Methodology: SLV ETF Flow Signal

Objective

Track SLV ETF holdings dynamics and infer flow pressure as a tactical positioning proxy for silver market interpretation.

Input Sources

• SLV holdings workbook and/or cached holdings CSV snapshots.
• Shares outstanding and NAV-per-share fields extracted from source files.
• Historical saved series for continuity and change tracking.

Transformation Logic

• Download and parse holdings source; fall back to cached artifacts if live retrieval fails.
• Build a time series of holdings changes and approximate flow pressure metrics.
• Classify current flow regime, generate chart + table, and produce summary via Gemini.
• Persist output to report HTML and global signal history.

Output Interpretation

• Positive flow pressure suggests supportive investor positioning context; negative pressure suggests distribution pressure.
• Signal is tactical and should be interpreted with macro and research context.
• Flow diagnostics are context inputs, not direct price forecasts.

Limitations

• ETF holdings are an imperfect proxy for broad silver demand.
• Corporate actions, reporting lags, or source formatting changes can distort short-term readings.
• Flow-pressure signals can reverse quickly in volatile markets.

Downstream Consumers

• Silver Market Analyst consumes this signal as slv_etf_flow_signal for tactical flow context.
• Signal history and report consumers use this for transparent flow diagnostics over time.
