Hey everyone, I'm trying to run this code.
import os
import pickle
#import urllib2
from urllib.request import urlopen
#import cookielib
import http.cookiejar
import re
import time
import numpy as np
#import pylab as pl
# symbol - USDEUR=X - problem that the server sometimes returns 0.0
def getSpotPrice(symbol):
numberOfAttempts = 0
while numberOfAttempts < 10:
url =
'http://download.finance.yahoo.com/d/quotes.csv?s='+symbol+'&f=l1&e=.cs'
fxrate_pure = urllib2.urlopen(url).read()
fxrate = fxrate_pure.strip()
if fxrate != "0.00":
return fxrate
else:
numberOfAttempts += 1
time.sleep(1)
raise Exception("Unable to obtain market data from Yahoo! ... wrong
ticker???")
# symbol = the yahoo ticker; the expected tickers of the components contain
alphanumerical characters or dot or hyphen; if the yahoo format changes,
nothing is returned
def getConstituentsOfAnIndexFromYahoo(symbol):
url = 'http://finance.yahoo.com/q/cp?s=%s' % symbol
p = re.compile('<td class=\"yfnc_tabledata1\"><b><a
href=\"/q\?s=([A-Z0-9\.\-]*)\">')
components = []
pageIndex = 0
finished = False
while not finished:
if pageIndex == 0:
actualUrl = url
else:
actualUrl = url + "&c=" + str(pageIndex)
pageResults = p.findall(urllib2.urlopen(actualUrl).read())
if len(pageResults) == 0:
finished = True
else:
components.extend(pageResults)
pageIndex+=1
return components
# prices = data[:,6] or prices = data[:, title.index("Adj Close")],
pl.num2date(data[:,1]) back dates
# syntax
http://ichart.yahoo.com/table.csv?s={Yahoo.Symbol.[isin]}&a={Von.M-1}&b={Von.T}&c={Von.J}&d={Bis.M}&e={Bis.T}&f={Bis.
J}&g=d&y=0&z=jdsu&ignore=.csv
def getNumpyHistoricalTimeseries(symbol,fromDate, toDate):
f = urllib2.urlopen('http://ichart.yahoo.com/table.csv?a='+
str(fromDate.month -1) +'&c='+ str(fromDate.year) +'&b=' + str(fromDate.day) +
'&e='+ str(toDate.day) + '&d='+ str(toDate.month-1) +'&g=d&f=' +
str(toDate.year) + '&s=' + symbol + '&ignore=.csv')
header = f.readline().strip().split(",")
#return np.loadtxt(f, dtype=np.float, delimiter=",", converters={0:
pl.datestr2num})
I commented out the import pylab as pl because I couldn't get the
matplotlib.pylab import working. So, anyway, I hit F5, and it seems to run,
but it doesn't really do anything. Isn't this either supposed to be
downloading data from the web, or throwing an error so I can troubleshoot, and
try to figure out what's going on? It's hard to troubleshoot, when you don't
get any error. Does this work for others?
Thanks.
