European-open overnight drift persistence (02:00–03:00 ET)

The historically positive ES return from the exact 02:00 bar open through the 02:59 bar close persists after 2021, clears a 1-bp round-trip cost, remains positive at 3 bps, and localizes against three frozen paired adjacent hours. NQ is the frozen replication.
