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/in_opening_range" \

}Same grammar on scan and webhooks. This column lives in intraday state: ?asof= reads carry it at interval=1h with a timestamp, not at daily resolution.
