A Trader’s Guide","meta_descriptions":["Bollinger Bands help traders identify volatility, trends, and potential breakouts. Learn how Bollinger Bands work and how to apply them effectively."],"attrs_boilerpipe_text":"Bollinger Bands were created by American author and technical analyst, John Bollinger. They are a\npopular technical analysis\ntool used to identify market volatility, but they can also be used to generate potential buy and sell signals. They are made up of three lines:\nOne simple moving average (SMA) usually 20 days\/hours\/etc. (Middle band)\nThe SMA plus two standard deviations (Upper band)\nThe SMA minus two standard deviations (Lower band)\nThe unique feature of Bollinger bands is that they can be interpreted in several different ways. They can be used to create trading strategies for sideways markets or trending markets, but you need to be clear and consistent in the way you use them.\nFirstly, let’s look at the pros and cons of using Bollinger Bands.\nAdvantages:\nThey give a\nquick illustration of price volatility\nto help\ntraders assess current market conditions\n. They are dynamic since the bands expand when markets are volatile and contract when the price is moving sideways.\nThey can be used to\nidentify overbought and oversold market conditions\n. When the price approaches the upper band, the market may be considered overbought and when the price approaches the lower band, it indicates oversold levels.\nThey can\nprovide buy and sell signals in both trending and rangebound markets\n. Unlike many other indicators, Bollinger Band offer several different trading strategies, some applicable in range-bound markets and others in trending markets. (See the strategies below for more details).\nThey can be combined with other indicators such as RSI, stochastics or even price patterns to\nreinforce other trade signals\n.\nDisadvantages\nDespite their many advantages, Bollinger Bands are by no means infallible.\nThey can give\nfalse signals in trending markets\n. In strong uptrends\/downtrends, the price can track along one of the bands, leading to premature trade exits or failed counter-trend trades. Also, in very volatile markets, a sudden price spike can break out quickly, causing misleading signals.\nThey are seen as\nlagging indicators.\nSince they’re based on a moving average, some Bollinger Band strategies can give delayed trading signals.\nThe range of Bollinger Band trading strategies is an advantage but also a drawback, since\ntrading signals may be interpreted differently\n. For example, a touch of the lower band could indicate a breakout (sell signal) to some traders, but a reversal within a range (buy signal) to others.\nBollinger Band Trading Strategies\nWe’ve outlined three strategies below. Note that they are independent of each other and are each designed for different market conditions.\nRange trading strategy\nWhen the price is trading in a sideways range, it tends to oscillate up and down between the upper and lower bands. The assumption for this strategy to work is that the price will continue to trade sideways, continually reverting to mean at the moving average.\nA buy signal is given when the price dips below the lower band and then closes back above it, while a sell signal is given when the price breaks above the upper band and then closes back below it. Profits can be taken either at the moving average or at the opposite band.\nPinch or Squeeze Strategy\nThe assumption here is that, before big moves, the price will experience a particularly low volatility period which will “pinch” or “squeeze” the bands tightly together.\nWhen traders see this tightening, they can either set up a straddle trade (setting a buy order above the recent range and a sell order below) or wait for the breakout (above the top band or below the bottom band) and simply trade in that direction. They may also use other indicators to confirm the trade.\nTrend Reversal Strategy\nThis strategy works best when used in conjunction with chart patterns such as double tops and bottoms or head & shoulders.\nThe key feature here is that (in an uptrend) the price makes a high outside the upper band, followed by a subsequent high inside the upper band. The Bollinger Band is illustrating the fading upward momentum, while the chart pattern provides further evidence that a trend may be about to reverse. Once the 2\nnd\nhigh is confirmed inside the upper band, a sell signal is generated for the potential trend reversal.\nThe exact same process can be applied in downtrends.\nConclusion\nBollinger Bands are extremely versatile indicators, generating several different types of trading signals in sideways and trending markets. It is always sensible to confirm Bollinger Band signals with other indicators, such as RIS or MACD, and avoid blindly jumping into trades just because the price hits one of the bands.\nBollinger Bands are certainly worth considering as part of your trading strategy, but make sure to fit the correct strategy to the current market conditions.","attrs_markdown":"[![LAT\\_logo](https:\/\/www.lat.london\/wp-content\/uploads\/2025\/04\/LAT_logo.svg)](https:\/\/www.lat.london\/)   [![LAT\\_logo](https:\/\/www.lat.london\/wp-content\/uploads\/2025\/04\/LAT_logo.svg)](https:\/\/www.lat.london\/)   [![LAT\\_logo](https:\/\/www.lat.london\/wp-content\/uploads\/2025\/04\/LAT_logo.svg)](https:\/\/www.lat.london\/)\n\n[![](https:\/\/www.lat.london\/wp-content\/uploads\/2025\/04\/trust-p.webp)](https:\/\/www.trustpilot.com\/review\/lat.london)\n\n[Find out more](https:\/\/www.lat.london\/contact-us#find-out-more)\n\n- [Courses](https:\/\/www.lat.london\/courses\/)\n- [About Us](https:\/\/www.lat.london\/about-us\/)\n- [Resources](https:\/\/www.lat.london\/resource\/)\n\n**Explore**\n\n[Trading Courses](https:\/\/www.lat.london\/courses\/)\n\n- [Learn How to Trade](https:\/\/www.lat.london\/courses\/learn-how-to-trade\/)\n  - [Introduction to Financial Markets and Trading](https:\/\/www.lat.london\/courses\/learn-how-to-trade\/introduction-to-financial-markets-and-trading\/)   \n      Online \\| On Campus \\| Blended\n  - [Trading Skills Course](https:\/\/www.lat.london\/courses\/learn-how-to-trade\/trading-skills-course\/)   \n      Online \\| On Campus \\| Blended\n  - [Advanced Trading Course](https:\/\/www.lat.london\/courses\/learn-how-to-trade\/advanced-trading-course\/)   \n      Online \\| On Campus \\| Blended\n  - [Summer Trading School](https:\/\/www.lat.london\/courses\/learn-how-to-trade\/summer-trading-school\/)   \n      Online \\| On Campus \\| Blended\n- [Specialist Financial Courses](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/)\n  - [Cryptocurrency Course](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/cryptocurrency-course\/)   \n      Online\n  - [Options Trading Course](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/options-trading-course\/)   \n      Online\n  - [Equity Investing](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/equity-investing\/)   \n      Online\n  - [Investing in Fine Arts](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/investing-in-fine-arts\/)   \n      Online\n  - [Smart Money Concepts (SMC)](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/smart-money-concepts-smc\/)   \n      Online\n  - [Wealth Management](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/wealth-management\/)   \n      Online\n  - [Trading Psychology Workshop](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/trading-psychology-workshop\/)   \n      Online\n  - [Long Term Investing – How to build your own portfolio](https:\/\/www.lat.london\/courses\/specialist-financial-courses\/long-term-investing-using-macroeconomics\/)   \n      Online\n\n[Resources](https:\/\/www.lat.london\/resources\/)\n\n- [News & Blog](https:\/\/www.lat.london\/resources\/news-blog\/)\n- [LAT in the Press](https:\/\/www.lat.london\/resources\/lat-in-the-press\/)\n- [Download E-Books](https:\/\/www.lat.london\/resources\/ebooks\/)\n- [FAQs](https:\/\/www.lat.london\/faqs\/)\n\n[About Us](https:\/\/www.lat.london\/about-us\/) [Free Webinar](https:\/\/www.lat.london\/free-webinars\/) [Testimonials](https:\/\/www.lat.london\/testimonials\/) [Courses in Australasia](https:\/\/www.lat.london\/courses\/courses-in-australasia\/) [Refer a Friend](https:\/\/www.lat.london\/refer-a-friend\/) [Contact Us](https:\/\/www.lat.london\/contact-us\/)\n\n[![Home Icon](https:\/\/www.lat.london\/wp-content\/themes\/gus-lat\/assets\/images\/home-icon.svg) Home](https:\/\/www.lat.london\/)  [Resources](https:\/\/www.lat.london\/resource\/)[Blog](https:\/\/www.lat.london\/resource\/news-blog\/)[**Bollinger Bands**](https:\/\/www.lat.london\/resources\/blog\/bollinger-bands\/)\n\n# Bollinger Bands\n[Blog](https:\/\/www.lat.london\/category\/blog\/)\n\n\\|\n\nJune 26, 2025\n\nWritten by Paddy Osborn\n\n![Bollinger Bands trading indicator](https:\/\/www.lat.london\/wp-content\/uploads\/2025\/07\/Bollinger-bands.png?w=1024)\n\nBollinger Bands were created by American author and technical analyst, John Bollinger.

Boilerpipe Text	Bollinger Bands were created by American author and technical analyst, John Bollinger. They are a popular technical analysis tool used to identify market volatility, but they can also be used to generate potential buy and sell signals. They are made up of three lines: One simple moving average (SMA) usually 20 days/hours/etc. (Middle band) The SMA plus two standard deviations (Upper band) The SMA minus two standard deviations (Lower band) The unique feature of Bollinger bands is that they can be interpreted in several different ways. They can be used to create trading strategies for sideways markets or trending markets, but you need to be clear and consistent in the way you use them. Firstly, let’s look at the pros and cons of using Bollinger Bands. Advantages: They give a quick illustration of price volatility to help traders assess current market conditions . They are dynamic since the bands expand when markets are volatile and contract when the price is moving sideways. They can be used to identify overbought and oversold market conditions . When the price approaches the upper band, the market may be considered overbought and when the price approaches the lower band, it indicates oversold levels. They can provide buy and sell signals in both trending and rangebound markets . Unlike many other indicators, Bollinger Band offer several different trading strategies, some applicable in range-bound markets and others in trending markets. (See the strategies below for more details). They can be combined with other indicators such as RSI, stochastics or even price patterns to reinforce other trade signals . Disadvantages Despite their many advantages, Bollinger Bands are by no means infallible. They can give false signals in trending markets . In strong uptrends/downtrends, the price can track along one of the bands, leading to premature trade exits or failed counter-trend trades. Also, in very volatile markets, a sudden price spike can break out quickly, causing misleading signals. They are seen as lagging indicators. Since they’re based on a moving average, some Bollinger Band strategies can give delayed trading signals. The range of Bollinger Band trading strategies is an advantage but also a drawback, since trading signals may be interpreted differently . For example, a touch of the lower band could indicate a breakout (sell signal) to some traders, but a reversal within a range (buy signal) to others. Bollinger Band Trading Strategies We’ve outlined three strategies below. Note that they are independent of each other and are each designed for different market conditions. Range trading strategy When the price is trading in a sideways range, it tends to oscillate up and down between the upper and lower bands. The assumption for this strategy to work is that the price will continue to trade sideways, continually reverting to mean at the moving average. A buy signal is given when the price dips below the lower band and then closes back above it, while a sell signal is given when the price breaks above the upper band and then closes back below it. Profits can be taken either at the moving average or at the opposite band. Pinch or Squeeze Strategy The assumption here is that, before big moves, the price will experience a particularly low volatility period which will “pinch” or “squeeze” the bands tightly together. When traders see this tightening, they can either set up a straddle trade (setting a buy order above the recent range and a sell order below) or wait for the breakout (above the top band or below the bottom band) and simply trade in that direction. They may also use other indicators to confirm the trade. Trend Reversal Strategy This strategy works best when used in conjunction with chart patterns such as double tops and bottoms or head & shoulders. The key feature here is that (in an uptrend) the price makes a high outside the upper band, followed by a subsequent high inside the upper band. The Bollinger Band is illustrating the fading upward momentum, while the chart pattern provides further evidence that a trend may be about to reverse. Once the 2 nd high is confirmed inside the upper band, a sell signal is generated for the potential trend reversal. The exact same process can be applied in downtrends. Conclusion Bollinger Bands are extremely versatile indicators, generating several different types of trading signals in sideways and trending markets. It is always sensible to confirm Bollinger Band signals with other indicators, such as RIS or MACD, and avoid blindly jumping into trades just because the price hits one of the bands. Bollinger Bands are certainly worth considering as part of your trading strategy, but make sure to fit the correct strategy to the current market conditions.
