  1. does anyone know if IB's Show Volatility button under OptionTrader that converts all option bid/ask to % volatility is the historical or implied volatility, or something else? It has a different percent value than the Imp. Vol column that's right next to it. thanks

  2. Implied on bid and ask separately. The Imp. Vol column is based on bid/ask *average*. All are derived from Option Model settings.
  3. thank you sir
