   * Submits a Limit Order to be executed on the Gateio Exchange for the desired market defined by

   * actually gets created. The reason for this is that orders are simply submitted to a queue in
   * their 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.
   *
   * @return String "true"/"false" Used to determine if the order request was submitted
