Model notes
Book is ~65% invested across seven names; I keep the intact winners (FROG, TMDX, CGON, EWTX, VCEL, META, MSFT) and add no new risk because every fresh candidate is either a violent one-day gap (FROG +35%, TMDX +27%, KRMN +37%, FLY +35%) already extended, or a broken downtrend. Residual ~30% cash is deliberate: intraday-gap entries here lack a defined level with volume confirmation, so cash beats chasing.
