Answer 1

You can find the formula here:

Most trading sofware includes the Bollinger Bands, which are simply two standard deviations on each side of a moving average.

The Beta Coefficient measures the systematic risk, or relative volatility, or financial elasticity of a stock, and will be much lower than the stock's standard deviation.

The standard deviation is defined as the square root of the variance. This means it is the root mean square (RMS) deviation from the arithmetic mean. The standard deviation is always a positive number (or zero).

You can look thru the bloomberg if you have one. ut since u asked such question i presume you may not have it. You can calculate it using the beta which is available mostly thru the newspaper or the stock exchange website.
