The Bollinger Band Squeeze is a popular concept in technical analysis that traders use to identify periods of low volatility and anticipate potential breakouts. Named after John Bollinger, who introduced Bollinger Bands in the 1980s, this technique revolves around the behavior of the bands themselves—specifically, when the bands contract or “squeeze” closer together.

Bollinger Bands consist of three lines plotted on a price chart: a simple moving average (typically 20 periods) in the middle, and two outer bands that are standard deviations away from the moving average. These outer bands expand and contract based on the volatility of the underlying asset. The formula for Bollinger Bands is:

Middle Band = 20-period Simple Moving Average (SMA)
Upper Band = Middle Band + (2 × Standard Deviation)
Lower Band = Middle Band − (2 × Standard Deviation)

When the bands narrow, it indicates that the price is experiencing low volatility. This contraction phase is what traders call the “Bollinger Band Squeeze.” The squeeze itself doesn’t indicate the direction of the upcoming move, but it does signal that a significant price move may be imminent because volatility tends to revert to the mean after periods of calm.

A classic real-life example of a Bollinger Band Squeeze occurred with the EUR/USD currency pair in mid-2020. During a few weeks in June, the Bollinger Bands tightened significantly as the pair traded within a narrow range. This low-volatility environment hinted at a potential breakout. Shortly after, the pair surged sharply higher following a breakout above the upper band, confirming the squeeze setup and offering a profitable trading opportunity for those who anticipated the move.

One common mistake traders make when using the Bollinger Band Squeeze is assuming that every squeeze results in a strong breakout. Not all squeezes lead to powerful moves; sometimes, the price may break out only briefly or reverse soon after. Therefore, it’s crucial to combine the squeeze with other indicators or confirmation tools, such as volume analysis, momentum oscillators like RSI (Relative Strength Index), or even price action patterns, to improve the reliability of trade signals.

Another misconception is to treat the squeeze as a directional signal. The bands only indicate that volatility is low and a sharp move may be coming, but they don’t predict whether the breakout will be upward or downward. Traders often look for a close above the upper band or below the lower band to confirm the breakout direction before entering a trade.

In summary, the Bollinger Band Squeeze is a valuable volatility indicator that signals potential breakouts after periods of low price movement. However, it should not be used in isolation. Combining it with other technical tools and waiting for confirmation improves the chances of successful trades. Being aware of common pitfalls, such as expecting every squeeze to lead to a breakout or misreading the bands as directional signals, can help traders make better decisions.
