What Are Bollinger Bands?
Bollinger Bands are a popular technical analysis tool used by traders and investors to analyze the volatility and potential price movements of a financial asset, such as stocks, currencies, or commodities. They were developed by John Bollinger in the 1980s and have since become widely used in the financial industry.
Bollinger Bands consist of three lines plotted on a price chart: a middle band, an upper band, and a lower band. The middle band is typically a simple moving average (SMA) of the asset’s price over a specified period. The upper and lower bands are calculated by adding and subtracting a specified number of standard deviations from the middle band.
The standard settings for Bollinger Bands use a 20-period SMA and a standard deviation of 2. However, traders can adjust these settings based on their preferences and the characteristics of the asset they are analyzing. For example, some traders may use a shorter or longer time period for the SMA and a different number of standard deviations.
The purpose of Bollinger Bands is to provide a visual representation of the volatility of the asset’s price. When the price is more volatile, the bands expand, and when the price is less volatile, the bands contract. The distance between the upper and lower bands indicates the range within which the price is expected to move. The narrower the bands, the tighter the range, suggesting lower volatility, while wider bands suggest higher volatility.
It’s important to note that Bollinger Bands are not foolproof and should be used in conjunction with other technical analysis tools and indicators to make informed trading decisions. Traders often combine Bollinger Bands with other indicators such as oscillators, trend lines, or candlestick patterns to gain a more comprehensive understanding of the market conditions and price trends. The following Figure shows an example of EURUSD with Bollinger bands applied:
The three close outside (TCO) technique assumes three consecutive close prices outside normality before detecting a reversal. The multiplier is 2.5 instead of 2.0. This increases the width of the bands and theoretically decreases the false signals. The trading conditions are as follows:
A bullish signal is generated whenever the market shapes three consecutive closes below the lower band.
A bearish signal is generated whenever the market shapes three consecutive closes above the upper band.
The following Figure shows an example of a bullish signal:
Bollinger bands work well in ranging markets. The following Figure shows a few signals:
