No 400-row chain. NVDA above $190 → profit. Below → lose the premium. That is the whole contract, and it fits on a card.
Every position settles against Robinhood Stock Token pricing and oracles. Strike, expiry and payoff are computed by the protocol, not a broker.
Stock Tokens are marketed as always-on programmable assets. 190+ tokens, including NVIDIA, Apple, Google and QQQ. Derivatives should never close either.
