibody for Atopic Dermatitis |
| 6:30 a.m. | First trade 20% above the previous close of 1.43 |

| 3:59 p.m. | Last trade before the 4:00 p.m. close, 6.76, 51.7% 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.
