Market Synopsis
Using the Black Scholes option pricing model calculation, plots the implied volatility of an option based on the current option price and the underlying symbol price. If the study is applied to a symbol other than a stock option, index option, or futures option, a runtime error is thrown.
This study calculates the real-time implied volatility based on quote fields and does not calculate historical bar values. Since the study calculates the values based on quote fields, the values may not match those seen in Charting with the "Impl Volty- 1 Option" indicator, which is bar-based and uses close prices.
For the option price, the "mid" price ((InsideBid + InsideAsk) * 0.5) is used. For the underlying price, the "Last" price is used. If there is missing data (option Bid, option Ask, or Underlying Last), an exception is thrown.
This study can update outside of regular session hours if the Underlying or option price changes (for example, in pre-market or post-market session).
A grid-based (RadarScreen) indicator.
