Copper/Gold RoC

What it is

Copper/Gold RoC — registry key copper_gold.

Classifier metric. See the bands table below for the band-by-band reading.

Source

Source module: macro_indicators
Data source: computed

Derived metric — produced inside the platform (app/sources/macro_indicators.py or equivalent) rather than fetched as a raw upstream value. See the How it's computed section below for the formula.

How it’s computed

Alias of copper_gold_ratio surfaced under a shorter API key.

Where it surfaces

• API field: signals.copper_gold_20d_roc on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)
• Surface: /signals/history time series
• Surface: /signals/sparklines (UI sparklines)

Bands / thresholds

Classifier direction: higher_is_better.

Health-score / alignment role

• Health score component: copper_gold (weight + math in app/signals/config/score_weights.json and app/signals/score.py).
• Alignment category: growth_expectations, default weight 1.5 (see /kb/alignment for the 11-category framework).
• Contributes to: health_score.Copper/Gold, implication.growth_expectations, alignment.growth_expectations

Release cadence

• Publishes: intraday
