Le téléchargement de plusieurs stocks à la fois à partir de yahoo finance python

Vous pouvez utiliser la nouvelle Python YahooFinancials module avec des pandas pour ce faire. YahooFinancials est bien construit et reçoit des données par le hachage de la banque de données de l'objet présent dans chaque Yahoo Finance page Web, de sorte qu'il est rapide et ne pas compter sur l'ancien abandonnées api ni un web pilote comme un grattoir. Les données sont renvoyées sous forme de JSON et vous pouvez tirer autant de stocks que vous voulez à la fois par le passage d'une liste de stock/index tickers pour initialiser le YahooFinancials Classe.

$ pip install yahoofinancials

Exemple D'Utilisation:

from yahoofinancials import YahooFinancials
import pandas as pd
# Select Tickers and stock history dates
ticker = 'AAPL'
ticker2 = 'MSFT'
ticker3 = 'INTC'
index = '^NDX'
freq = 'daily'
start_date = '2012-10-01'
end_date = '2017-10-01'
# Function to clean data extracts
def clean_stock_data(stock_data_list):
new_list = []
for rec in stock_data_list:
if 'type' not in rec.keys():
new_list.append(rec)
return new_list
# Construct yahoo financials objects for data extraction
aapl_financials = YahooFinancials(ticker)
mfst_financials = YahooFinancials(ticker2)
intl_financials = YahooFinancials(ticker3)
index_financials = YahooFinancials(index)
# Clean returned stock history data and remove dividend events from price history
daily_aapl_data = clean_stock_data(aapl_financials
.get_historical_stock_data(start_date, end_date, freq)[ticker]['prices'])
daily_msft_data = clean_stock_data(mfst_financials
.get_historical_stock_data(start_date, end_date, freq)[ticker2]['prices'])
daily_intl_data = clean_stock_data(intl_financials
.get_historical_stock_data(start_date, end_date, freq)[ticker3]['prices'])
daily_index_data = index_financials.get_historical_stock_data(start_date, end_date, freq)[index]['prices']
stock_hist_data_list = [{'NDX': daily_index_data}, {'AAPL': daily_aapl_data}, {'MSFT': daily_msft_data},
{'INTL': daily_intl_data}]
# Function to construct data frame based on a stock and it's market index
def build_data_frame(data_list1, data_list2, data_list3, data_list4):
data_dict = {}
i = 0
for list_item in data_list2:
if 'type' not in list_item.keys():
data_dict.update({list_item['formatted_date']: {'NDX': data_list1[i]['close'], 'AAPL': list_item['close'],
'MSFT': data_list3[i]['close'],
'INTL': data_list4[i]['close']}})
i += 1
tseries = pd.to_datetime(list(data_dict.keys()))
df = pd.DataFrame(data=list(data_dict.values()), index=tseries,
columns=['NDX', 'AAPL', 'MSFT', 'INTL']).sort_index()
return df

Plusieurs stocks de données à la fois exemple (retourne la liste des objets JSON pour chaque téléscripteur):

from yahoofinancials import YahooFinancials
tech_stocks = ['AAPL', 'MSFT', 'INTC']
bank_stocks = ['WFC', 'BAC', 'C']
yahoo_financials_tech = YahooFinancials(tech_stocks)
yahoo_financials_banks = YahooFinancials(bank_stocks)
tech_cash_flow_data_an = yahoo_financials_tech.get_financial_stmts('annual', 'cash')
bank_cash_flow_data_an = yahoo_financials_banks.get_financial_stmts('annual', 'cash')
banks_net_ebit = yahoo_financials_banks.get_ebit()
tech_stock_price_data = tech_cash_flow_data.get_stock_price_data()
daily_bank_stock_prices = yahoo_financials_banks.get_historical_stock_data('2008-09-15', '2017-09-15', 'daily')

Sortie JSON Exemple:

Code:

yahoo_financials = YahooFinancials('WFC')
print(yahoo_financials.get_historical_stock_data("2017-09-10", "2017-10-10", "monthly"))
