Probably not the right site to ask this, but how can I find out the Quandl codes for different commodities? For example, gold against USD? Tried "CURRFX/XAUUSD", but no joy. Here is the code for plotting GBP against USD:

  Rest @ 
      startDate -> "2016-6-1", endDate -> "2016-6-23", column -> 2], 
  ImageSize -> 400]

    $\begingroup$ Would something like this free Quandl database link to the World Gold Council (quandl.com/data/WGC) work for you? The code seems to be "WGC/GOLD_DAILY_USD". I found that through their database browser. $\endgroup$ – MarcoB Jun 24 '16 at 14:08
  • $\begingroup$ @MarcoB It works - thanks :) $\endgroup$ – martin Jun 24 '16 at 14:16
  • $\begingroup$ You're welcome! Would you mind putting together a quick self-answer, pointing to the QuandlLink` package, and to the database browser as well, for future reference? This could be very useful for future searchers! $\endgroup$ – MarcoB Jun 24 '16 at 14:21
  • $\begingroup$ @MarcoB will do $\endgroup$ – martin Jun 24 '16 at 14:23

Answer posted for the benefit of future users of the Quandl package for MMA by Anmol Bajracharya, also described in this Wolfram Community post.

Thanks to @MarcoB's search through Quandl's database browser, he found a link to the World Gold Council. Using the code "WGC/GOLD_DAILY_USD" works in this case:

<< QuandlLink`

      startDate -> "2016-6-1", endDate -> "2016-6-23", 
      column -> 2
   ImageSize -> 400

    $\begingroup$ Martin Thanks for drafting this. $\endgroup$ – MarcoB Jun 24 '16 at 18:14

Slight modification to martin's answer to address recent changes in Ma.

QuandlOneSeries[symbol_, stDate_, endDate_] := Module[{data, dates, datav, datats},
  data = Import[StringJoin["https://www.quandl.com/api/v3/datasets/", symbol, 
     "/data.csv?start_date=", stDate, "&end_date=", endDate, 
  dates = ToExpression[StringSplit[data[[2 ;;, 1]], "-"]];
  datav = data[[2 ;;, 2]];
  datats = TimeSeries[datav, {dates}];

Using above function, data can be downloaded and DateListPlot can be used to plot it as follows:

DateListPlot[QuandlOneSeries["WGC/GOLD_DAILY_USD", "1975-03-31", "2019-05-31"],
GridLines -> Automatic]

enter image description here


Alternatively, get an API key from here (free), and use something like the following:

quandl[dataset_, startdate_, enddate_, apikey_] := 
dataset, ".json?api_key=", apikey, "&start_date=", startdate, 
"&end_date=", enddate]][[1, 2, 6, 2]];

which gives

DateListPlot[quandl["WGC/GOLD_DAILY_USD", "1980-01-01", "2016-06-24", 
(*your API key*)]]
