Comienza con la función create_cross_order y su solicitud POST a /fapi/v1/order; después, compara los parámetros proporcionados con la documentación de la Binance Futures API. El issue no indica ningún archivo del repositorio ni ninguna prueba, por lo que para darlo por terminado habría que reproducir el error reportado y confirmar que la orden y su comportamiento de TP/SL se aceptan según lo previsto.
