How to know if the share is high or low volatile?

I was going through subject of volatility but not clear about it. So, how to know that whether the script is High or low volatile.

One thing i read is that we can check the script chart. if it has high fluctuations than it is high in volatility and vice-versa.

What are some examples of Low volatile shares in Nifty? Is hindalco a High/low volatile share?

hie as of my knowledge . volatility is nothing but (high-low) . if you plot that on any specific instrument you can get the spread it had from high of specific time to its low . but for generally we see volatility of index in vix its computed based on options .

you can Bollinger band indicator to identify weather particular stock is high in volatile or not. 

Bollinger band is an indicator used to measure the volatility. Bollinger band Contracts when particular stock is less volatile and expands on high volatility. Bollinger band can be plotted on the chart even on kite and zerodha pi.
