Bollinger Bands Indicator

The Bollinger Bands indicator is a popular technical indicator that helps traders identify potential overbought or oversold conditions in the market. Developed by John Bollinger in the 1980s, Bollinger Bands are a volatility indicator that consists of a simple moving average and two standard deviation lines, one above and one below the moving average.

Calculation of Bollinger Bands

The Bollinger Bands indicator is calculated using the following formula:

Middle Band = Simple moving average (SMA)
Upper Band = SMA + (Standard deviation x 2)
Lower Band = SMA - (Standard deviation x 2)

Typically, the middle band is a 20-day simple moving average, and the standard deviation is calculated on the same 20-day period. However, traders can use different periods and standard deviation calculations to suit their particular trading style and market.

Interpreting the Signals

Bollinger Bands are used to identify potential overbought or oversold conditions in the market. When the price is trading close to the upper band, it is considered overbought, and when the price is trading close to the lower band, it is considered oversold. Traders can use this information to enter or exit trades or to determine whether to hold onto a current position.

Additionally, Bollinger Bands can also be used to identify volatility in the market. When the bands are wide apart, it indicates high volatility, and when the bands are close together, it indicates low volatility. This information can be useful for traders who prefer to trade in markets with higher volatility.

Another signal that can be generated by Bollinger Bands is a breakout. When the price breaks above or below the upper or lower band, it can indicate a potential trend reversal or continuation. Traders can use this information to enter or exit trades or to determine whether to hold onto a current position.
