So what wud be the best way to first know this & second utilize this?

Can I use INDIAVIX as Volatility for Nifty Options in Options Calc?

OR

Should I use the Applicable Annualised Volatility data from Daily Volatility files from Nseindia?

Pls let me know.

Thanks

Not to get too technical, when the VIX is at 30, it means that the S&P-500 might move as much as 2.5% (30% divided by 12 months). When the market is trending steadily upwards, there is generally a low level of volatility in the market as complacency sets in and more call options are bought than put options. Conversely, when a market is falling, there is generally widespread panic in the market causing a high level of volatility as more put options are bought than call options. This correlation is also why the Put Call Ratio is read in conjunction with the VIX to provide more insight into the state of volatility in the market. Together, the Put Call Ratio and the VIX have been known as "investor fear gauges". The correlation between the VIX and the state of the market is uncanny. This is why the VIX is useful not only for options traders as stock traders and investors also use the VIX as a market timing devise or a contrarian indicator. As a contrarian indicator, the higher the VIX, the more bearish the market is and conversely, the lower the VIX, the more bullish the market is. VIX is also a direct indication of the level of implied volatility in the options market. The higher the VIX, the more profitable credit spreads and naked writes become due to the fact that all options contains relative higher extrinsic value than when the VIX is low. Options traders could therefore change options strategies as the market conditions change, favoring debit spreads when the VIX is low and credit spreads when the VIX is high. The real question now is, when is the VIX high or low? There really isn't a standard to what constitutes a high or low VIX reading. Apart from using your experience and gut feel, there are 2 main ways to read the VIX. 1, Multi-years high or low. 2, VIX trend. Multi-year highs or lows typically warns investors that turning points may be near. The above examples marked two market reversals when the VIX was in multi-year high and low. Investors and traders may consider covering or closing profitable positions when these points are reached. The trend of the VIX also provides an indication to the trend of the stock market. In a bull market, the VIX is typically trending downwards and in a bear market, the VIX is typically trending upwards. -- Excerpted from OptionTradingPedia.com with editing for brevity.

Thanks very very much Xyte for such a nice & detailed explanation on VIX. I m so glad to be a part of such a lovely forum wherein seniors dont hesitate to help newbie's like me on any topic. This is really a great heads up & certainly very useful...

Also, I am sure that you are aware of the difference between implied volatility and historical volatility. Both are totally different ( search investopedia.com ) As Xyte sir mentioned VIX data from nse site would be sufficient to understand price behavior along with VIX, however Indian vix started after sub prime crisis, after market meltdown during sub-prime crisis there was very interesting study on VIX, you can get the chart of CBOE VIX compare to s&p for study during that phase. Most of the time VIX is useful to predict major top and major bottom that is extremes of market.

Thanks much Alex. Looks like I need to dive more deeper on this topic...looks pretty interesting..The more Im learning the more curious I become whats next?

Thx for sharing ur inputs today..much appreciated..

Cheers

For Nifty options calc INDIAVIX is best For stock options we don't have the implied vols in any case.

Annualised vol can be used to see how much the implied vol (which can be viewed as vol futures ) is deviating from it, but not generally used.
