Traders also look for Bollinger ‘squeezes’ and Bollinger ‘bounces’, which are used as indicators for levels of support and resistance. Squeezes – when the upper and lower band contract toward the moving average – could show that there is about to be a breakout of the asset’s price. Conversely, bounces – which occur when the price movement hits the upper band and bounces back down – might be indicative of an upcoming retracement.

Are Bollinger Bands a good indicator?

Bollinger Bands ® are among the most reliable and potent trading indicators traders can choose from. They can be used to read the trend strength, to time entries during range markets and to find potential market tops.

The effectiveness of https://www.bigshotrading.info/blog/bollinger-bands-what-should-you-know-about-this-indicator/ varies from one market to another, and traders may need to adjust the settings even if they are trading the same security over a period of time. Many traders avoid trading during downtrends, other than looking for an opportunity to buy when the trend begins to change. The downtrend can last for short or long durations – either minutes, hours, weeks, days, months, or even years.

What are Bollinger Bands?

The key is just ensuring that the timeframe includes enough data and information to give you a clear overview of the market price. You don’t necessarily need to understand the Bollinger band formula, as it’s calculated for you in most trading platforms. But you do need to understand what the three bands on the chart are showing you. Chart 2 shows Nordstrom (JWN) with a W-Bottom in January-February 2010. First, the stock formed a reaction low in January (black arrow) and broke below the lower band. Third, the stock moved below its January low and held above the lower band.

  • Even though the stock moved above the upper band on an intraday basis, it did not CLOSE above the upper band.
  • I’m using the usual trailing offset as an exit for this strategy.
  • If preferred, the lower band can still be used as an exit, but a new long position is not opened because that would mean going against the trend.
  • It is also preferable to see the upper and lower band starting to widen in a breakout scenario.
  • The bands contain a volatility indicator that measures a security’s relative high or low price compared to previous trades.

However, if the trend is strong, the price can stay at the upper/lower Bollinger band or even beyond it without retracement for a prolonged period of time as we have learned from the previous passage. As a result, if you want to trade on the pullback from the upper or lower Bollinger band, you will need a confirmation of the market’s reversal from candlestick patterns or another indicator. https://www.bigshotrading.info/ are calculated using three lines drawn onto a price chart. The first line is the SMA of an assets’s price, usually within a 20-day period. The upper band is the SMA plus two standard deviations, while the lower band is the SMA minus two standard deviations.

What is Bollinger Band and how do you read it?

Bollinger Bands are a short-term trading tool that can help you decide when to make your move by assessing the relative strength—or momentum—of a stock investment. You can even apply them to the broad market. This indicator looks like an envelope that forms an upper and lower band around the price.

Bollinger Bands® can be a useful tool for traders for assessing the relative level of over- or under-sold position of a stock and provides them with insight on when to enter and exit a position. Certain aspects of Bollinger Bands®, such as the squeeze, work well for currency trading. Buying when stock prices cross below the lower Bollinger Band® often helps traders take advantage of oversold conditions and profit when the stock price moves back up toward the center moving-average line. They open a position only after a chart pattern or another technical analysis indicator confirms a specific price movement.

There is something else to discuss in this strategy that is often left out when talking about trading methods, and that is when to exit. So much attention is paid to the entry point for a trade, that the exit just seems to be taken for granted even though it is the most important part. A good exit strategy is a key to continued success and without it, traders tend to either take profits too early and leave money behind. See figure 6 above for a trading strategy in which involves trading the lower Bollinger Band once it reverses to the SMA and then scaling out on the way up to the upper Bollinger Band.

However, it’s worth remembering that it may take time to reach the opposite line. Therefore, in a conservative approach, a trader will wait for the price to break the middle line. The theory says that buyers prevail in the market when the price rises above the middle line; when the price falls below the middle line, sellers take control of the market. It doesn’t mean that a fall below the middle line will form a strong downtrend, but the price is expected to fall for at least some time. This indicator is intended for intraday use from the daily timeframe down to the 1 minute. Higher timeframe moving averages are step-lines as they use values from higher timeframes to calculate the moving average.
