Higher volatility increases standard deviation, widening the bands; lower volatility decreases it, contracting the bands—creating a dynamic, self-adjusting indicator. Bollinger Bandwidth is an indicator that measures the percentage difference between the upper and lower bands. The width normally wides when Bollinger Bands widens and then increases when the Bollinger Bands rises. Therefore, it is an important indicator used to measure volatility in the financial market. Bollinger Bands is a popular technical indicator that was developed by John Bollinger. It is a useful indicator that brings a new twist to the role of moving averages.
For example, in this chart, you can see the Bollinger band squeeze in the middle, from 21 November to 12 December before breaking out. We now move on to the main event, trying to figure out how to use Bollinger Bands to create a trading strategy. In addition to the Bollinger Bands, John Bollinger has said that we should look at the bandwidth of the band too, to help us in our analysis. Like Bollinger Bands, donchian channels is a technical indicator consisting of three lines.
Signaling the Start or the End of Trends
Never trade the squeeze in isolation—always use multiple confirming factors. During a squeeze breakout, measuring the previous width of the bands before contraction can give a rough estimate of the potential movement. For more precise targets, combine Bollinger Bands with other technical tools like Fibonacci extensions, pivot points, or measured moves from chart patterns.
Asset classes
A Bollinger Band squeeze can lead to a breakout, but it doesn’t specify the direction of the breakout. Some traders assume that a squeeze will result in an upward or downward movement, leading to premature entries. It’s crucial to wait for confirmation of the breakout direction before taking a position. This basic example outlines how to create a Bollinger Bands-based trading strategy in Python.
What Timeframes Works Best with the Bollinger bands?
A move outside of the outer Bollinger Bands ® shows a significant price move and is a 5% outlier. When you hear someone say “95% confidence interval,” it means they’re pretty certain (95% sure, to be exact) that the average price candle will fall within the range of the Bollinger Bands ®. If you’re 95% sure the price will stay within the Bollinger Bands ®, you can be confident about the price prediction. Again, I do not want to get too technical, but a small excursion is important to understand the approach of the Bollinger Bands® indicator and why it is so powerful. We do not want to get too technical in this article, but understanding the basic premise of the indicator will help us use the indicator more effectively.
The impact of market sentiment on Bollinger Bands Width can be huge because market sentiment can influence price volatility, which, in turn, influences Bollinger Bands Width. When market sentiment is high, the Bollinger Bands Width indicator is likely to rise, and when sentiment is low, the width decreases. In bollinger bands bandwidth the chart below, you can see a tight price consolidation (grey rectangle). Eventually, the price broke out of the rectangle (white arrow) and trended upward.
In addition, volume indicators can tell you about the strength behind a move, as significant price changes with a high volume could confirm signals from the Bollinger Bands. You can also adjust the settings of the Bollinger Bands by increasing the period of the moving average or the number of standard deviations, which might filter out less significant price moves. Bollinger Bands are a technical indicator created by John Bollinger, which appear as a pair of lines on a price chart. The line in the middle is typically a 20-day simple moving average (SMA), while the upper and lower bands are usually set 2 standard deviations above and below the middle line. Bollinger Bands can be used to measure market volatility, identify potential trend reversals and set entry and exit points.
Relation with the Bollinger Bands
As mentioned earlier, the Bollinger squeeze forms during periods of low volatility, when the market consolidates after a strong trend and is exploring opportunities for trend continuation or reversal. Financial markets thrive on empirical evidence, and the application of Bollinger Bandwidth in different sectors has provided just that. Success stories from trading in commodities like crude oil and precious metals like gold have shown remarkable outcomes following the integration of Bollinger Bandwidth indicators.
Because the bands are two standard deviations from the SMA, they show when prices are statistically high or low. Many traders consider the area near the upper band to be overbought territory—the price is poised to fall—and a potential resistance level where sellers may step in. Conversely, the area near the lower band is often seen as oversold—the price is poised to go up—and a potential support level where buyers could enter the market. In summary, Bollinger Bands are a versatile and essential tool in the trader’s toolkit.
In this example, the market just briefly poked above the higher Bollinger Bands ® and then immediately was rejected. Such a quick rejection move can be seen as a rejection of the bullish buying attempt. If such a rejection is followed by a strong bearish candle, this sequence may foreshadow more selling to come. Bollinger Bands can produce false signals, especially in choppy or sideways markets. Traders must exercise patience and discernment, avoiding the temptation to enter positions based on minor price fluctuations that don’t align with the overall trend. Bollinger Bands should be used in conjunction with an understanding of prevailing market conditions, such as trending, ranging, or volatile markets.
- Continual contact with the band or new lows below could indicate the bearish sentiment is strong and likely to continue.
- Keeping an eye on volume is essential to validate the strength of the trend.
- Bollinger Bands are a lagging indicator as a moving average is the central component of the calculation.
- For the astute trader seeking to optimize trading performance, Bollinger Bands Bandwidth stands as a pivotal volatility indicator.
- Rigidly adhering to a single trading strategy with Bollinger Bands can limit adaptability to changing market conditions.
- Master the powerful Bollinger Band squeeze strategy to identify high-probability breakout opportunities in any market.
Without getting too technical, the standard deviation measures the price fluctuation and the deviation from the average candle size. Historical price data might not always accurately reflect current market conditions. Traders should incorporate real-time data and news events into their decision-making process. Trading too frequently based on minor price movements within the Bollinger Bands can lead to high transaction costs and reduced profitability.
- I’ve found these settings particularly effective on 5-minute and 15-minute charts for forex and cryptocurrency pairs.
- The BB indicator is made up of three lines (bands) as shown in the image below.
- Strong trends that form after a breakout of a resistance or support level lead to a sudden expansion in volatility, causing the extreme bands to move apart.
- Thus, any time the closing price goes below or above the Bollinger bands, there are high chances for breakout or price reversion, and hence it can be used as a signal.
- Once you identify the squeeze, it’s time to watch for a breakout above the upper band, indicating an upward trend, or a break below the lower band, hinting at a downward trend.

In the analysis method recommended by developer John Bollinger, he suggested comparing the squeeze and max bandwidth positions over the past 125 days (125 candlesticks). If the squeeze levels are similar or have smaller compression values and the max bandwidth values are higher, it indicates a higher degree of accuracy. Remember that BandWidth is not a standard indicator of MT4/MT5, so you need to customise it before using it. In this example, the basic nature of Bollinger Bands is the oscillation between squeeze and expansion. Although price movements do not exhibit cyclical patterns, there are identifiable periods of volatility. In other words, periods of low volatility result in high volatility and vice versa.
It is often recommended that Bollinger Bands be used alongside other volatility indicators or technical tools to generate more accurate trading signals. Traders can use Bollinger Bands to trade a variety of strategies, but the most common is to buy when the price touches the lower band and sell when it hits the upper band. This strategy takes advantage of the fact that prices tend to revert back to the mean after periods of extreme volatility. Another way to use Bollinger Bands is to look for breakout opportunities. This can be done by watching for price breakouts above or below the upper or lower Bollinger Band.
It becomes a pillar of strategy validation, enabling a meticulous study of the band disparities during fluctuating market volatilities. Learn to classify price levels to enhance your trading setups and combine with indicators like Bollinger Bands. A complementary tool that uses Average True Range instead of standard deviation, resulting in smoother, less reactive channels with fewer whipsaws and false signals. Another powerful approach is the Bollinger Band squeeze strategy, which capitalizes on the market’s tendency to transition from low volatility to high volatility periods. Free bars are relatively rare occurrences that signal unusually high volatility and potential market exhaustion. While not guaranteed reversal signals, they often indicate that the current move may be overextended and due for at least a temporary reversal.
