What Is India VIX?

The India VIX (Volatility Index) is a real-time index computed by the National Stock Exchange (NSE) that measures market expectations of near-term volatility over the next 30 calendar days.

Often referred to as the "Fear Gauge" or "Investor Sentiment Meter", India VIX is calculated using the order book of near and mid-month NIFTY index options contracts according to the Black-Scholes volatility computation framework.
