Breakouts above or below the Bollinger Bands are important events for a stock, since approximately 90% of price movements should occur between the bands. The distance between the bands, which is related to the volatility in a stock’s price over the previous 20 days, can also be informative but not conclusive on its own. Conversely, when the bands move far apart as volatility increases, it is expected that volatility will decrease into the future. However, there is no time constraint on when the change in volatility may occur from Bollinger Bands alone.
- Here, traders are looking to identify points where the moving averages of the MACD cross with the histogram displayed below the price chart.
- Avoid seeking overbought or oversold conditions when the bands are expanding.
- Most technical traders aim to profit from the strong uptrends before a reversal occurs.
- However, Bollinger Bands—especially when paired with other indicators such as chart pattern recognition tools—can help you make better trading decisions.
- In addition, Bollinger Bands are time frame agnostic, meaning they apply to all time period charts.
- You can use MACD to confirm Bollinger band breakouts or reversals, as well as to identify divergences or convergences between price and MACD.
Bollinger Bands are tools used in technical analysis to determine if a particular stock is overbought, oversold, or fairly valued. While they aren’t a perfect indicator of future stock movement, some traders report that Bollinger Bands can provide some clues to a stock’s next move. Double tops and double bottoms are essential technical analysis patterns used by traders.
What is a squeeze?
Yes, Bollinger Bands can be used in day trading to identify daily uptrends and reversals. Conversely, when the price breaks above the upper band, the trader following this strategy would consider opening a short position betting on a move back to the middle band. This Bollinger Bands trading strategy relies on the mean reversion of the price. Mean reversion expects that, if the price significantly deviates from the average, it will eventually revert back to the mean price.
What is the success rate of Bollinger Bands?
We tested the many ways to trade Bollinger Bands, but the research shows that none are more than 47% successful. This is because Bollinger Bands produce many false signals. One popular way to trade Bollinger Bands is to buy when the price crosses above the lower band and sell when it crosses below the upper band.
For example, during a strong trend, the trader is at risk for placing trades on the wrong side of the move since the indicator can suggest overbought or oversold signals too soon. To implement the Bollinger Band Breakout strategy, traders typically use the 20-day moving average and 2 standard deviation lines as their default settings. When the price breaks above the upper band, it is considered a bullish signal and traders look to enter a long position. Conversely, when the price breaks below the lower band, it is considered a bearish signal and traders look to enter a short position. Bollinger Bands divergence analysis can help you identify potential reversals by showing you when the price and the bands are out of sync.

These differences lead Keltner Channels to be smoother than bollinger bands since the standard deviation is more volatile than the average true range of a stock’s price. In addition, the exponential moving average is more sensitive to recent price changes than the simple moving average, so Keltner Channels respond to price action more quickly than Bollinger Bands. Mean reversion strategies can work well in range-bound markets, as prices can be seen noticeably bounce between the two bands. However, Bollinger Bands don’t always give accurate buy and sell signals.
