Webhook Alerts for Financial Market Signals: Detect Narrative Shifts Before Terminals
Detect narrative shifts in markets before they show up on terminals. Set velocity thresholds for claims, tickers, and themes—then trigger webhook alerts into your research or risk workflow.
The Problem: Terminals Tell You What Happened — Not What’s Starting
Terminals are excellent at prices, flows, and news once confirmed. But many meaningful moves begin as a narrative shift: a phrase, claim, or framing that spreads faster than the underlying data.
If you’re in research, trading, IR, or risk, the edge is rarely “having more information.” It’s seeing what attention is converging on early enough to investigate.
What a “Narrative Shift” Looks Like (Operationally)
A narrative shift is measurable:
- Velocity: mentions/hour accelerates versus baseline
- Convergence: multiple accounts repeat the same claim wording
- Attribution drift: people cite “sources say” / “hearing” / “rumor” without primary links
- Topic binding: the claim gets attached to tickers, sectors, or macro themes
Signals Worth Alerting On (Finance Edition)
| Signal | What You Track | Why It Matters |
|---|---|---|
| Claim velocity | “guidance cut”, “probe”, “halt”, “recall”, “downgrade” | Claims spread before confirmation |
| Ticker + phrase binding | $TSLA + “deliveries miss” (example) | Markets move when narratives bind to symbols |
| Sector contagion | “regional banks” + “liquidity” | Narratives jump categories fast |
| Policy chatter | “emergency meeting”, “capital controls” | Macro risk often emerges as chatter first |
The Workflow: Detect → Verify → Escalate
1) Define a watchlist (small on purpose)
- Tickers you care about
- Key executives / regulators (public sources only)
- High-impact phrases (guidance, halt, recall, probe, downgrades)
2) Set thresholds like an on-call system
- Log: > 3× baseline
- Notify: > 10× baseline
- Act: > 25× baseline (open a ticket / incident / research task)
3) Deliver alerts as webhooks (so it becomes operational)
Send the alert into the system where work happens (Slack, Linear, Notion, internal tools).
TrendsAGI webhooks include an HMAC signature header (X-Webhook-Signature) so you can verify authenticity.
Risk Controls (So You Don’t Chase Noise)
- Require multi-source: alert only when more than one cluster forms
- Require persistence: trend stays elevated for N minutes
- Attach a runbook: “verify primary source → capture links → classify impact”
