Who knows offhand which of the charting packages offers historical volatility (HV) and implied volatility (IV) as technical studies to plot on their charts? I know eSignal and Qcharts don't. I think Ensign and Investor RT might. what about others, Metastock, Omnitrader, Tradestation? Of course I can always go to ivolatility.com, but it's not the same. Any option guys here with a tip? Thanks.
