Import strategy artifact (JSON)
Artifacts with short legs are rejected — Robinhood is long-only US spot. Activation to paper is a separate step; nothing trades automatically on import.
Billing — service credits
Each paper order costs 1 credit. New accounts get 25 free. Passes are paid via AllScale hosted checkout (USDC/USDT, card on-ramp available). Purchases are non-refundable service credits — separate money from any trading funds.
Checkout opens on AllScale's hosted page (a white page saying "The Beast" is still us — shared merchant store). Credits land automatically when payment confirms.
