Introduction:

Volatility: When the prices involved in trade activity are observed, we find that there is a change in the price from time to time-based on the market scenario. This is quite obvious. The degree of range of the changing prices can be measured with the help of a standard deviation of logarithmic returns. The value obtained can be defined as ‘volatility’.
