I need to get the current spot/price on VIX. I use this to Initialize(self):

 

#VIX
vix = 'CBOE/VIX'
self.AddData(QuandlVix, vix, Resolution.Daily)
self.vix_sma = self.SMA(vix, 10, Resolution.Daily, Field.Close)

How do I get self.vix to use in other methods? I would settle for the current day open or previous day close as well if we can't get current spot
