Returns an order status object with a unique order `id` assigned by Paradex. This order `id` serves as the primary identifier for the order. The REST API performs basic validation and queues the order for risk checks (order `status`=`NEW`). Once validation and risk checks are successful, the order is sent to the matching engine. The matching engine processes the order and updates the status to `OPEN` if the order is resting. If the order is fully filled or cannot be processed, the status changes to `CLOSED` and a `cancel_reason` code is provided (e.g., fully filled or no liquidity).
