Bắt đầu với hàm create_cross_order và yêu cầu POST của hàm này tới /fapi/v1/order, sau đó đối chiếu các tham số được cung cấp với tài liệu Binance Futures API. Issue không nêu tệp nào trong repository hoặc test nào, vì vậy để hoàn thành cần tái hiện lỗi đã được báo cáo và xác nhận rằng order cùng hành vi TP/SL của order được chấp nhận như dự kiến.
