Technical analysis
Also called: Bollinger band
Bollinger Bands are three lines around price: a 20-period moving average in the middle and bands two standard deviations above and below it. The bands widen when prices swing more and narrow when they go quiet.
Middle = SMA(20); Upper = SMA(20) + 2 × σ(20); Lower = SMA(20) − 2 × σ(20)
With a 20-day average of ₹500 and a 20-day standard deviation of ₹10, the upper band is ₹520 and the lower band ₹480.
