The importance of Bollinger Bands in the realm of technical analysis and trading cannot be overstated. Another strategy to use with Bollinger Bands® is called a squeeze strategy. A squeeze occurs when the price has been moving aggressively then starts moving sideways in a tight consolidation.

1. However, traders can customize the number of periods in the moving average as well as the number of deviations.
2. Trading turned flat in August and the 20-day SMA moved sideways.
3. The upper band is the moving average plus a multiple of the standard deviation, and the lower band is the moving average minus the same multiple of the standard deviation.
4. When the market is strongly bullish (or bearish), due to their inherent properties, the Bollinger Band envelope will widen dramatically.
5. Though, they can be a part of the signal generating decision process.

Remember that while Bollinger Bands are a valuable tool, they don’t guarantee profits, and successful trading requires discipline and continuous learning. Bollinger Bands have default settings, but these settings may not be optimal for all assets or timeframes. Traders should adjust the parameters (e.g., the moving average period and standard deviation multiplier) to better suit the asset and trading style they are using. As with most technical indicators, values for the look-back period and the number of standard deviations can be modified to fit the characteristics of a particular asset or trading style.

To help remedy this, a trader can look at the overall direction of price and then only take trade signals that align the trader with the trend. For example, if the trend is down, only take short positions when the upper band is tagged. The lower band can still be used as an exit if desired, but https://www.topforexnews.org/brokers/tradeview-markets-service-review/ a new long position is not opened since that would mean going against the trend. Developed by John Bollinger, Bollinger Bands® are volatility bands placed above and below a moving average. Volatility is based on the standard deviation, which changes as volatility increases and decreases.

In the 2001 chart of Microsoft (MSFT) below, you can see the trend reversed to an uptrend in the early part of January. Before the price action crossed over the centerline, the stock price moved from $20 to $24 and then on to between $24 and $25 before some traders would have confirmation of this trend reversal. The breakout is not a trading signal and many investors mistake that when the price hits or exceeds one of the bands as a signal to buy or sell. Breakouts provide no clue as to the direction and extent of future price movement.

But remember, since volatility is mean-reverting, the bands will probably expand, signaling a potential for an explosive move. A simple way to spot a squeeze is to identify when the bands are the narrowest they have been for the last six months. An upside breakout might be confirmed with a price close above the resistance trend line as well as above the upper Bollinger Band.

A common approach when using Bollinger Bands® is to identify overbought or oversold market conditions. When the price of the asset breaks below the lower band of the Bollinger Bands®, prices have perhaps fallen too much and are due to bounce. On the other hand, when price breaks above the upper band, the market is perhaps overbought and due for a pullback. One of the more common calculations uses a 20-day simple moving average (SMA) for the middle band.

Importance of Bollinger Bands

In fact, Bollinger Bands® should be used with other non-correlated indicators. Doing so may give you additional market signals that are much more direct. Another drawback is that they are calculated using a simple moving average. That’s because older price data is weighted in the same way as recent data.

Overlooking Market Conditions

From mid-January until early May, Monsanto closed below the lower band at least five times. Notice that the stock did not close above the upper band once during this period. The support break and initial close below the lower band signaled a downtrend. As such, the 10-period Commodity Channel Index (CCI) was used to identify short-term overbought situations. A move back below +100 signals a resumption of the downtrend (red arrows). Bollinger bands help determine whether prices are high or low on a relative basis.

Perhaps a more useful way to trade with Bollinger Bands® is to use them to gauge trends.

IG’s guide on how to use Bollinger Bands in trading

Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can determine if prices are relatively high or low. According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant. Technically, prices are relatively high when they’re above the upper band and relatively low when below the lower band. However, “relatively high” should not be regarded as bearish or a sell signal. Likewise, “relatively low” should not be considered bullish or a buy signal.

The highs and lows of a consolidation may be marked with trend lines. A price moves above the high of the consolidation would consider an upside breakout, while a price https://www.forex-world.net/blog/white-label-program/ close below the low of the consolidation would consider a downside breakout. The Bollinger Bands can now be used as a filter for these breakout trade scenarios.

From a practical application perspective, Bollinger Bands are extremely flexible. For example, they can be helpful in diagnosing technical patterns like W bottoms and M tops, as well as some Bollinger Band specific patterns like the Squeeze and the Head Fake, which have become very popular with traders. Indeed, there are potentially as many uses as there are traders.

Further, the width of the band can be an indicator of its volatility (narrower bands indicate less volatility while wider ones indicate higher volatility). The reason why the upper and lower Bollinger bands are two standard deviations away from the moving average is that this makes an envelope around the closing price and contains the majority of the price action. Statistically, two standard deviations include 95% of price movement. Thus, any time the closing price goes below or above the Bollinger bands, there are high chances for breakout or price reversion, and hence it can be used as a signal. The chart thus expresses arbitrary choices or assumptions of the user, and is not strictly about the price data alone. Bollinger Bands® is not a standalone trading system but just one indicator designed to provide traders with information regarding price volatility.

John Bollinger suggests using them with two or three other non-correlated indicators that provide more direct market signals and indicators based on different types of data. Some of his favored technical techniques are moving average divergence/convergence Is peloton a public company (MACD), on-balance volume, and relative strength index (RSI). Such techniques usually require the sample to be independent and identically distributed, which is not the case for a time series like security prices.
