There are essentially three Bollinger Bands strategies traders can use in their technical analysis. The second, called Breakout Strategy focuses on identifying potential reversals or trend continuations when the price gets outside two bands. Finally, the third method called Squeeze can be helpful in forecasting market volatility and consequently the timing of opening and closing trades.
- When the lower band turns back up, it can be a signal that the move higher might be over, at least for a while.
- Moreover, for both the middle band and calculation of standard deviation usually, the same period is used.
- For instance, a 20-period SMA is typically used as the default, but shorter timeframes may require a smaller SMA length, while longer timeframes may require a larger SMA length.
- To use this strategy, you need first to set up your chart.
This strategy necessitates a basic understanding of price action. Some traders find that this extra pair of lines helps them identify trends. They can also act as the points the stock trades between — like support and resistance lines. It helps them make informed predictions on its future direction. The standard deviation lines show you where the stock will most likely trade between.
Do Bollinger Bands work?
After the rally commences, the price attempts to retest the most recent lows that have been set to challenge the vigor of the buying pressure that came in at that bottom. As we all know, every strategy has its drawbacks and this one is definitely no exception. In the following examples, we’ll demonstrate the limitations of this strategy and what can happen when things do not work out as planned.
A Bollinger Band®, as we mentioned above, is a tool used in technical analysis. It is defined by a series of lines that are plotted two standard deviations—both positively and negatively—away from the simple moving average (SMA) of the price of a security. Bollinger Bands typically use a 20-period moving average, where the “period” could be 5 minutes, an hour or a day. By default, the upper and lower bands are set two standard deviations above and below the moving average.
Signaling the starts or the ends of trends
However, a common starting point is a 20-period SMA and 1 or 1.5 standard deviations. To read a Bollinger Bands chart, look at the price action in relation to the upper and lower bands. If the price is closed above the upper band, it indicates an overbought condition. Conversely, if the price closes below the lower band, it signals an oversold condition. It’s also important to note that when prices hit either of these bands, they are likely to reverse direction.

As a result, prices rising above the upper band indicate overbought markets and generate a sell signal. Conversely, prices falling below the lower band indicate oversold markets and issue a buy signal. Defined as a degree of positive or negative price variation over time, volatility is generally measured through standard deviation.
A Winning Bollinger Bands Trading Strategy
Additionally, Bollinger Bands can help you identify price action trends and potential support and resistance levels. Traders can customize Bollinger Bands to suit different trading styles and preferences. Traders can adjust the lookback period for the simple moving average (SMA) and the number of standard deviations used for calculating the upper and lower bands. For example, a more extended lookback period will result in a smoother SMA, while a shorter period will make the SMA more sensitive to recent price changes.
The bands do not indicate when the change may take place or in which direction the price could move. Since Keltner Channels use average true range rather than standard deviation, it is common to see more buy and sell signals generated in Keltner Channels than when using Bollinger Bands®. In the chart below, we see that a fade-trader using Bollinger Band® “bands” will be able to quickly diagnose the first hint of trend weakness. Having seen prices fall out of the trend channel, the fader may decide to make classic use of Bollinger Bands® by shorting the next tag of the upper Bollinger Band®. If memory serves me correctly, Bollinger Bands, moving averages, and volume were my first indicators as a beginner trader. A much easier way of doing this is to use the Bollinger Bands width.
During the selloff there was no way to know when it would end. A breakout above or below the bands occurs when there is a major event. Most people make a mistake when they find the breakout, they believe that price breaking the bands or exceeding one band is signal for buy or sell. Breakouts don’t provide any clue for the direction of future price movement. As we discussed, when the bands get close together as shown in the image –it is called a squeeze. Whenever traders find the squeeze, it is considered as a potential signal of an increase in volatility in the future and traders can get trading opportunities.

They will then place their trades in accordance with the new price trends that emerge when the asset’s price breaks out, and market volatility is present. Various studies of the effectiveness of the Bollinger Band strategy have been performed with mixed results.

Finally, the long-term trendline is breached to the downside in the first week of February.

When the bands widen, it indicates increased volatility; when they contract, it signifies decreasing volatility. This information can help traders and investors prepare for potential price movements and identify appropriate entry and exit points. Another trading strategy is to predict when https://1investing.in/ a squeeze will begin. Using daily charts, the idea is that when the indicator reaches its lowest level in 6 months, volatility will rise. This relates to the tightening of the bands we mentioned earlier. The Bollinger Band indicator’s squeezing action frequently foreshadows a large move.

The middle line can represent areas of support on pullbacks when the stock is riding the bands. You could even increase your position in the stock when the price pulls back to the middle line. Notice how the volume exploded on the breakout and the price began to trend outside of the bands; these can be hugely profitable setups if you give them room to fly. In this post we’ll provide you with a solid foundation on the bands, plus six trading strategies you can test to see which works best for your trading style.

A stock may trade for long periods in a trend, albeit with some volatility from time to time. To better see the trend, traders use the moving average to filter the price action. This way, they can gather important information about how the market is moving. For example, after a sharp rise or fall in the trend, the market may consolidate, trading in a narrow fashion and crisscrossing above and below the moving average.
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 a price that has touched the lower band and wait to see where the next low occurs. In the second example that we will present, we will witness the Double Bollinger Bands’ trading strategy’s efficiency.
How Are Bollinger Bands Calculated?
According to Bollinger, there’s one pattern that raises more questions than any other aspect of Bollinger Bands®. He calls it “the Squeeze.” As he puts it, his bands, “are driven by volatility, and the Squeeze is a pure reflection of that volatility.” Additionally, you can also use Bollinger Bands as one indicator that can help your trading journey in the cryptocurrency market. These are but a few of the great methods for trading with bands. I just struggled to find any real thought leaders outside of John.
When the price moves close to either band, this can be seen as an overbought and oversold signal depending on whether the price is near the upper or lower band. Traders can use Bollinger Bands to trade reversals or continuation patterns depending on the price position relative to the bands. During a period of low volatility, the bands come closer constricting the moving average. Bollinger bands are driven by volatility and “the squeeze” is a pure reflection of that volatility. When volatility falls to historically low levels, the squeeze is on.

At the end of the day, bands are a means for measuring volatility. So, it’s not something you can just pick up and use for buy and sell signals. Just as a reminder, the middle band is set as a 20-period simple moving average in many charting applications. Just like in the previous example, there was still selling pressure on the stock. While everyone else was selling, the strategy calls for a buy. The break of the lower Bollinger Band® signaled an oversold condition.
