Dalam artikel sebelumnya, kami merancang strategi pemantauan penyebaran kontrak multi-spesies 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 programmatic cryptocurrency dan perdagangan kuantitatif. Saya berharap bahwa pemula dapat mengumpulkan pengalaman yang berharga.
Peringatan spoiler, strategi berjalan, dan aku sedikit bersemangat!
Desain keseluruhan strategi diterapkan dengan cara yang paling sederhana. Meskipun detailnya tidak terlalu menuntut, Anda masih dapat mempelajari beberapa tips dari kode. Kode strategi keseluruhan kurang dari 400 baris, sehingga tidak akan membosankan untuk dibaca dan dipahami. Tentu saja, ini hanya DEMO uji coba, butuh waktu untuk mengujinya. Jadi yang ingin saya katakan adalah: strategi saat ini hanya berhasil dalam membuka posisi, dan berbagai situasi seperti menutup posisi perlu diuji dan diverifikasi. Bug dalam desain program tidak dapat dihindari, jadi pengujian dan DEBUG sangat penting!
Kembali ke desain strategi, berdasarkan kode dalam artikel sebelumnya, strategi ditambahkan:
Di atas adalah fungsi tambahan. Untuk menyederhanakan desain, strategi hanya dirancang untuk lindung nilai positif (kontrak jangka pendek jangka panjang, kontrak jangka pendek jangka panjang). Saat ini, kontrak abadi (dekat jangka) memiliki tingkat biaya negatif, yang hanya dapat lama untuk kontrak abadi untuk melihat apakah dapat meningkatkan keuntungan tingkat.
Biarkan strategi berjalan untuk sementara waktu ~
Setelah pengujian selama sekitar 3 hari, fluktuasi penyebaran masih mungkin.
Di sini kita bisa melihat keuntungan dari beberapa tingkat pendanaan.

Pidato umum strategi:https://www.fmz.com/strategy/288559
Strategi ini menggunakan perpustakaan kelas template yang ditulis oleh saya sendiri, yang tidak umum karena tidak terlalu baik.
Jika Anda tertarik, Anda dapat menggunakan OKEX V5 simulasi bot untuk menguji. Oh, omong-omong, strategi ini tidak bisa diuji kembali~
