A Bollinger Band® is a technical analysis tool defined by a set of trendlines. They are plotted as two standard deviations, both positively and negatively, away from a simple moving average (SMA) of a security’s price and can be adjusted to user preferences. The use of the standard deviation of the price as the defining variable in calculating Bollinger Bands is what allows them to serve as an indicator of volatility. Bollinger recommends increasing the multiplier to 2.1 when using a 50-day moving average and decreasing it to 1.9 when using a 10-day moving average. When the price of a security is highly volatile, the upper and lower bands will be far apart from one another, while the bands will narrow as price volatility decreases. In addition, many traders use Bollinger Bands to identify overbought and oversold conditions in the market.

About Bollinger bands

Since Bollinger Bands are a pure price indicator, you might want to consider combining them with volume indicators for even more depth and insight. Ultimately, there’s no indicator that guarantees you’ll always get in at the bottom or out at the top.

If you’re looking to go long when trading a squeeze, consider placing a buy entry point above the upper band.
