Leading Indicator Divergence

Alert ID: LEADING_DIVERGENCE
Category: alignment
Cross-detection: no

Severity

WARNING — conditions deteriorating; worth monitoring

Trigger condition

{
  "type": "computed",
  "computation": "leading_divergence"
}

Computed condition (leading_divergence) — the trigger logic lives in app/signals/alerts.py:_eval_computed. This alert does not decompose into a simple field threshold; consult the source for the exact semantics.

Message template

Leading indicator divergence: {leading_divergent_count}/7 leading signals disagree with SPY's {spy_5d_direction} trend — historically precedes repricing within 3-5 days.

Rendered with the current signals dict via Python str.format. Placeholders that fail to resolve fall back to the raw template (see _format_message in app/signals/alerts.py).

Cooldown / dedup

• Cooldown: 2880 minutes (~48.0 h) between fires. After the alert resolves, re-firing is suppressed until the cooldown window has passed.
• Dedup: at most one active (or acknowledged) row per alert_id at a time. Re-firing while active updates fired_at and the message but keeps the original first_fired_at.

Notifies

• Active alert feed (/api/v1/alerts/active, /alerts/summary).
• SSE stream (/api/v1/agents/stream) for real-time consumers.
• alert_fired webhook on first fire.
• alert_resolved webhook when the condition clears (non-cross-detection alerts only).
