Strategi ini digunakan untuk mendapatkan dan memantau kadar pembiayaan dari pelbagai platform niaga hadapan seperti OKCoin, Binance, Bitget, dll. Ia mengundi pasaran kontrak kekal pelbagai bursa melalui benang selari, dan memperoleh data kadar pembiayaan, sambil menggunakan mekanisme kelewatan untuk mengoptimumkan kekerapan permintaan.
Artikel ini membuat beberapa perubahan kepada strategi untuk menyokong fungsi push penggera paparan dan kadar pembiayaan.
