Spot price bands • Live across all spot markets on Lighter and Lighter on Robinhood Chain. Buy orders must be within −50% / +20% of the index price; sell orders within −20% / +50%. • Applies to new limit, market and TWAP orders. Market orders are checked against their worst acceptable price. Modified limit orders must stay within ±50%. SL/TP orders are excluded. • Orders outside these bands return error 21753: “order price is too far from the index price”. These checks cannot be disabled with price_protection.
