Hello

I'm using the following to initialize the VIX data:

        # add underlying for option data
        self.opt_equity = self.AddData( CBOE, "VIX" )
        self.opt_equity.SetDataNormalizationMode(DataNormalizationMode.Raw) 

Than I'm using the following to get the Option Chain for the VIX options

self.OptionChainProvider.GetOptionContractList(self.opt_equity.Symbol, data.Time)

It looks like it does not like VIX.CBOE as an index, how to get the Options on the VIX?

Thankx for help

This is the code:
