Modify the price or quantity of an existing open order. At least one of replacePrice or replaceQty must be provided.

Note: For spot orders and certain perpetual order conditions, this operation is implemented as a cancel-and-replace. In those cases, the original order is cancelled and a new order is submitted atomically. The returned orderId is the identifier of the amended order.
