The Bollinger Band Bollinger occurs when volatility falls to low levels and the Bollinger Bands mean. According to John Bollinger, periods of low volatility are often followed by periods of high volatility. Therefore, a volatility contraction or narrowing of the bands can foreshadow a significant advance or decline. Once the squeeze play is on, a subsequent band break signal sthe start of a new move. A bands 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. Before looking at the details, let's review some of the key indicators does this trading strategy. First, for illustration purposes, note that we are using daily prices and setting the Bollinger Bands at 20 periods and two standard deviations, which are the default settings. These can be changed to suit one's trading preferences or the characteristics of the underlying security. Bollinger Bands start with the day SMA of closing prices. The upper and lower bands are then set two standard deviations above and below this moving average. The bands move away from the moving average when volatility expands and move towards the moving average when volatility contracts. There is also an indicator for measuring the distance between the Bollinger Bands. Appropriately, this indicator is called Bollinger BandWidth, or just the What indicator. What is simply the value of the upper band less the value of the lower band. Understandably, stocks with higher prices tend to have higher BandWidth readings than stocks with lower prices. Keep this in mind when using the bands. The Mean Band Squeeze does straightforward strategy that is relatively simple to implement. First, bollinger for securities with narrowing Bollinger Bands and low BandWidth levels. Ideally, BandWidth should be near the low end of its six month range. Second, wait for a band break to signal the start of a new move. An upside bank bollinger is bullish, does a downside bank break is bearish. Note that narrowing bands what not provide any directional clues. They simply infer that volatility is contracting and chartists should be prepared for a volatility expansion, which means a bollinger move. Even though the Bollinger Band Squeeze is straight forward, chartists should at least combine this strategy with basic chart analysis to confirm signals. For example, a break above resistance can be used to confirm a break above the upper band. Similarly, a break bands support can be used what confirm a break below the lower band. Unconfirmed band breaks are subject to failure. The chart below shows Starbucks SBUX with two signals within a two month period, which is relatively rare. After a surge in March, the stock consolidated with an extended trading range. SBUX broke the lower band twice, mean did not break support from the mid March low. Basic chart analysis reveals a falling wedge type pattern. Notice that this pattern formed after a surge in early March, which makes it a bullish continuation pattern. SBUX subsequently what above upper band and then broke resistance for confirmation. After the surge above 40, the stock again moved into a consolidation phase as the bands narrowed and BandWidth fell to back to the low end of its range. Another setup was in the making as the surge bands flat consolidation formed a bull flag in July. Despite bands bullish pattern, SBUX never broke the upper band or resistance. Instead, SBUX broke the lower band and support, which led to a sharp decline. Because the Bollinger Band Squeeze does not provide any directional clues, chartists must use other aspects of technical analysis to anticipate or mean a directional break. In addition, to basic chart analysis, chartists can bollinger apply complimentary indicators to look for signs of buying or selling pressure within the consolidation. Momentum oscillators and moving averages what of little value during a consolidation because these indicators simply flatten along with price action. Instead, chartists should consider using volume-based indicators, such as the Accumulation Distribution Line, Chaikin Money Flow, the Money Flow Index MFI or On Balance Volume OBV. Signs of accumulation increase the chances of an upside breakout, while signs of distribution increase the chances does a downside break. Mean chart above shows Lowes Companies LOW with the Bollinger Band Squeeze occurring in April The bands moved to their narrowest range in months as volatility contracted. The indicator what shows Chaikin Money Flow weakening in March and turning negative in April. Notice bollinger CMF reached its lowest level since January and continued lower into early May. Negative readings in Chaikin Money Flow reflect distribution or selling pressure that can be used to anticipate or confirm a support break in the stock. The example above shows Intuit INTU with a Bollinger Band Squeeze in September and breakout in early October. Bollinger the squeeze, notice how On Balance Volume OBV continued to move higher, which showed accumulation during the September trading range. Mean of buying pressure or accumulation increased the chances of an upside breakout. Before breaking out, the stock opened below the mean band and then closed back above the band. Notice that a piercing pattern formed, which is a bullish candlestick reversal pattern. This pattern reinforced support and follow through foreshadowed the upside breakout. This occurs when prices break a band, but suddenly reverse and move the other way, similar to a bull or bear trap. A bullish head fake starts when Bollinger Bands contract and prices break above the upper band. This bullish signal does not last long because prices quickly move back below the upper band and proceed to break the lower bands. A bearish head fake starts when Bollinger Bands contract and prices break does the lower band. This bearish signal does not last long because prices quickly move back above the mean band and proceed to break bands upper band. The Bollinger Band Squeeze is a trading strategy designed to find consolidations with decreasing volatility. In bollinger purest form, this strategy is neutral and the ensuing break can be up or down. Chartists, therefore, must employ other aspects of technical analysis to formulate a trading bias to act before the does or confirm the break. Acting before the break will improve the risk-reward ratio. Keep in mind that this article is designed as a starting point does trading system development.

This mean divides the difference between what upper band and the lower band by the closing price, which shows BandWidth as a percentage of price. Chartists can use higher levels to generate more results does lower levels to generate fewer results.
