Crash Setup Detected

Alert ID: CRASH_SETUP
Category: composite
Cross-detection: no

Severity

CRITICAL — immediate attention; extreme stress or crash setup

Trigger condition

{
  "type": "and",
  "conditions": [
    {
      "field": "gex",
      "op": "lt",
      "value": -1.5
    },
    {
      "field": "hy_oas",
      "op": "gt",
      "value": 4.0
    },
    {
      "field": "pct_above_50sma",
      "op": "lt",
      "value": 30
    }
  ]
}

All of the following must hold:

• gex < -1.5
• hy_oas > 4.0
• pct_above_50sma < 30

Message template

CRASH SETUP: deeply negative GEX ({gex:.1f}B), credit stress (HY OAS {hy_oas:.2f}%), breadth collapse ({pct_above_50sma:.0f}%).

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: none. Re-evaluation on every cycle.
• 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 (critical-tier).
• alert_escalated webhook (critical-only).
• alert_resolved webhook when the condition clears (non-cross-detection alerts only).
