The Basics of Bollinger Bands®

When the price touches or pushes through the upper band, this is often read as the security is overbought. This is because the asset is priced higher than its typical valuation range, indicating a potential reversal or slowdown in momentum. The upper band is found by adding two standard deviations to the center SMA line, while the lower band is calculated by subtracting two standard deviations from the center line. The bands automatically widen when price volatility increases and narrow when volatility goes down. As volatility increases, the standard deviation widens, which in turn expands the distance between the bands, signaling increased market volatility.

Thanks to his invention, bands became much more useful in the art of forecasting future prices through technical analysis. Bollinger Bands are a trend indicator that detect the volatility and dynamics of the price on the market.

Bollinger Bands is a versatile technical analysis tool that can provide greater clarity about market volatility and price trends. While it’s valuable for highlighting potential reversals, breakouts, and trend strengths, Bollinger Bands is usually more effective when used with other indicators and methods.

This strategy helps traders identify strong trends, periods of consolidation, and potential breakouts by observing price movements between these bands.

Whereas previously in the uptrend, the price was able to reach and trade outside the upper band, during the exhaustion, the price could not continue the trending phase. Again, I do not want to get too technical, but a small excursion is important to understand the approach of the Bollinger Bands® indicator ethereum guide and why it is so powerful. As the name implies, Bollinger Bands® are price channels (bands) that are plotted above and below the price action.

• The screenshot below shows the NZD/USD pair for a day and for 4 hours over the same time period.
• As you can see from the screenshot below, there was a squeeze in the Bollinger band for about six weeks before price broke out to higher levels during November of 2020.
• It’s worth noting the boundaries to these bands can be stretched to accommodate an injection of volatility, either to the upside or downside.
• However, you should confirm this with other indicators to avoid false signals or traps.

Instead, it can provide market traders with necessary information regarding the potential price volatility of an asset. Thus, it is best for you to develop your cryptocurrency trading strategies using Bollinger Bands, moving averages, the RSI, and oscillators.

Due to their dynamic nature, Bollinger Bands may be applied to various trading instruments, such as stocks, commodities, futures, and Forex. Bollinger Bands are calculated by adding and subtracting two standard deviations from a moving average. It is tempting to view the price touches of the lower or upper Bollinger Bands as absolute buy/sell signals. As John Bollinger acknowledged, “tags of the bands are just that, tags not signals.” A tag (or touch) of the upper Bollinger Band® is not in and of itself a sell signal. After the strong breakout from the contraction, the Bollinger Bands ® started widening immediately, signaling the strong trending price action. For investors using mean reversion strategies, the upper band can act as a price target in a ranging market.

To see how exactly they can be used in this way, we provide the following sample. To see how exactly they can be used in this way, we provide the following samples. Bollinger Bands were developed in the mid-1980s by John Bollinger for trading stocks. They emerged from the demand for adaptive trading bands and the observation that volatility was dynamic rather than static, as was widely regarded back then.

John Bollinger, a financial analyst, developed Bollinger Bands in the early 1980s. He was looking for a way to measure volatility in the stock market and developed a mathematical formula that used standard deviation to create the upper and lower bands. 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®. The reason for the second condition is to prevent the trend trader from being “wiggled out” of a trend by a quick move to the downside that snaps back to the “buy zone” at the end of the trading period. A contraction of the bands suggests that the market is experiencing less volatility. Price movements are more contained, and there may be less trading volume or market interest in the short term.

When the price breaks through the upper or lower band, the trader buys or sells the asset, respectively. 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®. Using the bands as overbought/oversold indicators relies on the concept of mean reversion of the price. Mean reversion assumes that, if the price deviates substantially from the mean or average, it eventually reverts back to the mean price. The Bollinger Bands ® indicator makes use of two concepts from statistics, the so-called confidence interval, and the normal distribution.
