Traders can establish long positions when the price breaks above the upper band and short positions when it breaks below the lower band. To manage risk, traders can place stop-loss orders just below or above the breakout point. That line shows the SMA over time, and the Bollinger Bands are then placed above and below it by calculating the standard deviation of the security’s price along each data point. The standard deviation measures how much a security’s price deviates from its average, reflecting price volatility against its SMA, representing price volatility.

Setting Up Bollinger Bands in your trading platform

As you can see below, the bands expand as volatility increases and contract as the volatility decreases. Choosing the right trading journal is essential for traders wanting to analyze performance, refine programmer’s life strategies, and improve consistency. After the push outside the lower Bollinger Bands ®, the trend continued to the downside and the price stayed very close to the lower band. Strong continuation pushes below the lower band confirm the trend direction.

Next, the price moved all the way into the opposite Bollinger Bands ® and started trading outside the lower band. The price showed extreme strength and the price was even able to close outside the lower band. As we have learned, most of the candlesticks will fall inside the Bollinger Bands ®. In the screenshot below, the price first showed a Bollinger Bands ® exhaustion. The exhaustion is confirmed when the price fails to reach the upper Bollinger Bands ® in an uptrend. 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.

• If you don’t know, technical analysis is a discipline that aims at forecasting future prices using only past price behaviour (looking at charts with old prices).
• 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.
• In other words, if the price goes up and nears the top band but doesn’t cross it, there’s a good chance it will bounce down, which signals a sell action.
• If the S&P 500 were to move lower and there is a breakthrough of the lower part of the band, that would generate a sell signal by breaking through a support level.
• If you’re freaking out because you’re not familiar with standard deviations.
• 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.

Bollinger Bands are just providing you entry and exit points that computer network engineer job description duties and responsibilities software development you need to know how to match with the current trend. In the chart below, notice how the Bollinger Bands are on a squeeze pattern and suddenly BOOM! We are starting with the Bollinger Bands ® contraction because a contraction often foreshadows a trend change or a trend continuation and is, therefore, the first important signal. 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.

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. Shorter timeframes may generate more frequent signals but are also more susceptible to false signals and market noise. Conversely, longer timeframes may produce fewer signals but are generally more reliable. A lot of new traders tend to gaze at Bollinger Bands and make the general assumption that when the price hits the upper band, it’s a sell signal and when the price hit’s the lower band, it’s a buy signal.

Customizing Bollinger Bands Settings

Remember that the RSI is a leading momentum indicator while the Bollinger Bands is a lagging indicator, which means that combining them helps us spot reversals better. Finally, the Bollinger Bands ® started contracting and the bands narrowed when the price started moving sideways with smaller candlesticks. A bullish trend change might now be underway when the price starts pushing into the upper Bollinger Bands ®.

The Bollinger Band Squeeze is a trading strategy that takes advantage of periods of low volatility to anticipate potential price best countries to outsource software development in 2022 breakouts. When the bands contract and move closer together, the market is in a low-volatility phase, often preceding significant price movements. Traders can enter a long or short position when the bands begin to expand, anticipating the subsequent price movement. These alternative moving averages give more weight to recent price data, making them more responsive to changes in price action. The bands adjust to volatility, providing a dynamic perspective on price action.

Trends with Bollinger Bands can vary based on the asset and trading strategy, lasting anywhere from minutes to years. To fully grasp the potential of Bollinger Bands, traders can study real-life examples and case studies of successful Bollinger Bands applications. These examples can provide insights into how Bollinger Bands work in various market conditions and how traders have used them to generate profitable trading signals. The Bollinger Band Walk strategy occurs when the price “walks” along the upper or lower band during a strong trend, offering traders multiple entry and exit points. In an uptrend, traders can enter long positions when the price bounces off the upper band and exit when it moves below the middle band. In a downtrend, traders can enter short positions when the price bounces off the lower band and exit when it moves above the middle band.

Spotting Reversals

Bollinger bands are used to measure volatility and define potential price channels or trends. When prices move outside the bands, it can indicate that a new trend is beginning or that prices have become overextended. If the upper and lower bands are 2 standard deviations, this means that about 95% of price moves that have occurred recently are CONTAINED  within these bands. The upper and lower bands, by default, represent two standard deviations above and below the middle line (moving average). The SMA line doesn’t always stay between the Bollinger Bands — it can also move above or below the bands.

Analyzing Market Conditions

We introduce people to the world of trading currencies, both fiat and crypto, through our non-drowsy educational content and tools. We’re also a community of traders that support each other on our daily trading journey. You can try out different standard deviations for the bands once you become more familiar with how they work.

The setting defaults to a 20-day period for the SMA and sets the upper and lower lines to (x2) standard deviations away. This way, these bands can capture at least 85% of the price data moving between them for that period. The Bollinger Bands indicator was invented by the renowned trader and financial analyst John Bollinger in the early 1980s. They essentially help you identify possible price reversals by determining overbought and oversold levels using standard deviation. This is because trending markets can sometimes ride the bands for a long time and suddenly stop existing trades using the cheap/expensive model. That’s why you should always use another indicator, such as the Relative Strength Index (RSI), to confirm the “squeeze” and “bounce” of both upper and lower bands.

The standard deviation is a measure of price volatility, and it typically uses a 20-period lookback window. A common multiple is 2, so the upper band would be the 20-day SMA plus two times the 20-day standard deviation of price. 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.

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. As the name implies, Bollinger Bands® are price channels (bands) that are plotted above and below the price action. If you’re freaking out because you’re not familiar with standard deviations. Just like in trading, certain technical indicators are best used for particular environments or situations.

Bollinger Bands help traders understand whether a security’s price is relatively high or low so that they might make trades based on trends. Bollinger Bands can indicate uptrends and downtrends as well as possible upcoming price reversals. This context can help traders understand how Bollinger Bands interact with different market environments and learn to adapt their trading strategies accordingly.
