The exchange rate of currency pair denotes the level of volatility in the market. By observing the past records of level of volatility and by plotting the exchange rate using Bollinger Bands you can also determine the past data. By looking the level of the volatility of the currency pair used to option the price the traders can estimate the level of volatility of future.
Future Risk and Implied Volatility
By determining the fair price value of the forex currency option forex traders can routinely assess the level of volatility in the future is an example.
Implied volatility as you know is the option price which are commonly expire on a particular time period in future with the determination in volatility level driven by the market. Annualized percentage is usually used to express the level of volatility.

The price movement can be observed with the help of the standard deviation that are annualized for some particular periods and this can be indicated by using an indicator known as historical volatility.
Market Volatility and Bollinger Bands
Another type of indicator use to measure the past volatility is the Bollinger Bands. In this type of measurement certain numbers are plotted using standard deviations which are superimposed with the currency pair and its price action for a moving average.
