CFTC Specs Z

What it is

CFTC Specs Z — registry key cot_specs_z.

Positioning extremes are contrarian setup signals, not direction indicators. Used by squeeze_setup composite + transitions; not in health score.

Source

Source module: cot
Data source: back_fillable

Fetched directly from app/sources/cot.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

52-week Z-score of cot_specs_net (S&P 500 e-mini speculator net positioning): (specs_net_today − mean_52w) / stdev_52w. Flags spec positioning extremes; one of the squeeze_setup triggers when ≤ −1.5. See app/sources/cot.py:117.

Where it surfaces

• API field: positioning.cot.specs_z on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)
• Surface: /signals/sparklines (UI sparklines)
• Sparkline aliases: cot_z

Bands / thresholds

Classifier direction: range_is_better.

Health-score / alignment role

Display-only — has bands for surface labeling but does not contribute to the health score (scoring is handled by a companion metric).
