Sebagai seorang yang sedang membesar, saya sangat bingung dengan pilihan arah dalam perdagangan niaga hadapan platform dan penggabungan arahan membeli dan menjual.

SetDirection ((buy/sell/closebuy/closesell), terdapat empat jenis set
Kemudian, panggil fungsi exchange.Buy/Sell () untuk membuat pesanan.

Ia boleh berlaku dalam beberapa keadaan:
<unk>Beli dan jual di arah buy
Buy dan sell dalam arah sell
closebuy buy dan sell
Bagaimana cara memahami buy dan sell dalam arah closesell, telah diuji secara manual dengan kaedah closesell.
Saya membuat kesimpulan ini:
<unk>// Kesimpulan 1: Sama ada arah semasa adalah buy atau sell, membuka lebih banyak kedudukan adalah buy, membuka kosong adalah sell <unk>
<unk>// Kesimpulannya: Sama ada dalam arah closebuy atau closesell, kebanyakan adalah sell, dan kosong adalah buy<unk>

Untuk rujukan yang lebih kecil, kod masakan yang diuji adalah seperti berikut:

function main() {
exchange.SetContractType("quarter")

exchange.SetDirection("sell")
var buy1 =exchange.GetTicker()
