In the previous post, we discussed what volatility is and the differences between Historical Volatility (HV) and Implied Volatility (IV). Now, we�ll carry on with some websites for obtaining volatility information.
How To Get HV and IV Info
The following are the sources from which I usually find HV and IV info for FREE:
1) ivolatility.com.
This site provides some tools & data such as:
- Stock�s Historical Volatility (HV) and Implied Volatility (IV) figures (1 day lag).
- IV and Delta figures for near ATM options (No other Options Greeks info).
- Options Calculator.
It can be found under �Analysis Service� >> �Basic Calculator� at the left bar. - Volatility Charts.
This chart shows Historical Volatility (HV) and Implied Volatility (IV) for 3 months, 6 months, and 1 year window (The charts are located at the right side). Advantage: What I like from the Volatility Chart in this site is that the time-scale (in terms of months) in the horizontal axis is very clear. Hence, it�s easier to make quick comparison between months.
Disadvantage: The stock price is plotted separately from HV vs. IV. Not too straightforward for analysis & comparison.

2) My options broker: OptionsXpress.
Here are volatility related tools / info I use from this site:
- Real-time IV figures for various strike prices and expiration months (not only near ATM options).
- Options Pricer.
This tool can be used to calculate theoretical option�s price (options calculator), as well as to show the real-time Options Greeks data (Delta, Gamma, Rho, Theta, and Vega). - Volatility Chart.
This chart shows Historical Volatility (HV) and Implied Volatility (IV) vs. Stock Price for 3 months, 6 months, and 1 year window.
Advantage: HV vs. IV vs. stock price, all plotted in one chart. It�s easier for analysis & comparison (e.g. The reason why there is a drastic surge in HV is because of the price gap up / down due to earnings announcement).
Disadvantage: The time-scale (in terms of months) in the horizontal axis is not very straightforward. Hence, it�s more difficult to make quick comparison between months.
