Bollinger Band Width Indicator FAQ
What is Bollinger Band Width indicator ?
Bollinger band width Indicator shows the evolution of price volatility. Therefore it works as follows: when the volatility increases, the distance between the upper band and lower band will expand and the band width value rises. Conversely, when the volatility decreases, the distance between these two bands will contract then the band width.
In addition, when the two bands (the upper and the lower) are far apart, this is an indication that the current direction is nearing an end, but when the distance between them is narrow that is an indication that there is an initiation of a movement in either direction.
The Bollinger band width indicator contains a middle band with two outer bands. However, these bands in mt5 use the same parameters as the Bollinger band which are:
- Simple moving-average period: for the middle band, usually set at 20 periods.
- Standard deviation: for the outer bands, usually set 2 standard deviations above or below the SMA.
