Using Bollinger Bands to Gauge Trends

In this trading method, the MACD is used as a momentum indicator, filtering false breakouts. Bollinger Bands are a technical indicatordeveloped by John Bollinger.

In fact, there are a number of uses for Bollinger Bands®, such as determining overbought and oversold levels, as a trend following tool, and for monitoring for breakouts. The 20-day simple moving average (X) that serves as the baseline for the Bollinger Bands® is in the centre of the zone. Developed bollinger bands tutorial by John Bollinger, Bollinger Bands® are volatility bands placed above and below a moving average. Volatility is based on the standard deviation, which changes as volatility increases and decreases. The bands automatically widen when volatility increases and contract when volatility decreases.

The bands move away from the moving average when volatility expands and move towards the moving average when volatility contracts. Bollinger Bands® are a type of chart indicator for technical analysis and have become widely used by traders in many markets, including stocks, futures, and currencies. Created by John Bollinger in the 1980s, the bands offer unique insights into price and volatility.

Some of his favored technical techniques are moving average divergence/convergence (MACD), on-balance volume and relative strength index (RSI). Before looking at the details, let’s review some of the key indicators for 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. The upper and lower bands are then set two standard deviations above and below this moving average.

The upper band is 2 standard deviations above the 20-period simple moving average. It takes a pretty strong price move to exceed this upper band. An upper band touch that occurs after a Bollinger Band bollinger bands tutorial confirmed W-Bottom would signal the start of an uptrend. Just as a strong uptrend produces numerous upper band tags, it is also common for prices to never reach the lower band during an uptrend.

They are simply one indicator designed to provide traders with information regarding price volatility. John Bollinger suggests using them with two or three meet the frugalwoods other non-correlated indicators that provide more direct market signals. He believes it is crucial to use indicators based on different types of data.

Their dynamic nature allows them to be used on different securities with the standard settings. For signals, Bollinger Bands can be used to identify M-Tops and W-Bottoms or to determine the strength of the trend.

Signals derived from narrowing BandWidth are discussed in the ChartSchool article on BandWidth. In the chart depicted below, Bollinger Bands® bracket the 20-day SMA of the stock with an upper and lower band along with the daily movements of the stock’s price.

Technically, prices are relatively high when above the upper band and relatively low when below the lower band. However, “relatively high” bollinger bands tutorial should not be regarded as bearish or as a sell signal. Likewise, “relatively low” should not be considered bullish or as a buy signal.

It takes strength to reach overbought levels and overbought conditions can extend in a strong bollinger bands uptrend. Similarly, prices can “walk the band” with numerous touches during a strong uptrend.

Because standard deviation is a measure of volatility, when the markets become more volatile the bands widen; during less volatile periods, the bands contract. Bollinger Bands® and Keltner Channels inform you when the market is transitioning from lowervolatility to higher volatility. Using these two indicators together is stronger than only using a single indicator, whereas both indicators should be used together.

During a strong trend, for example, the trader runs the risk of placing trades on the wrong side of the move because the indicator can flash overbought or oversold signals too soon. Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can be used to determine if prices are relatively high or low. According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant.

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. 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.

All of this can help you make better trading decisions if you follow a few simple guidelines. In range-bound markets, mean reversion strategies can work well, as prices travel between the two bands like a bouncing ball. However, Bollinger Bands® don’t always give accurate buy and sell signals.

The indicator forms a channel around the price movements of an asset. The channels are based on standard deviations and a moving bollinger bands average. Bollinger bands can help you establish a trend’s direction, spot potential reversals and monitor volatility.
