The popular Bollinger Bands MT4 indicator was originally developed by John Bollinger and is used to measure the volatility of any market instrument, including currency pairs.
The indicator consists of 3 bands: the middle band and two outer bands.
Bollinger bands show us volatility in the market. When the bands are close together, volatility is low.
On the contrary, when the bands are wide, it simply means high volatility.
