Bollinger Bands Technical Analysis and Bollinger Bands Forex Trading Signals

Developed by John Bollinger.

This indicator serves three primary functions:

• Provide a relative definition of high and low
• Show periods of high and low volatility
• Identify periods when prices are at extreme levels

Bollinger Bands do this by using standard deviation as a measure of volatility. Since standard deviation is a measure of volatility, the bands are self-adjusting; they widen during periods of higher volatility and contract during periods of lower volatility.

This indicator consist of 3 bands designed to encompass the majority of a trading instrument's price action. The middle band is a basis for the intermediate-term Forex trend, typically a 20-periods simple moving average, which also serves as the base for the upper and lower bands.

The upper band's and lower band's distance from the middle band is determined by volatility. Typically, the upper band is plotted +2 standard deviations above the middle band while the lower band is plotted -2 standard deviations below the middle band.

Interpretation

Bollingers are usually calculated using the trading instrument's prices and they have the following characteristics.

• Sharp price changes tend to occur after the bands tighten as volatility lessens, this is known as the Bollinger band squeeze.

• When prices move outside the bands a continuation of the current trend is implied.

• Bottoms and tops made outside the bands followed by bottoms and tops made inside the Bollinger Bands respectively, call for reversals in the Forex trend.

• A move that originates at one band tends to go all the way to the other band.

Trend Identification

This technical indicator is used as a trend following indicator since it shows the general direction of the Forex trend.

If the trend is upwards the middle and the lower bollinger provide excellent points for opening a buy trade, these levels act as support levels.
