I'm not sure if this is a Quandl problem, or a personal issue, but I can't access a Quandl database for VIX futures.
I'm running Q217, just installed the Quandl extension package. It works to call up a symbol if I use the default WIKI database (in the tester), but problems with other things like actually using it:
I can't seem to access CHRIS/CBOE_VX1 (or 2, 3, 4... any of the continuous VIX futures) as a data source. These report as NULL values in the tester, and if I configure a Quandl indicator to try and use one of them, it shows up as NaN with no graphed data shown.
I can't get the example in the extension docs to work either, the one with SF1 and @_EQUITY_MRQ. Also gives me NaN.
The Fear and Greed indicator works. So I am getting through to Quandl with my API, but unsure of the reason for these problems. Configuration? WIKI is set as my default.
