Bollinger Bands Indicator: What is it? How to use it? Insights

Yes, it is possible to combine Bollinger Bands and the Relative Strength Index (RSI). RSI provides an additional confirmation regarding the state of the price of a stock, if it is in an overbought or oversold state. Both the indicators, if combined, can nurture a better understanding of the current situation and give better clues about the future of the stock. In the image uploaded above, the first few purple boxes represent how the lower bollinger band managed to act as a strong support and the price of the stock bounced from that level. The arrow represents the breakdown of the lower band indicating trend shiftment towards downside. The purpose of Bollinger Bands is also to provide a relative definition of the high and low prices of a market.

How to interpret Bollinger Bands?

Volatility is shown on the basis of the standard deviation for a particular security. Such techniques usually require the sample to be independent and identically distributed, which is not the case for a time series like security prices. Various studies of the effectiveness of the Bollinger Band strategy have been performed with mixed results. The lexatrade review authors did, however, find that a simple reversal of the strategy (“contrarian Bollinger Band”) produced positive returns in a variety of markets.

• It helps identify the “calm before the storm” and signs of a trend change.
• An important requirement for the correct use of the indicator is sufficient price activity and calibration of the parameter settings based on the history of its movement.
• Reversals occur when the price of an asset changes direction and moves in the opposite direction of the previous trend.
• You want to get in on the volatility if you’re using penny stock strategies.
• A price move that starts at the upper band and continues to push outside of it can signal one, especially if there’s been an increase in trading volume.
• However, traders often adjust these parameters based on the volatility of the asset and their individual trading strategies.

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. For investors using mean reversion strategies, the upper band can act as a price target in a ranging market. While the settings can be adjusted based on your strategy, most times, you would use a 20-day SMA and two standard deviations. Bollinger Bands are a reliable and effective tool for measuring market volatility.

This strategy often incorporates other indicators for confirmation and is popular for its ability to adapt to different market volatility levels. Bollinger Bands can be a powerful technical tool for stock market traders. By combining a moving average with a measure of price volatility, Bollinger Bands offer insights into potential price reversals, overbought or oversold conditions, and market volatility. Vice versa for the short position around the upper bollinger bands and placing a safe stop loss a few points above the upper band to ride a short trade. Fundamental analysis examines market news, economic/social/political forces, and earnings data to predict how an asset’s price will move.

Breakout Trading

A trader can visually identify a squeeze when the upper and lower bands get closer together, constricting the moving average. A squeeze is a sign of decreased volatility and is considered by investors as a possible sign of future increased volatility and potential trading opportunities. Conversely, the further away the bands move from each other, the more likely the chance of a decline in volatility and the more significant the possibility of exiting a trade.

Relative Strength Index vs Commodity Channel Index: Which is Better?

For such reasons, it is incorrect to assume that the long-term percentage of the data that will be observed in the future outside fusion markets: a 2020 review the Bollinger Bands range will always be constrained to a certain amount. Therefore, traders may not get signals until the price movement is already underway. They are merely one indicator designed to provide traders with data regarding price volatility. John Bollinger suggests using them in conjunction with other non-correlated indicators that provide more direct market signals.

Upper resistance and lower support lines are first drawn and then extrapolated to form channels within which the trader expects prices to be contained. As long as prices do not move out of this channel, the trader can be reasonably confident that prices are moving as expected.

In simple terms, we would say that 95% of all the price action happens in between 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. 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. If you are not interested in the underlying principles of the Bollinger Bands® indicator, you can skip ahead to the next section where we cover some common use cases.

Calculation of Bollinger Bands

The overbought and oversold conditions are identified using Bollinger Bands, to generate buy and sell signals, when the prices of securities touch the upper and lower bands. This ultimately Indicates that the security is due for a price correction or reversal. Bollinger bands is a technical analysis tool used by traders to identify the volatility of securities in the market. Bollinger bands was developed in the 1980s and since then it is one of the most popular technical analysis tools used by traders. One of the main limitations is that it shouldn’t be used as a standalone tool.

• When considering which stocks to buy or sell, you should use the approach that you’re most comfortable with.
• 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.
• The book acts as a guide for investors in order to understand and effectively utilise the Bollinger Bands in various market scenarios.
• After the bands have narrowed for some time, they are signaling that a period of increased volatility lies ahead.
• The Bollinger Bands is a chart overlay indicator, which means that the bands are projected over the price of the security.

Bollinger Bands Divergence

The upper Bollinger bands can also identify potential trend breakouts and reversals. A bullish breakout is indicated when the price breaks above the upper band in technical analysis. The movement of the price from one band to another band signals a potential trend reversal in the market price of the stock. This setup is versatile, providing a balance between sensitivity and reliability for many markets and time frames.

We have mentioned how the standard Bollinger Band uses a 20-days SMA and 2 standard deviations. For example, a more active trader may want to utilize a Bollinger Band which deviates less and/or utilizes a lesser number of periods (thus generating more signals for the trader). Bollinger bands also have their advantages and disadvantages just like any other indicator or tool used for technical analysis.

So far, we have seen that breakouts from contractions can foreshadow new trending phases and a strong push outside of the Bollinger Bands ® can be seen as a trend confirmation. But the Bollinger Bands ® indicator what is a pipette in forex can also be used for trend-following pullback trading. Once a trend is on its way, traders typically wait for the price to show a pullback phase. A pullback is a short pause in the trending market where the price moves sideways or makes a short move into the opposite trend direction.

One of the main points of Bollinger Bands as a technical analysis indicator is to track how far away are the prices from the SMA in order to determine if an asset is overbought or oversold. Bollinger Bands are composed of a simple moving average and two standard deviation lines which we know as the upper and lower bands. In the 1980s, John Bollinger, a long-time technician of the markets, developed the technique of using a moving average with two trading bands above and below it. Unlike a percentage calculation from a normal moving average, Bollinger Bands® simply add and subtract a standard deviation calculation. Upper Bollinger Bands in technical analysis are used with other indicators in order to confirm trading signals and take important decisions. This is denoted by the upper and lower lines or bands as the standard deviation is a measure of volatility.

The distance between the upper and lower lines is typically a fixed percentage or a specific number of points. Bollinger Bands are envelopes plotted at a standard deviation level above and below a simple moving average of the price. The distance of the bands is based on the standard deviation, and they adjust to volatility swings in the underlying price.

One next calculates the standard deviation of the prices over the same number of periods. The standard deviation is a measure of volatility and is calculated as the square root of the variance of the prices. The outer and inner bands are created by calculating the moving average of an asset over a specific period and adding and subtracting a specific multiple of the standard deviation from the moving average. Bollinger Bands were developed by John Bollinger with the purpose of giving investors a tool to identify the volatility of assets with high probability. The upper and lower bands are used to determine the volatility(degree of price variation) of the market. Scalpers using Bollinger Bands configure them with the default settings of a 20 Period Simple Moving Average and a Standard Deviation Multiplier of 2.
