Bollinger Bands Technical Analysis Indicator Explained

bollinger bands

A stochastic indicator​ is another well-known technical analysis tool. Like, Stochastic indicators can help traders identify overbought and oversold levels.

By default, a 20-period SMA and 2 standard deviations are used to calculate the Bollinger Bands. However, since P&F moving averages are double smoothed, it may be necessary to shorten the moving average period when placing this overlay on a P&F chart. Settings can be adjusted to suit the characteristics of particular securities or trading styles. Bollinger recommends making small incremental adjustments to the standard deviation multiplier. Changing the number of periods for the moving average also affects the number of periods used to calculate the standard deviation.

Pros and Cons of Bollinger Bands

To fix this, a trader can look at the overall direction of the price and then only take trade signals that align them with the trend. For example, only take short positions when the upper band is tagged when the trend is down. If preferred, the lower band can still be used as an exit, but a new long position is not opened because that would mean going against the trend. Bollinger Bands can also be inclined to provide false signals. For example, a false breakout happens when an asset’s price passes through the trade entry point.
