Opening-gap size continuation (first-60-min drift)
ES sessions whose absolute same-contract overnight gap reaches the strictly prior 252-eligible-session 90th percentile continue in the gap direction from the 09:30 open through the 10:29 bar close after a 3-bp round-turn cost. NQ is a frozen cross-index replication.
