Physical Market Intelligence
Shanghai 4074.49/oz vs Western 4109.78/oz · premium unavailable (timing not session-aligned)
East–West premium is withheld because Western/FX observations are not session-aligned with the SGE comparison timestamp (calendar-day matches and daily bars are insufficient). Alignment: Calendar-day unmatched (Timing quality insufficient for a confident premium. Target 2026-07-31T07:30:00.000Z; Western 2026-07-31T00:00:00.000Z; FX 2026-07-31T00:00:00.000Z.) Shanghai reference is official SGE Daily Report contract Au99.99. Canonical East–West methodology (EAST-WEST-GOLD-2.1): session-close comparison using Au99.99 Closing Price (CNY/g) with Western XAU/USD and USD/CNY taken from intraday bars nearest the SGE session-end comparison timestamp (default 15:30 China Standard Time = 07:30 UTC). Weighted Average Price is not compared to a single unrelated Western point for the headline premium; it is reserved for optional session-window-average analysis. Settlement is never used. SHAU benchmark, Au(T+D), Au99.95, and SHFE futures are never substituted. USD/oz = (CNY/g × 31.1034768) / (CNY per USD). Premium = Shanghai USD/oz − Western XAU/USD. Public premiums require session-aligned (or session-window-average) intraday legs within MAX_PRICE_TIME_MISMATCH_MINUTES. Twelve Data 1day bars are calendar-day-unmatched / previous-close and do not publish a confident premium. Matching calendar dates alone never implies session equivalence.
