Bollinger Bands® Understanding How Bollinger Bands Work

bollinger bands

It’s most helpful paired with other technical analysis indicators, as well as fundamental analysis conclusions about the stock in question. A squeeze, in the context of Bollinger Bands, refers to a period of low volatility during which the upper and lower bands converge upon the simple moving average. Periods of lower volatility, by definition, are periods of low dispersion. In other words, the price tends to fluctuate closely to the simple moving average.

Are Bollinger Bands helpful?

Bollinger Bands can be a useful tool for traders in assessing the volatility of their position, providing them with insight on when to enter and exit a position. For forex traders, certain aspects of Bollinger Bands, such as the Squeeze, work well for currency trading, as does adding a second set of Bollinger Bands.

Another drawback is that they are calculated using a simple moving average. That’s because older price data is weighted in the same way as recent data. Because Bollinger Bands® are computed from a simple moving average, they weigh older price data the same as the most recent, meaning that new information may be diluted by outdated data. 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. Technical analysis focuses on market action — specifically, volume and price.

Using Bollinger Bands for Breakout Trades

Because they are tools, not a system, and because Bollinger Bands applications are so diverse, they continue to work year after year as they are adapted and applied in new ways. To fully grasp the potential of Bollinger Bands, traders can study real-life examples and case studies of successful Bollinger Bands applications. These examples can provide insights into how Bollinger Bands work in various market conditions and how traders have used them to generate profitable trading signals. Traders can apply Bollinger Bands to various timeframes, such as daily, hourly, or minute charts.

Remember to adjust your stop orders as needed, or consider using a trailing stop designated in either a fixed dollar amount or a fixed percentage. Another method would be to use the parabolic SAR indicator to trail your stop. Finally, to capture longer moves, you could consider exiting when the stock tags the opposite band (i.e., the lower band if you’re long, or the upper band if you’re short). To identify a double bottom, look for bollinger bands a price that has touched the lower band and wait to see where the next low occurs. A price that reacts and rises close to the middle band, followed by a second low inside the lower band, suggests that the price is positioned for an upward move—a good time for traders to buy. If the upper and lower bands are 1 standard deviation, this means that about 68% of price moves that have occurred recently are CONTAINED within these bands.

How Do Traders Use Bollinger Bands?

Bollinger bands are a momentum indicator that can be used to determine whether a price is moving higher or lower. It helps traders visualise volatility and determine when a trend is likely to continue or reverse. When price movements closely follow the middle band, traders consider the instrument to be trading within its average range. Chart 5 shows Pulte Homes (PHM) within an uptrend in July-August 2008. Price exceeded the upper band in early September to affirm the uptrend.

What is the best Bollinger Band strategy?

The Bollinger band moving average strategy is simple to implement. If the price crosses above the middle line (moving average) it gives the buy signal, because it depicts the uptrend. It's wise to exit the market if the price crosses below the moving average.

Anchored Volatility Stop

When a security’s price approaches the upper band, it may be considered overbought, while a price approaching the lower band may be considered oversold. Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can 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. Technically, prices are relatively high when they’re above the upper band and relatively low when below the lower band.
