Gunakan spot exchange objek dan memanggilexchange.GetTickers()fungsi dalam sistem backtest. Sebelum memanggil fungsi pasar manapun, GetTickers hanya mengembalikan data ticker dari pasangan perdagangan default saat ini. Setelah memanggil fungsi pasar, ia mengembalikan data ticker dari semua varietas yang diminta. Anda dapat merujuk pada contoh uji berikut:

• Fungsi ini meminta pertukaran untuk agregat ticker antarmuka, tidak perlu mengatur pasangan perdagangan, kode kontrak sebelum panggilan.
• Sistem backtesting mendukung fungsi ini.
• Objek Exchange yang tidak menyediakan antarmuka ticker agregat tidak mendukung fungsi ini.
• Fungsi ini tidak mendukung kontrak opsi.
