Founding Subscriber · first ten

€129 is the founding rate. As the publication proves out and the price rises with it, the first ten subscribers keep €129 for as long as Quorum Index operates. Founding subscribers also get a direct line to shape what gets built next.

No code to enter. Subscribe to Pro below and your rate is held. “For life” means for as long as Quorum Index operates as a business: a price you keep, not a guarantee the service runs forever. When the ten are taken, this offer comes down.

Common questions.

Is this trading advice? No. Quorum Index publishes structural observations on public markets: patterns in volatility, trend strength, momentum. It does not tell you what to buy or sell. Subscribers use the observations as one input among many.

What if it isn’t right? Every observation is graded against what the market printed in the twenty-four hours that followed. The graded record is public and served live, no account needed: total observations graded, structural move detection, and directional accuracy. Directional accuracy sits close to even, and we say so plainly: Quorum Index detects where structure is moving, it does not call which way. Structural move detection runs near ninety percent. We publish no expected-value or realized-edge figure, because the honest realized number is not one worth selling on. The record does not hide losses.

What’s the difference between Pro and Pro+ today? Pro gives you the full publication: every observation, the dashboard, the audit ledger. Pro+ adds first access to a forthcoming series of institutional briefings (Q3 2026) and priority support. If institutional briefings are not on your roadmap, Pro is the complete product.

What is a Founding Subscriber? €129 is the founding rate, and it is set to rise as the publication proves out. The first ten subscribers keep €129 for as long as Quorum Index operates, even after the standard price goes up, and get a direct line to shape the roadmap. There is no code to enter: subscribe to Pro and the rate is held. “For life” means for as long as the business operates. It is a rate you keep, not a promise the service runs forever. When the ten places are taken, the offer comes down.

Can I cancel? Any time, through the Stripe customer portal. The link is in your receipt email. No cancellation fee.
