Interaction with Alpha Vantage?

(Please include r-sig-finance in your replies so that others may benefit from this exchange.)
Good question, but, no, I haven't. I don't depend upon AlphaVantage for FX rates; hence, I've never tried downloading FX data.?Paul Teetor, Elgin, IL USAhttp://quantdevel.com/public

Paul have you tried FX download in Alphavantage? I tried all the lines below in R and all work apart from the last one for FX. Marco

data = av_get(symbol = "INGA.AS", av_fun = "TIME_SERIES_DAILY", datatype="csv", outputsize = "full")?????? #-- holland, amsterdam
data = av_get(symbol = "ABB.ST", av_fun = "TIME_SERIES_DAILY", datatype="csv", outputsize = "full")??????? #-- sweden, stockholm
data = av_get(symbol = "RELIANCE.NS", av_fun = "TIME_SERIES_DAILY", datatype="csv", outputsize = "full")?? #-- india nifty constituent
data = av_get(symbol = "DJI", av_fun = "TIME_SERIES_DAILY_ADJUSTED", datatype="csv", outputsize = "full")
data = av_get(symbol = "GS", av_fun = "TIME_SERIES_DAILY_ADJUSTED", datatype="csv", outputsize = "full")

data = av_get(from_currency = "USD", to_currency = "EUR", av_fun = "CURRENCY_EXCHANGE_RATE")

Early in the development of the AlphaVantage code for quantmod, I contacted support at alphavantage.co with a bug report. They replied quickly and fixed the problem.

Later, I found another problem, which I reported, too. On one hand, they never replied to that e-mail. On the other hand, the problem disappeared. It left me with the impression that someone was monitoring that address but without time to spare.

I do occasionally get HTTP 503 errors (Service Unavailable) when I run my downloader late at night. Have not noticed problems beyond that since they fixed the first two.

To be fair, as long as we're not being spammed and the data works, (and
it's free), ... and relatively accurate, I think we're okay.? (May or may
not be speaking from experience).

I can visualize a scenario where a few busy people are putting this
together.

I'm not so sure.? I haven't noticed any problems in their data (though

I haven't done extensive testing), but in my opinion it is a bad sign if
there's no way to contact them.

e.g. 2004-11-01

GS['2004-10-28/2004-11-03',' Low']

? ? ? ? ? ? ? ?Low
2004-10-28 95.80
2004-10-29 97.43
2004-11-01? 9.12
2004-11-02 98.50
2004-11-03 98.68

Did you try reporting that to Alpha Vantage?? That's the kind of thing
they did respond to on Aug 17 (see
https://github.com/ joshuaulrich/quantmod/issues/ 176).

Now that I read those messages more closely, it does appear they were in
touch with anozari sometime in July.? So perhaps it's just me they don't
respond to.? I was asking how to do things (and suggesting documentation
and metadata additions), I wasn't reporting on data errors.
