Dalam artikel yang lalu, kami merancang strategi pemantauan penyebaran kontrak multi-simbol bersama. Dalam artikel ini, kami akan terus meningkatkan idea ini. Mari kita lihat apakah idea itu layak, dan jalankan dengan bot simulasi OKEX V5 untuk mengesahkan reka bentuk strategi. Proses ini juga diperlukan untuk berpengalaman dalam proses perdagangan berprogram cryptocurrency dan perdagangan kuantitatif. Saya harap anda dapat mengumpulkan pengalaman yang berharga dari itu.
Spoiler: strategi telah berjalan, yang agak menarik.
Reka bentuk keseluruhan strategi dilaksanakan dengan idea yang paling mudah. Walaupun tidak ada keperluan yang ketat untuk pemprosesan butiran, anda masih boleh mempelajari beberapa trik dari kod. Seluruh strategi kurang dari 400 baris, jadi tidak terlalu membosankan untuk membacanya. Sudah tentu, ini hanya DEMO untuk ujian, dan kita perlu menjalankannya untuk sementara waktu untuk melihat hasilnya. Apa yang ingin saya katakan ialah: strategi semasa hanya berjaya dalam membuka kedudukan, dan terdapat pelbagai situasi, seperti kedudukan penutupan, yang sebenarnya diuji dan dikesan. Kecacatan dalam reka bentuk program tidak dapat dielakkan, jadi ujian dan debugging sangat penting!
Kembali ke reka bentuk strategi, berdasarkan kod dalam artikel lepas, saya telah menambah:
Yang di atas adalah fungsi yang ditambah. untuk menjadi mudah, strategi hanya direka lindung nilai positif (membuat pendek untuk kontrak jangka panjang; membuat panjang untuk kontrak jangka pendek). pada masa ini, kontrak kekal (jangka pendek) mempunyai kadar pembiayaan negatif; hanya membuat dalam kontrak kekal, untuk melihat sama ada pulangan kadar pembiayaan boleh meningkat.
Biarkan strategi berjalan untuk seketika.
Ia telah diuji selama kira-kira 3 hari, dan turun naik penyebaran sebenarnya baik-baik saja.
Sebahagian daripada pulangan daripada kadar pembiayaan dapat dilihat dalam gambar berikut.
Kod sumber strategi dikongsi seperti berikut:

Alamat Strategi:https://www.fmz.com/strategy/288559
Strategi menggunakan salah satu templat yang direka oleh saya sendiri; templat tidak cukup baik untuk ditunjukkan di sini, jadi anda boleh menggunakan templat lain dengan mengubah suai kod sumber strategi sedikit.
Jika anda berminat, anda boleh menjalankan strategi dalam OKEX V5 simulasi bot. Oh, betul, strategi tidak boleh diuji kembali!
