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 BBW 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.

Indicator Formula

The computation of the bandwidth indicator is as follow:

Band Width = [ (Upper Bollinger Band – Lower Bollinger Band) / Middle Bollinger Band ]

How to trade with this indicator?

Bollinger band width indicator is an oscillator that depends on the volatility. However, the volatility doesn’t give any trading signals because it is not a trend.

So, CFD traders in Tradingview notice the change in volatility once they use the Bollinger bandwidth indicator. This volatility can tell you the level of your reward according to the risk taken. High volatility means that you took a high risk so you have a high reward. And vice versa.

Bollinger band Vs Bollinger bandwidth

The Bollinger band refers to bands placed on a chart to present the volatility in the stock market and it consists of three lines drawn in relation to price. But Bollinger bandwidth consists in fact of a single line drawn below the chart price of the bollinger bands in simple words, it calculates the difference between the upper and lower bollinger bands and divides them by the middle band.

Therefore BBW calculates the volatility in the stock market as we said earlier, according to the Bollinger bands.

Moreover, when you have a high BBW indicator, it will be presented in the price chart by an increase in the distance of the outer bands. But if you have a low BBW indicator it marks by a decrease in the distance between the upper and lower bollinger bands.
