Gulf-based traders own one of the cleanest US-equity time zones. 17:30 Dubai = NYSE open. Sector-Gate ORB waits for QQQ + SMH above VWAP at 10:15 NY. Current 20-day data: 34% baseline hit rate; the filter screens out 25% of marginal trades without sacrificing rate. Selectivity, not magic.

Basket Impact Ratio — single-name divergence from sector ETF predicts next-day return non-linearly. NVDA/AMD/AVGO vs SMH and META/AAPL vs XLK show mild lead (+1 to +3%) prints +0.15% next-day median; strong lead (>+3%) only +0.03% — exhausted.
