It signals a trade but then moves back in the other direction, resulting in a losing trade. The standard Bollinger Bands formula uses a 20-day SMA for the middle line, while the other two are calculated based on volatility compared to the SMA. You can always modify this setting according to your trading preferences. For instance, some traders prefer to calculate the SMA based on a 10-day period only since they do not consider the data before being as relevant as the data from a more recent period.

Key Tips on How To Use Bollinger Bands® in Day Trading
Bollinger Bands consist of a simple moving average (SMA) and two bands above and below the SMA. Typically, the centerline is a 20-day moving average and the bands are two standard deviations. For example, a trader might use the RSI to confirm overbought or oversold conditions when the price touches the upper or lower Bollinger Bands. If the RSI also indicates an overbought condition when the price is at the upper band, this could strengthen the sell signal. Similarly, if the MACD shows a bullish crossover when the price bounces off the lower Bollinger Band, it could confirm a buy signal.
Bollinger Bands are a relatively simple trading tool and are incredibly popular with professional as well as at-home traders. However, using only the bands to trade is a risky strategy since the indicator focuses on price and volatility while ignoring various other relevant information. The bands contain a volatility indicator that measures a security’s relative high or low price compared to previous trades. Volatility is measured using standard deviation, which changes with increases or decreases in volatility. The bands widen when there is a price increase and narrow when there is a price decrease.
Markets
In practice, Bollinger Bands represent one of the most potent and reliable trading indicators in the world of technical analysis. This indicator is mainly used to interpret the strength of a trend and identify market tops or bottoms. Thus, the price should not last and should “revert back to the mean.” This generally means the 20-period simple moving average. A version of this strategy is discussed in the book Trade Like a Hedge Fund by James Altucher.

This persistence above the upper band might indicate strong buyer enthusiasm and signal that the trend is likely to continue. However, traders and investors often look to confirm this with other indicators or techniques. The three lines that make up Bollinger Bands are based on a security’s price moves. The center line is the intermediate-term trend and is typically a 20-day SMA of the closing prices.
What are the most used indicators in combination with Bollinger Bands?
As the price approaches and breaks the lower Bollinger Band, the underlying asset is considered “cheap.” That’s because, at the -x2 standard deviation, the price moves too far below the SMA. This may be a good opportunity to buy the asset (i.e., place long positions) and is generally not a good time to sell. Currently, the S&P 500 has moved from the lower part of the band to the middle. If stocks stay within the band, some traders might look for a buy signal if stocks cross above the moving average and the upper part of the band would become the new target. If stocks cross below the moving average, that would be a sell signal and the lower part of the band would become the new target.
The W-bottom pattern features a reversal where a downtrend is turning into an uptrend. In the chart below, notice how the Bollinger Bands are on a squeeze pattern and suddenly BOOM! So the formula above is telling us to add all the values of our periods and divide it by the amount of periods we’ll use. Also, note that the more you top crypto exchanges to use in 2020 increase the Standard Deviation Multiplier, the wider the bands will become as the measure becomes bigger.
However, traders often adjust these parameters based on the volatility of the asset and their individual trading strategies. Bollinger Bands are one of the most widely used and effective technical analysis tools for analysing volatility and identifying potential trading opportunities in financial markets. Introduced by John Bollinger in the 1980s, these bands have become essential for stock, forex, and cryptocurrency traders alike, offering valuable insights into market trends and volatility. This assumption is based on the statistical rule that about 95% of the data points will fall within two standard deviations of the mean for a normally distributed data set.
Strategies
Choosing two standard deviations provides a statistically significant measure of volatility while remaining practical for market analysis. The bands can adapt to changes in volatility, making them suitable for various market conditions. Bollinger Bands are a useful technical analysis tool that can help traders identify market trends, volatility levels, and overbought and oversold conditions. Bollinger Bands can help traders download bitcoin wallet generator ledger bitcoin fork identify potential price reversals by indicating when prices have reached or breached the upper or lower bands.
The middle band is the simple moving average (SMA) of a security’s closing price over a specified period. The default period is 20 days, but traders can customize the timeframe to suit their preferences or the characteristics of the asset being analyzed. Importantly, however, these conditions should not be taken as trading signals. The bands give no signs of when the change may take place or in which direction the price might move. According to Bollinger, it is necessary to look to other indicators to determine breakout direction.
Another simple yet effective trading method is fading stocks when they begin printing outside of the bands. Now, let’s take that one step further and apply a little candlestick analysis to this strategy. Other indicators such as support and resistance lines might 3 best white label providers 2025 prove beneficial when a trader decides whether or not to buy or sell in the direction of the breakout. Bollinger Bands can also help identify the direction of the prevailing trend. During an uptrend, prices tend to stay above the middle band (SMA), while in a downtrend, they remain below it.
Oppositely, the momentum is waving if the price pulls away from the outer band as the prevailing trend continues. From here, the price continues moving higher until valuations breach the upper band once again – the second downward arrow. On this second break, the trend has reached its end, which is apparent when prices ultimately fall below the 20-day SMA. All signals to close the long trade have been generated at this stage, and a trader is advised to collect profits.
