Bollinger Bands emerged in the trading arena in 1983, courtesy of John Bollinger. Designed with a flexible framework and a visually intuitive appeal, they have since become a favored tool among traders for dissecting price action and understanding an asset’s volatility dynamics.
The trilogy of Bollinger bands
At its core, a Bollinger band comprises three integral lines:
1. The Middle Band:
Functioning as the foundation of the Bollinger Bands, the middle band is essentially a moving average, typically set to 20 periods.
2. The Upper Band:
Hovering above the middle band, the upper band is established by adding a specified number of standard deviations of price to the middle band, embodying the higher realms of price volatility.
3. The Lower Band:
Nestled below the middle band, the lower band is crafted by subtracting a certain number of standard deviations from the middle band, representing the lower vortex of price volatility.
Understanding Bollinger bands
The essence of Bollinger Bands lies in its intrinsic ability to adjust to market volatility. The distance between the upper and lower bands expands during periods of heightened volatility and contracts as volatility diminishes. This dynamic adjustment is orchestrated by the standard deviation parameter. It is set at 2 by default but can be modified to either amplify or diminish the sensitivity of the bands to market volatility.
Standard deviation may sound like a daunting mathematical term, but at its core, it is a straightforward concept. Think of it as a yardstick measuring how scattered or clustered a set of numbers is.
- When the Bollinger Bands are adjusted to encompass 1 standard deviation, it signifies that roughly 68% of the recent price moves are encapsulated within these upper and lower bands. In simpler terms, the majority of recent price activity is happening within this band range.
- Enhancing the range to 2 standard deviations captures about 95% of the recent price moves within the boundaries of the bands. This means that almost all recent price actions are contained within this wider span.
Use cases of Bollinger bands
Delving deep into the intricacies of standard deviations and its mathematical underpinnings might not be everyone’s cup of tea. Here are some practical applications of the Bollinger band that traders should focus on.
1. Detecting the power of trends
A sturdy uptrend or downtrend, when analyzed through the lens of Bollinger Bands, will consistently touch or approach the upper or lower band, respectively. This suggests the current market momentum and provides a signal for traders to consider buying and selling opportunities.
2. Recognizing strength in pullbacks
In the case of the bullish trend, if prices retract but remain above the middle band and then rally back to the upper band, this pattern indicates enduring strength in the asset’s movement, providing bullish trade opportunities. The opposite is true for bearish trends.
3. Identifying potential weaknesses of trends and reversals.
The reaction of price to Bollinger bands can also highlight a weakening current trend and an upcoming reversal. For instance, a strong uptrend should ideally steer clear of the lower band. Should the price gravitate towards this lower band during an uptrend, it serves as a cautionary signal, either highlighting a potential trend reversal or indicating waning strength in the asset.
Ultimately, Bollinger bands furnish traders with a tangible means to gauge market volatility, momentum, and potential trend reversals.
Bollinger bands expansion and squeeze
Bollinger Bands showcases market volatility through two main states: expansion and squeeze. Here’s a brief exploration of these states:
Expansion
During the expansion phase, the bands widen, indicating a trending market where prices are moving significantly upward or downward. It is advisable to avoid “range trading” strategies here and instead, ride the prevailing trend for potential gains.
Squeeze
The squeeze phase is marked by the narrowing of bands, signaling low market volatility and a likely forthcoming breakout. If candles break above the upper band, it usually suggests a continuing upward price movement. Conversely, candles breaking below the lower band often indicate a likely downward price trajectory.
Understanding these Bollinger Bands states assists traders in aligning their strategies with market conditions, potentially enhancing their trading outcomes.
Bollinger bands trading strategy
Bollinger Bands is a well-acknowledged technical analysis tool that offers traders a multi-layered perspective of market volatility by delineating upper and lower band boundaries surrounding a moving average. Here, we will discuss a Bollinger bands strategy that can be effectively deployed to recognize market ‘W-Bottoms’ and ‘M-Tops’, which are grounded on Arthur Merrill’s identified patterns. These patterns assist in pinpointing potential market turnarounds, thereby facilitating informed trading decisions.
Trading M-Tops
M-Tops are identified through Bollinger bands under a unique market scenario. An M-Top is initially flagged when a price high forms near or above the upper band, followed by a pullback towards the middle band or lower, leading to a new price high. Despite this high, if the price fails to close above the upper band and subsequently descends below the low of the previous pullback, an M-Top is established.
M-Tops, akin to a double-top chart pattern, signify a probable bearish market reversal. When prices fail to breach the upper band on a second high and decline below prior lows, it reflects a loss in momentum and a possible downward trajectory in price.
Trading W-Bottoms
Bollinger Bands assist in recognizing W-Bottoms under a specific condition: when a price low establishes either near or beneath the lower band, followed by a pullback towards the middle band or higher, culminating in a new low that still holds above the lower band.
A complete W-Bottom formation occurs when the price surges above the high of the first pullback, suggesting a probable transition toward a bullish market phase. This pattern essentially identifies a market scenario where a likely upward price movement in the near term.
The effective exploitation of W-Bottoms and M-Tops with Bollinger Bands can facilitate traders with discernible signals to either enter or exit positions as per the impending market direction. This strategy, grounded in meticulous pattern recognition, can thus serve as a substantial asset in a trader’s toolkit for navigating the financial markets.
