Methodology: Metals Comparative Signal

Objective

Provide a cross-metal relative-context signal spanning gold, silver, copper, and lithium to identify comparative momentum, relative valuation pressure, and positioning-adjusted context.

Input Sources

• Metal price histories from configured market data sources.
• Derived comparative features across precious and industrial metals.
• Stored history state used for change-aware report updates.

Transformation Logic

• Standardise input series and align on comparable date windows.
• Compute relative-strength and z-score style comparative layers.
• Blend trend/momentum and macro-adjusted comparative components into a structured dashboard frame.
• Generate chart, table, and Gemini narrative summary; publish to signal history.

Output Interpretation

• Signal is contextual and comparative, not a stand-alone directional forecast.
• Stronger comparative readings indicate relative support versus peer metals.
• Use alongside asset-specific signals to avoid over-reliance on cross-sectional effects.

Limitations

• Relative signals can diverge from absolute performance during regime breaks.
• Different metal microstructures reduce direct one-to-one comparability.
• Short-term dislocations may reflect noise rather than persistent regime change.

Downstream Consumers

• Silver Market Analyst consumes this signal as metals_comparative_signal for cross-metal context.
• Signal report and history consumers use this for comparative diagnostics and auditability.
