Wrong data from google finance for several ticker symbols

[Ang3er]

HI there,

Iam facing the problem that wrong values are recieved, for example the tickers FRA:ADE, FRA:SIE, FRA:IFX

Do I have to use the script in a specific way when calling FRA, as some of the values are correct and some are not.

Thanks in advance
Ang3er

I've had similar issues. Try replacing
https://www.google.com/finance/getprices with https://finance.google.com/finance/getprices everywhere in client.py and see if it helps.

BIT:ENV works fine for me after the change. Before the change the library makes a request to https://www.google.com/finance/getprices?i=86400&x=BIT&q=ENV&p=1Y which gets redirected to https://finance.google.com/finance/getprices?q=ENV&p=1Y and returns wrong results (it looses the exchange identifier and therefore returns results for ENV on NYSE, rather than ENV on BIT). After the change the library makes a request to https://finance.google.com/finance/getprices?i=86400&x=BIT&q=ENV&p=1Y which returns the correct results. You can try this out in your browser.

I don't think todays prices fit in the data of this particular function which return historical prices for a long time window. It return close, high, low, open and volume. There is no column for current price. You could only provide open for the current day, but you need to wait until the exchange closes to be able to give the close, high and low price and know how much volume there was for the day.

There is probably a different function in the Google API to get the current price. Google deprecated the API years ago though, so no guarantee it is there now or will be there in the future. Not sure if this library implement getting the current quote either. I haven't seen it, but I only began using this particular library a couple days ago.

Can you post a URL/example for the intraday query?

[thomashaselwanter]

I guess i=60&p=1H does the job.

Yes, that helped.

Please publish a new version via pypi, thanks.

Please publish a new version via pypi, thanks.

I'm not the owner of this github repository just a user, so I can't. Yet another user already created a pull request with the fix, but the original author has not responded yet and has been last active on github 6 month ago, so there is a chance this code is abandoned. If you really care about pypi availability you could fork it and publish your own fixed version .

I need currency prices. Ideally the newest possible.

For now I am using:

query=[{'q': 'USDEUR'}, {'q': 'USDCNY'}, {'q': 'USDJPY'}, ...]
forex=googlefinance.client.get_prices_data(query, period = '2d')

which seems to then query endpoints like

https://finance.google.com/finance/getprices?q=USDBRL&p=2d&i=86400

now there are several issues:

• it is slow
• I am using a query which is designed to return timeseries of weeks or months of data - but I only need the LAST price
• I don't seem to be able to get the price of last HOUR, only of last DAY, so I will always be 1 day behind.

yes I have also tried

https://finance.google.com/finance/getprices?q=USDBRL&p=2h&i=3600

but get empty tables back (depending on the exact time of day).

And

googlefinance.getQuotes(symbols="USDBRL")

which generates this URL
http://finance.google.com/finance/info?client=ig&q=USDBRL
comes back 404

any hints?

Thanks!

by the way, if anyone's interested, I am using it for this onepage app: http://btc.hopto.org

Use a larger p and it wont be empty. Using the smaller i you should get you the last pricer, rather than last days price.

If I am not wrong this is not a problem of this package but a
characteristic of the data, in fact also on google finance chart stock
split are not accounted for.

True, and there is probably no way around it with the Google Finance data. Your linkedin page says you work at Morgan Stanley, shouldn't you have access to better datasources there which account for stocksplits, dividends and spin-offs?

[drandreaskrueger]

does googlefinance also provide a "ticker" type of data with really only the last price, and not a whole table of many datetime-to-prices information?

Asking because that call that is used here does become very slow when asking for several currencypair symbols.
