Futures, futures options, and forex trading services provided by Charles Schwab Futures & Forex LLC. They can be used to identify M-Tops and W-Bottoms or to determine the trend’s strength. Signals based on the distance between the upper and lower band, including the popular Bollinger Band Squeeze, are identified using the related Bollinger BandWidth indicator. If you are unfamiliar, Bollinger Bands Width is a measure of the distance between the top and bottom bands of Bollinger Bands.

So, you have multiple signals confirming the index is oversold. While we only cover double bottoms, you can apply the Bollinger bandwidth indicator to validate other chart patterns. BBW indicator works as an oscillator and depends on the volatility. High market volatility increases the BBW while the flat market decreases the BBW.

What is the significance of the “Squeeze” in the Bollinger BandWidth context?

There are four steps to confirm a W-Bottom with Bollinger Bands. The ability to hold above the lower band on the test shows less weakness on the last decline. Fourth, the pattern is confirmed with a strong move off the second low and a resistance break. Supporting documentation for any claims, comparison, statistics, or other technical data will be supplied upon request.

Also, the use of 20-day SMA and 2 standard deviations is a bit arbitrary and may not work for everyone in every situation. Traders should adjust their SMA and standard deviation assumptions accordingly and monitor them. Sometimes, after a Squeeze, the initial band break might not hold, causing prices to reverse in the opposite direction.

• When two different time frame Bollinger Bands are travelling together then its a strong Support or Resistance Levels.
• Technical analysts can easily employ the Bollinger Band Width indicator to visualize consolidation before price fluctuations or high volatility periods.
• As with other indicators, Bollinger Bands are not meant to be used as a stand-alone tool.
• As you can see, the low points do not predict which way the market is going to break.

As Bollinger puts it, moves that touch or exceed the bands are not signals, but rather “tags”. On the face of it, a move to the upper band shows strength, while a sharp move to the lower band shows weakness. It takes strength to reach overbought levels and overbought conditions can extend in a strong uptrend. Similarly, prices can “walk the band” with numerous touches during a strong uptrend.

Yes, but it’s crucial to note that securities with lower volatility will naturally have lower BandWidth values than those with higher volatility. For instance, utility stocks generally have lower BandWidth values than technology stocks. An increasing BandWidth reflects increasing volatility in the price, while a decreasing BandWidth reflects decreasing volatility. The goal of the BBW indicator is to determine the nature of Bollinger Bands that can expand or contract based on volatility. BBW is obtained by dividing the difference between the upper and lower bands by the middle band.

In the meantime, we’d like to gift you our trading roadmap and its best 55 resources.

The indicator window shows the 10-period Commodity Channel Index (CCI). Dips below -100 are deemed oversold and moves back above -100 signal the start of an oversold bounce (green dotted line). CCI then identified tradable pullbacks with dips below -100. This is an example of combining Bollinger Bands with a momentum oscillator for trading signals.

Bollinger Bandwidth Indicator – 3 Trading Strategies

I have added 5 Min, 15 Min, 30 Min, 1 Hr and 1 Day time frame Bollinger Bands in one Chart. The BBWP is calculated for a short, medium and long timeframe,… Bollinger Band is simply a representation of the rolling average of price and its standard deviation around the average (called the “basis”). For a given data set, the standard deviation measures how far numbers are from an average value.

A new advance starts with a Squeeze and subsequent break above the upper band. A new decline starts with a Squeeze and subsequent break below the lower band. Bollinger Bands can be found in SharpCharts as a price overlay. As with a simple moving average, Bollinger Bands should be shown on top of a price plot. Upon selecting Bollinger Bands, the default setting will appear in the parameters window (20,2). The first number (20) sets the periods for the simple moving average and the standard deviation.

Bollinger Bands Width Explained!

The 200-day moving average of XLU BandWidth is below 5, while the 200-day moving average of XLK BandWidth is above 7. BandWidth values should be gauged relative to prior BandWidth values over a period of time. It is important to get a good look-back period to define BandWidth range for a particular ETF, index or stock. For example, an eight- to twelve-month chart will show BandWidth highs and lows over a significant timeframe. BandWidth is considered narrow as it approaches the lows of this range and wide as it approaches the high end. The upper and lower bands are typically two standard deviations from the SMA.

According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant. Technically, prices are relatively high when they’re above the upper band and relatively low when below the lower band. However, “relatively high” should not be regarded as bearish or a sell signal.

Bollinger Bandwidth – Bulge and squeeze

With the subsequent surge above the upper band, the stock broke out to trigger an extended advance. The Bollinger Bands Width is an extension of the Bollinger Bands Indicator, both of which are useful technical indicators to identify The Squeeze and bollinger bands bandwidth its resultant volatility. This indicator created to identify the strong Support and Resistance levels based on the Bollinger Bands. When two different time frame Bollinger Bands are travelling together then its a strong Support or Resistance Levels.

The difference is then divided by the value of the middle band which is the 20-period SMA. There are three main factors in the Bollinger Bands %B, price, upper band, and lower band. %B indicator and its calculations are all about the six basic relationships between those three factors. This scan reveals stocks whose Bollinger Bands just expanded rapidly after being contracted for 5 or more days. The opposite of The Squeeze happens when Bollinger Bands Width expands.

Likewise, “relatively low” should not be considered bullish or a buy signal. As with other indicators, Bollinger Bands are not meant to be used as a stand-alone tool. Chartists should combine Bollinger Bands with basic trend analysis and other indicators for confirmation. Bollinger Bands® are highly technical tools that give traders an idea of where the market is moving based on prices.
