How we are paid

Sources of income, and what we do not accept

Indicator subscriptions: Subscribers pay USD 149 a year for the daily reading and same-day signals, a price set close to what the service costs to run. The founder acts on the signal with their own capital. The indicator’s rules and record stay public regardless.
Research services: Each engagement is scoped and billed on its own.
Not accepted: We take no money from brokers or exchanges, and run no advertising.
