Untuk masa yang lama, niaga hadapan dan lindung nilai spot biasanya direka untuk mengesan spread harga, dan mengambil pesanan untuk lindung nilai apabila spread harga dipenuhi.
Dalam pasaran yang berlainan dengan jenis subjek yang sama, peluang untuk lindung nilai timbul apabila terdapat perbezaan besar antara pesanan beli dan jual di antara kedua-dua pasaran. Secara amnya, kita akan mengambil pesanan yang menunggu yang memenuhi spread harga dan kemudian memegang kedudukan lindung nilai. Oleh itu, terdapat dua tujuan lindung nilai. Yang pertama adalah untuk lindung nilai terhadap kedudukan pesanan, dan yang kedua adalah untuk memastikan bahawa harga harga antara pembelian dan penjualan memenuhi jangkaan maksimum kita. Kelebihan perdagangan pesanan menunggu dalam hal ini adalah bahawa yurannya lebih rendah. Kelemahannya adalah bahawa tidak mudah untuk melaksanakan pesanan, dan lebih mudah untuk melaksanakan pesanan satu kedudukan.
Kemudian, kita merancang idea dagangan yang menunggu pesanan dibeli dalam buku pesanan beli pasaran A, dan menunggu pesanan dijual dalam buku pesanan jual pasaran B, dan kemudian mengesan akaun kami menunggu pesanan, dan meneruskan ke langkah seterusnya untuk pelaksanaan pesanan menunggu yang dikesan. Sebagai contoh, apabila perubahan pesanan menunggu dikesan, segera mengimbangi kedudukan lindung nilai semasa niaga hadapan dan spot. Untuk lebihan kedudukan niaga hadapan dan spot, buka beli atau tutup. Menurut peningkatan kedudukan lindung nilai, sesuaikan jarak antara pesanan menunggu seterusnya di pasaran dan tahap pertama pasaran, secara beransur-ansur lindung nilai untuk mendapatkan spread terbesar.

Dari statistik sistem backtest, akaun platform niaga hadapan kehilangan 0.01666 ETH, dan pertukaran spot menghasilkan keuntungan sebanyak 842.23758 USDT. Menurut harga spot ETH sebanyak 4252USDT pada akhir backtest, iaitu-0.01666 * 4252 = -70.83832000000001
Hasil ditambah keuntungan spot secara keseluruhan menguntungkan.
Walau bagaimanapun, ini hanya backtest, dan masalah yang lebih terperinci akan ditangani dalam bot sebenar.
