How to Read Bollinger Bands For Beginners?

8 minutes read

Bollinger Bands is a widely used technical analysis tool created by John Bollinger. It is primarily used to analyze market volatility and identify potential trading opportunities. By understanding how to read Bollinger Bands, beginners can gain valuable insights into price movements and make informed trading decisions.


Bollinger Bands consist of three important components: a simple moving average (SMA) line in the middle, an upper band, and a lower band. The middle line represents the average price over a specific period, often 20 days. The upper and lower bands are calculated using standard deviations from the middle line. They typically sit two standard deviations away from the SMA.


When analyzing Bollinger Bands, it is crucial to observe the relationship between the price and the bands. Here are a few key aspects to consider:

  1. Squeeze: A squeeze occurs when the upper and lower bands come close together, indicating reduced volatility and potential consolidation in the market. Traders often anticipate a significant price movement following a squeeze.
  2. Breakout: When the price breaks out of the upper band, it suggests a bullish trend, indicating the possibility of further upward movement. Conversely, if the price breaks below the lower band, a bearish trend might be expected, signaling potential downward movement.
  3. Volatility: Widening bands imply increased volatility, while narrowing bands suggest declining volatility. This information can help traders assess the potential risk and profit potential of a particular trade.
  4. Support and Resistance: Bollinger Bands can serve as dynamic support and resistance levels. When the price touches the upper band, it may encounter resistance, and similarly, when it touches the lower band, it may find support. Traders can use these levels to set stop-loss and take-profit orders.
  5. Divergence: Divergence occurs when the price makes a new high or low, but the corresponding band fails to reach a new extreme. This situation may indicate a potential reversal in the price trend and can serve as a warning for traders.


While Bollinger Bands are a useful tool, it is important to rely on other indicators, chart patterns, and fundamental analysis to make well-rounded trading decisions. It is also advisable to practice using Bollinger Bands on historical price data and develop a strategy based on personal trading goals and risk tolerance.

What are the limitations of Bollinger Bands?

There are several limitations of Bollinger Bands:

  1. False signals: Bollinger Bands are prone to generate false signals, especially during periods of low volatility or erratic market conditions. Traders may get whipsawed if they act solely based on the signals provided by the bands.
  2. Lagging indicator: Bollinger Bands are calculated using past price data, which makes them lagging indicators. They may not react quickly to sudden price changes or new market trends, preventing timely entry or exit points.
  3. Insufficient in trending markets: Bollinger Bands work best in range-bound or sideways markets, where prices tend to oscillate between support and resistance levels. In trending markets, where prices move consistently in one direction, Bollinger Bands may not be as effective in identifying entry or exit points.
  4. Lack of contextual information: Bollinger Bands only consider price volatility and do not take into account other fundamental or technical factors that may impact the market. Therefore, they provide limited information about the overall market context, potentially leading to wrong interpretation or trading decisions.
  5. Parameters dependency: Bollinger Bands require users to select appropriate parameters, such as the period and standard deviation for calculating the bands. The choice of these parameters can significantly affect the performance and reliability of the bands, making them subjective and prone to personal bias.
  6. Over-reliance on middle band: Traders may mistakenly assume that prices will always move towards the middle band of the Bollinger Bands. While the middle band is considered a mean reversion point, it does not guarantee that prices will always revert to that level, leading to incorrect trading decisions.


How to set profit targets using Bollinger Bands?

Setting profit targets using Bollinger Bands involves identifying potential support or resistance levels based on the bands and using them as profit targets. Here are the steps to do so:

  1. Understand Bollinger Bands: Bollinger Bands consist of three lines: the middle band, which is a moving average, and an upper and lower band that are typically set two standard deviations away from the middle band. The upper and lower bands can help identify potential overbought or oversold levels.
  2. Identify a trending market: Look for a market that is trending either upwards or downwards. Bollinger Bands work best in trending markets.
  3. Determine the direction of the trend: Based on the price action and the position of the moving average, determine whether the trend is bullish (upward) or bearish (downward). This will help determine the profit target.
  4. Observe price action near the bands: When the price reaches the upper band, it may indicate overbought conditions. When the price reaches the lower band, it may indicate oversold conditions.
  5. Set profit targets based on support and resistance: Identify potential support levels near the upper band and resistance levels near the lower band. These can serve as profit targets. For example, in an uptrend, a profit target can be set near the upper band or a previous resistance level. In a downtrend, a profit target can be set near the lower band or a previous support level.
  6. Consider using other indicators: Bollinger Bands can be combined with other indicators or patterns to increase the probability of success. For example, you may want to confirm the potential support or resistance levels identified by Bollinger Bands with other technical analysis tools, such as trendlines, Fibonacci retracements, or candlestick patterns.
  7. Adjust profit targets based on market conditions: Market conditions can change, and it's essential to adjust profit targets accordingly. If the price continues to move in your favor, you can consider trailing your stop-loss order or adjusting your profit target to capture more significant gains.


Remember that Bollinger Bands are not foolproof and should be used in conjunction with other forms of technical analysis and risk management tools. It's crucial to backtest and practice these strategies in a simulated environment before implementing them with real money.


How to use Bollinger Bands in conjunction with support and resistance levels?

Bollinger Bands and support/resistance levels can be used together to enhance your trading strategy. Here are some ways to use them in conjunction:

  1. Confirmation of Support/Resistance Levels: When the price approaches a support or resistance level, look for a Bollinger Band squeeze or a narrow range between the bands. This can confirm that the support/resistance level is strong. Once the bands expand after the squeeze, it can signal a potential breakout or bounce.
  2. Bollinger Band Breakouts: When the price breaks above a resistance level or below a support level, wait for the Bollinger Bands to confirm the breakout. Look for the bands to widen and the price to move outside the upper or lower band. This can provide additional confirmation that the breakout is genuine.
  3. Volatility Squeeze: If the Bollinger Bands contract and narrow around a support or resistance level, it indicates decreased volatility. This can be a potential warning sign that a breakout may happen soon. Look for confirmation from other technical indicators before entering a trade.
  4. Bounce from Support/Resistance: If the price bounces off a support or resistance level and moves back towards the middle band of the Bollinger Bands, it can indicate a retracement or reversal. This can provide an opportunity to enter trades with the trend or counter-trend depending on the overall market conditions.


Remember to use proper risk management techniques, combine these signals with other technical indicators or price action analysis, and practice in a demo account before implementing them into your live trading strategy.
