Saya melihat contoh untuk mendapatkan array dari Record melalui exchange.GetRecords ((Period)). Tapi saya ingin mendapatkan array dengan harga, seperti open array dari 20 baris terakhir K, close array dari 20 baris terakhir K, dan kemudian melakukan beberapa perhitungan dengan numpy pada array ini, bagaimana cara melakukannya?

import talib
def main():
    records = exchange.GetRecords()
    cci = talib.CCI(records.High, records.Low, records.Close, 14)   # 14 这个参数 可以 缺省。
    Log(cci)
