Submits a new order to Paradex. 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).

Submits a new order to Paradex.

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).
