Dalam artikel sebelumnya, kami telah merancang strategi pemantauan spread kontrak multi-simbol bersama. Dalam artikel ini, kami akan terus meningkatkan ide ini. Mari kita lihat apakah ide ini layak, dan jalankan dengan bot simulasi OKEX V5 untuk memverifikasi desain strategi. Proses ini juga diperlukan untuk dialami dalam proses perdagangan terprogram cryptocurrency dan perdagangan kuantitatif. Saya harap Anda dapat mengumpulkan pengalaman berharga dari itu.
Spoiler: strategi telah berjalan, yang sedikit menarik.
Desain keseluruhan strategi dilaksanakan dengan ide yang paling sederhana. Meskipun tidak ada persyaratan ketat untuk pemrosesan detail, Anda masih dapat mempelajari beberapa trik dari kode. Seluruh strategi kurang dari 400 baris, jadi tidak terlalu membosankan untuk membacanya. Tentu saja, ini hanya DEMO untuk pengujian, dan kita perlu menjalankannya untuk sementara waktu untuk melihat hasilnya. Yang ingin saya katakan adalah: strategi saat ini hanya berhasil dalam membuka posisi, dan ada berbagai situasi, seperti posisi penutupan, yang benar-benar diuji dan terdeteksi. Bug dalam desain program tidak dapat dihindari, jadi pengujian dan debugging sangat penting!
Kembali ke desain strategi, berdasarkan kode dalam artikel sebelumnya, saya telah menambahkan:
Yang di atas adalah fungsi yang ditambahkan. Untuk menjadi sederhana, strategi hanya dirancang lindung nilai positif (membuat pendek untuk kontrak jangka panjang; membuat panjang untuk kontrak jangka pendek). Saat ini, kontrak abadi (jangka pendek) memiliki tingkat pendanaan negatif; hanya membuat dalam kontrak abadi, untuk melihat apakah pengembalian tingkat pendanaan dapat ditingkatkan.
Biarkan strategi berjalan untuk sementara waktu.
Itu telah diuji selama sekitar 3 hari, dan fluktuasi penyebaran sebenarnya baik-baik saja.
Bagian dari pengembalian dari tingkat pendanaan dapat dilihat pada gambar berikut.
Kode sumber strategi dibagi sebagai berikut:

Strategi menggunakan salah satu template yang dirancang oleh saya sendiri; template tidak cukup baik untuk ditampilkan di sini, jadi Anda dapat menggunakan template lain dengan memodifikasi kode sumber strategi sedikit.
Jika Anda tertarik, Anda dapat menjalankan strategi di OKEX V5 simulasi bot. Oh, benar, strategi tidak bisa diuji kembali!
