   * back-end. One example for why an order might not get created is because there are insufficient funds. The best attempt you can make to confirm
   * that the order was created is to poll {@link #getOpenOrders}. However, if the order is created and executed before it is caught in its open state
   * from calling {@link #getOpenOrders} then the only way to confirm would be confirm the expected difference in funds available for your account.
