Implied Volatility on Options returns zero

Thanks @Venugopal! Options is in beta - please join the slack conversation here to hear about the updates: http://qnt.co/slack

Thank you Jared.

In case anyone else is having this issue, you need to set a pricing model as in this algo:

Hi, I'm also getting 0 for implied volatility.  I started w/ the basic algo from github 

for future options and added a pricing model.  I'd attach a backtest, but it's not showing in the list.

The following never triggers - 

            if contract.ImpliedVolatility > 0:
                self.Log(f"{contract} {contract.ImpliedVolatility}")
