Untuk waktu yang lama, berjangka dan hedge spot umumnya dirancang untuk mendeteksi spread harga, dan mengambil pesanan untuk hedge ketika spread harga terpenuhi.
Berpikir tentang Pending Order Hedge
Dalam pasar yang berbeda dari jenis subjek yang sama atau yang sama, peluang untuk lindung nilai muncul ketika ada perbedaan besar antara pesanan beli dan jual antara kedua pasar. Secara umum, kita akan mengambil pesanan yang tertunda yang memenuhi spread harga dan kemudian memegang posisi lindung nilai. Oleh karena itu, ada dua tujuan lindung nilai. Yang pertama adalah untuk lindung nilai terhadap posisi order, dan yang kedua adalah untuk memastikan bahwa harga spread antara pembelian dan penjualan memenuhi harapan maksimum kita. Keuntungan dari perdagangan order tertunda dalam hal ini adalah bahwa biaya lebih rendah. Kelemahannya adalah tidak mudah untuk mengeksekusi pesanan, dan lebih mudah untuk mengeksekusi pesanan posisi tunggal.
Kemudian, kita mendesain ide trading yang menunggu order dibeli di buku order beli pasar A, dan menunggu order terjual di buku order jual pasar B, dan kemudian mendeteksi akun kami menunggu order, dan melanjutkan ke langkah berikutnya untuk eksekusi order menunggu yang terdeteksi. Misalnya, ketika perubahan order menunggu terdeteksi, segera menyeimbangkan posisi lindung nilai saat ini futures dan spot. Untuk kelebihan posisi futures dan spot, buka beli atau tutup. Menurut peningkatan posisi lindung nilai, sesuaikan jarak antara order menunggu berikutnya di pasar dan tingkat pertama pasar, secara bertahap lindung nilai untuk mendapatkan spread terbesar.

Analisis Backtest
Dari statistik sistem backtest, akun platform futures kehilangan 0,01666 ETH, dan bursa spot menghasilkan keuntungan sebesar 842.23758 USDT. Menurut harga spot ETH sebesar 4252USDT pada akhir backtest, yaitu-0.01666 * 4252 = -70.83832000000001Hasilnya ditambah keuntungan spot secara keseluruhan menguntungkan.
Namun, ini hanya backtest, dan masalah yang lebih rinci akan ditangani dalam bot nyata.
