Plans & pricing
A plan for the book
you actually run.
Arcane bills on the scale of what you're watching. A retail observer tracking three assets and an institutional desk running risk on a thousand both get the same regime engine — the differences are in coverage, delivery, and what the support line costs when you need it at 04:30 ET.
Annual billing saves two months on every tier. Every plan above Observer includes the full VIDI v8.4 regime model, all briefings, and access to the Build API within your quota. No trial surcharge; you pay only for what you use above plan.

Frequently asked
Things we're often asked.
If your question isn't here, reach support or talk to sales. We respond during market hours and have a global on-call for institutional accounts.
Can I try Arcane before I pay?
Observer is free forever and includes the full regime engine on 3 assets with a 24-hour signal delay — enough to decide whether the reasoning matches your own. Pro comes with a 14-day full-feature trial on your first subscription, billed only if you keep the seat.
How does annual billing save two months?
Annual plans are priced at 10× the monthly rate instead of 12×. On Pro, that's $2,800 annual vs $3,360 monthly — a $560 difference you get back in coverage or keep.
What happens if I exceed my API quota?
Calls past your included quota are billed at $0.002 per request (Pro), $0.0012 (Desk), or contract-negotiated (Institutional). We never rate-limit you into failure; overages just show up on the next invoice. You can set a hard cap in Build settings.
Can I move up or down a tier mid-billing?
Upgrades take effect immediately and are pro-rated; you're charged the difference on the next invoice. Downgrades take effect at the end of the current billing period. Seats on Desk can be added mid-cycle at the same pro-rated rule.
Do you offer education, non-profit, or journalist pricing?
Yes. Full Pro features at 40% off for accredited academic researchers, verified non-profit analysts, and working financial journalists. Apply through support.
What data does Arcane store about my trading?
Arcane doesn't receive, store, or process your trade data. The engine trains on public market microstructure — not on your book, orders, or holdings. Your watchlist and preferences are stored encrypted at rest and are not shared with any other tenant. See our Privacy Notice.
Is Arcane regulated or licensed?
Arcane is a research and intelligence service, not a registered investment adviser, broker-dealer, or FCMP. Nothing published is investment advice. Institutional customers receive a full disclosure pack as part of the MSA.
How do I cancel?
Pro and Desk cancel from Your Arcane · Plan & billing any time. Institutional cancels per contract. No cancellation fees. No retention call. We ask for the reason; you're not required to answer.
