Alert rules

Build rules over probability, 24h move, volume, expiry, or UMA status. Active rules show on this page; firing rules surface as a banner on Home; the triggered-history list at the bottom records every past firing.

Alert rules and the firing history are stored locally in your browser. In-app banners on Home fire as soon as any rule is satisfied. Email delivery activates as soon as the email channel goes live — every existing rule keeps working without changes.

Power-user automation. When any of your alert rules fire in this browser, Orrery POSTs a stable JSON payload to every active endpoint below. Fully client-side — no server-side delivery yet, so an endpoint only fires while an Orrery tab is open. Use it for personal Zapier/n8n hooks, Discord webhook URLs, custom Lambda Function URLs.
