When it happens, it means that there is a likelihood that a bullish or bearish breakout will happen. On the other hand, the Bollinger Bandwidth is used as a measure of volatility. For example as look at the chart below shows that the bandwidth moved in a horizontal way for a long time. For example, there are those who use Bollinger Bands in trend-following and those who use it to find reversals. This happens by looking at where the price is in relation to the Bollinger Bands indicator. Here, the Middle Band represents the simple moving average, which allows you to calculate the BBW relative to the average price.
Short selling is an advanced trading strategy involving potentially unlimited risks and must be done in a margin account. For more information, please refer to your account agreement and the Margin Risk Disclosure Statement. Narrow bands indicate a squeeze, which means that volatility is low. But remember, since volatility is mean-reverting, the bands will probably expand, signaling a potential for an explosive move. A simple way to spot a squeeze is to identify when the bands are the narrowest they have been for the last six months. If memory serves me correctly, Bollinger Bands, moving averages, and volume were my first indicators as a beginner trader.
Are There Any Limitations to Bollinger Bands®?
Looking at the increase in volatility or higher Bollinger Bandwidth value on the USD/JPY daily chart, it shows USD/JPY reaching new lows outlined by the square boxes. This parabolic movement in price and rising volatility does hint at a potential trend reversal (to the upside in this case). When the bandwidth is narrow, it means that there is no volatility in the market.

BandWidth dipped below 10 to put the Squeeze play on in mid-June. In other words, the width of the bands is equal to 10% of the middle band. Even though this level seems high, it is actually quite low for ALK. With the stock around 15-16, BandWidth was less than 10% and at its lowest level in over a year. With the subsequent surge above the upper band, the stock broke out to trigger an extended advance. BandWidth values should be gauged relative to prior BandWidth values over a period of time.
How does the Bollinger Band Width indicator work?
Bollinger Bands® was developed by technical trader John Bollinger and designed to give investors a higher probability of identifying when an asset is oversold or overbought. Bollinger Bands generate different values that change with movements in the underlying market value of the asset. In other words, when the market activity becomes more volatile, the bands will spread farther apart. The single biggest mistake that many Bollinger Band novices make is selling the stock when the price touches the upper band or buy when it reaches the lower band. Bollinger himself stated a touch of the upper band or lower band does not constitute a buy or sell signal. It is also preferable to see the upper and lower band starting to widen in a breakout scenario.
Can BandWidth values be compared across different securities?
Over the years there have been many variations on bands and envelopes, some of which are still in use. In the 1980s, John Bollinger, a long-time technician of the markets, developed the technique of using a moving average with two trading bands above and below it. Unlike a percentage calculation from a normal moving average, Bollinger Bands® simply add and subtract a standard deviation calculation. The fact that the second high is within the upper band suggests that it is a lower high on a relative basis. Flexible and visually intuitive to many traders, Bollinger Bands® can be a helpful technical analysis tool.
On the secondary test, TRCH tested a new low with a 40% drop in traffic from the last swing low. Many Bollinger Band technicians look for this retest bar to print inside the lower band. This indicates that the downward pressure in the stock has subsided and there is a shift from sellers to buyers. Also, pay close attention to the volume; you need to see it drop off dramatically. It’s better to stick with 20, as this is the value most traders are using to make their decisions, versus trying to look for a secret setting. In essence, the Bollinger Band indicator was created to contain price the vast majority of the time.

Notice how the price and volume broke when approaching the head fake highs (red line). If you are new to trading, you are going to lose money at some point.

By default, the upper and lower bands are set two standard deviations above and below the moving average. However, traders can customize the number of periods in the moving average as well as the number of deviations. The Bollinger Band Width (BBW) indicator is a technical analysis tool derived from the Bollinger band. BBW is actually the width between the upper and lower Bollinger bands divided by the middle band.
In every scenario, the break of the lower band was in oversold territory. Stocks that break the lower Bollinger Band® and enter oversold territory face heavy selling pressure. When this pressure is not corrected, the stocks continued to make new lows and continue into oversold territory. To effectively use this strategy, a good exit strategy is in order. Stop-loss orders are the best way to protect you from a stock that will continue to ride the lower band down and make new lows.
