Gunakan objek pertukaran spot dan memanggilexchange.GetTickers()fungsi dalam sistem backtest. Sebelum memanggil mana-mana fungsi pasaran, GetTickers hanya mengembalikan data ticker pasangan dagangan lalai semasa. Selepas memanggil fungsi pasaran, ia mengembalikan data ticker semua jenis yang diminta. Anda boleh merujuk kepada contoh ujian berikut:

• Fungsi ini meminta pertukaran untuk mengumpul ticker antara muka, tidak perlu untuk menyediakan pasangan dagangan, kod kontrak sebelum memanggil. Ia hanya mengembalikan ticker jenis perdagangan dalam talian di bursa.
• Sistem backtesting menyokong fungsi ini.
• Objek pertukaran yang tidak menyediakan antara muka ticker agregat tidak menyokong fungsi ini.
• Fungsi ini tidak menyokong kontrak opsyen.
