Abnormal same-day volume at an OTM strike, confirmed the next day by a
large open-interest increase — a real position, not day-trade churn.
Put-side walls below spot flag downside ("dip") risk; call-side walls
above spot flag upside ("raise") risk. See
engine/otm_wall.py for detection logic and
web/data/otm_wall_criteria.json for tunable thresholds.
