Alternatywa dla google finance api [zamknięta]

Jestem spóźniony, ale zobacz Quandl . Mają API dla cen akcji i fundamentals .

Oto przykładowe wywołanie używając quandl-api download w csv

Przykład:

https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31

Wspierają te języki . Ich dane źródłowe pochodzą z Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE i innych (zobacz tutaj ).

Sugerowałbym użycie TradeKing ' s developer API. Jest bardzo dobry i darmowy w użyciu. Wszystko, co jest wymagane, to to, że masz u nich Konto i według mojej wiedzy nie musisz nosić salda ... tylko do rejestracji.

Jeśli nadal chcesz korzystać z Google Finance dla swoich danych, możesz Sprawdzić to.

Ostatnio musiałem sprawdzić, czy dane SGX są rzeczywiście odzyskiwalne przez Google finance (i oczywiście spotkałem się z tym samym problemem co ty)

Podążałem za najlepszą odpowiedzią i zacząłem szukać yahoo finance. Ich API można uzyskać na wiele różnych sposobów, ale znalazłem dobre odniesienie do uzyskiwania informacji o zapasach jako plik CSV tutaj: http://www.jarloo.com/

Używając tego napisałem ten skrypt. Nie jestem facetem od ruby, ale to może pomóc ci coś zhakować. Nie wymyśliłem jeszcze nazw zmiennych dla wszystkich pól, które yahoo oferuje, więc możesz je wypełnić, jeśli ich potrzebujesz.

Oto użycie

AllData = loadStockInfo(TICKERS_SP500, allParameters())

SpecificData = loadStockInfo("GOOG,CIK", "ask,dps")

LoadStockInfo zwraca hash, taki, że SpecificData ["GOOG"] ["nazwa"] to " Google Inc."
