Hi.
Was anyone able to get hourly information on stock prices, either individual or by S&P?

seems to have stopped working, now isnt returning anything - could be me of course

URL is http://www.google.com/finance/getprices?i=60&p=1d&f=d,o,h,l,c,v&df=cpct&q=VOD&x=LON
Empty DataFrame
Columns: []
Index: []
done

when I run that URL in the browser, it thinks I'm a bot and shuts me down, any way around that please ?

ta

that url failed for me as well.

Works great, but is there a way to save this data to a CSV file?

data.to_csv('output.csv')

To sum up this string..
Step 1: Install python: https://www.python.org/downloads/
Step 2: Install panda: pip install panda
Step 3: Save this code:
'
import requests
import pandas as pd
import arrow
import datetime

def get_quote_data(symbol='SBIN.NS', data_range='1d', data_interval='1m'):
res = requests.get('https://query1.finance.yahoo.com/v8/finance/chart/{symbol}?range={data_range}&interval={data_interval}'.format(**locals()))
data = res.json()
body = data['chart']['result'][0]
dt = datetime.datetime
dt = pd.Series(map(lambda x: arrow.get(x).to('Asia/Calcutta').datetime.replace(tzinfo=None), body['timestamp']), name='Datetime')
df = pd.DataFrame(body['indicators']['quote'][0], index=dt)
dg = pd.DataFrame(body['timestamp'])

return df.loc[:, ('open', 'high', 'low', 'close', 'volume')]

data = get_quote_data('SBIN.NS', '5d', '1m')
data.dropna(inplace=True) #removing NaN rows
print(data)
data.to_csv('output.csv')
'
Step 4: Drag the saved python file to CMD and an output CSV will be saved.

what is the symbol for NIFTY50 data

what is the symbol for NIFTY50 data

Yahoo finance symbol for nifty 50 = '^NSEI'

df.columns = ['OPEN', 'HIGH','LOW','CLOSE','VOLUME']

return df

for s in symbol:
data = get_quote_data(s,'1d','1m')
data.to_csv(s.strip(".NS")+'.csv')

this is for multiple stock symbols
