Range structures and their resolution: opening range, breaks, consolidation, pullbacks, reversals, unusual range width.

Query it

Every applicable form factor, grouped by endpoint family. Swap YOUR_KEY for the value from /dashboard/keys. Response payloads are real captures, sampled 2026-08-18 and trimmed — your run's values and dates will differ.

Use signals /v2/signals/{signal}

One signal across the market: who matches now, who matched then, and a push when someone starts. Docs →

Live — every ticker where it fires now
curl "https://api.tickerbot.io/v2/signals/narrow_hourly_range" \
  -H "Authorization: Bearer YOUR_KEY"
Response (sampled 2026-08-18, trimmed)
{
 "as_of": "2026-08-18T00:24:45.582Z",

 "condition": null,

  }
 ]
}
Subscribe — webhook when a ticker starts matching
curl -X POST "https://api.tickerbot.io/v2/signals/narrow_hourly_range/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"target_url": "https://example.com/hooks/tickerbot"}'

Returns 201 with the created webhook — the same shape as GET /v2/webhooks/{id}, plus a one-time signing_secret for HMAC verification.

Use scan /v2/scan

The whole market through a WHERE clause — this signal composed freely with any other column. Docs →

Live — the whole market, filtered on this signal
curl -G "https://api.tickerbot.io/v2/scan" \
  --data-urlencode "q=narrow_hourly_range" \

Subscribe — webhook on a market-wide condition
curl -X POST "https://api.tickerbot.io/v2/scan/subscribe" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_KEY" \
  -d '{"q": "narrow_hourly_range", "target_url": "https://example.com/hooks/tickerbot"}'

Returns 201 with the created webhook object; deliveries carry the tickers matching the condition at each evaluation.

Use events /v2/events

The flag as a timeline: each edge as a point event, and the spans it stayed true. Docs →

Firings — every enter edge as a point event
curl -G "https://api.tickerbot.io/v2/events" \
  -d "kind=signal" -d "signal=narrow_hourly_range" -d "transition=enter" -d "since=2026-01-10" \

Spans — when it was true for one ticker (TEC)
curl "https://api.tickerbot.io/v2/signals/narrow_hourly_range/TEC/events" \
  -H "Authorization: Bearer YOUR_KEY"

}

Same grammar on scan and webhooks. This column is live-tense only — it isn't historized, so ?asof= reads and series pulls don't carry it.
