How to size Hyperliquid trades and set leverage so an agent stays inside its owner's caps by design rather than by bouncing off them: what the per-order and daily notional limits actually count, why every order sent costs its full size for the day whether or not it trades, why closing a position also consumes the budget, when to set leverage, and how to read liquidation distance. Use alongside hyperliquid-trading before deciding a size or a leverage. NOT a substitute for the caps themselves, which are enforced server-side.
