SHFE Silver Premium vs COMEX (USD/oz)This indicator measures the SHFE–COMEX silver premium/discount in USD per troy ounce.
SHFE silver is quoted in CNY per kilogram, so the script first converts SHFE:AG1! into USD/oz using the current USD/CNY exchange rate and the exact kg → troy oz factor (32.1507466). It then calculates:
Premium (USD/oz) = SHFE_USD/oz − COMEX_USD/oz
How to interpret:
Positive bars: SHFE is trading above COMEX (premium)
Negative bars: SHFE is trading below COMEX (discount)
Persistent regimes can reflect currency dynamics, regional liquidity, import/export constraints, and shifts in industrial demand.
How to use:
Add this indicator beneath the companion overlay indicator “SHFE Silver Price Discovery (USD/oz)” to keep the price chart readable while still visualizing divergence.
Watch for sustained premium expansions/contractions as inter-market confirmation signals, especially during volatile periods.
This indicator is intended for macro and inter-market analysis, not short-term scalping.
