Sebagai orang yang sedang tumbuh dewasa, saya bingung dengan pilihan arah dalam perdagangan berjangka platform dan kombinasi instruksi jual beli.

SetDirection ((buy/sell/closebuy/closesell), ada empat jenis set
Kemudian, panggil fungsi exchange.Buy/Sell () untuk melakukan order.

Setelah terjerat dalam beberapa kombinasi:
Cara membeli dan menjual
buy dan sell di arah
closebuy buy dan sell
Bagaimana cara memahami buy dan sell dalam arah closesell, setelah diuji secara manual dengan metode closesell, adalah sebagai berikut:
Saya menyimpulkan bahwa:
<unk>// Kesimpulan 1: Apakah arah saat ini adalah buy atau sell, membuka lebih banyak posisi adalah buy, membuka posisi kosong adalah sell<unk>
Yang kedua, apakah itu closebuy atau closesell, biasanya itu adalah sell, dan yang kosong adalah buy.

Untuk referensi masakan yang lebih kecil. Kode masakan yang diuji adalah sebagai berikut:
