試圖從幾種資產的 MT5 中獲取歷史數據

Question

我正在學習 python。 我試圖從 MT5 獲取多只股票的歷史數據，但是股票的 arrays 有不同的長度，我不知道如何解決它。

錯誤：ValueError：值的長度（71）與索引的長度（100）不匹配

if not mt5.initialize():
    print("initialize() failed, error code =", mt5.last_error())
    quit()


s = Service(ChromeDriverManager().install())
wd = webdriver.Chrome(service=s)

wd.get("https://sistemaswebb3-listados.b3.com.br/indexPage/day/IBRA?language=pt-br")
sleep(3)
wd.find_element(By.ID,"segment").send_keys("Setor de Atuação")
sleep(3)
wd.find_element(By.PARTIAL_LINK_TEXT,"Download").click()
sleep(3)


list_of_files = glob.glob("C:/Users/xxxxx/Downloads/*") # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getctime)


lista= pd.read_csv(latest_file, sep=';', encoding='ISO-8859-1',skiprows = 0, skipfooter=2, engine='python', thousands='.',decimal=',', header=1, index_col=False)
ativos = pd.DataFrame(lista)

lista = ativos['Código']
df = pd.DataFrame()
for i in lista:
    barras = mt5.copy_rates_from(i, mt5.TIMEFRAME_D1, datetime.today(), 100)
    df[i] = barras['close']

print(df)

Answer 1

我可以這樣解決：

for i in lista:
    barras = mt5.copy_rates_from(i, mt5.TIMEFRAME_D1, datetime.today(), 100)
    df[i] = pd.Series([y['close'] for y in barras])
    df[i]= df[i].fillna(0)
