I have tried to use getrealtimeorders method to update the historical to live order when i start my strategy, but i’m still getting the error. am i doing something wrong here?

protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice,
                                  int quantity, int filled, double averageFillPrice,
                                  OrderState orderState, DateTime time, ErrorCode error,
                                  string comment)

            shortEntryOrder = GetRealtimeOrder(shortEntryOrder);

        if (pivotEntryOrder != null && pivotEntryOrder.IsBacktestOrder)
            pivotEntryOrder = GetRealtimeOrder(pivotEntryOrder);
    }
