The upper and lower bands are usually set at a certain number of standard deviations from the moving average, with two standard deviations being the most commonly used value.

When the price moves outside the bands, it is considered overbought (if it moves above the upper band) or oversold (if it moves below the lower band).

Bollinger Band Strategies

Bollinger Band Strategies

There are many different types of strategies that traders use with Bollinger Bands.

Here are some examples:

Momentum strategy

The momentum strategy is based on John Bollinger’s traditional method of using Bollinger Bands.

First, remember that Bollinger Bands define when price is high or low on a relative basis.

When the price is relatively high or low, it can be a signal of upward or downward momentum, respectively.

To execute this strategy, traders buy when the price is “relatively high” and the upper band is touched or broken then a bullish chart pattern such as a double bottom or W bottom precedes it.

If this strategy is successful then the price can “walk the upper band”or upwards.

Traders sell at resistance levels or if there are any bearish signals including negative price action, break of support etc.

On the other hand, traders sell when the price is “relatively low” and the lower band is touched or broken and it is preceded by a bearish chart pattern such as a double top or M top or the three pushes.

If this strategy is successful, the price can walk the lower band or downwards.

Traders cover at support levels or if there are any bullish signals including positive price action, resistance breaking etc.

As with any trading strategy, traders should look for entry points with the least amount of risk, the highest probability ideally 2:1 or more and odds of success in their favor.

It is important to set a stop-loss order if the price pulls back from the momentum direction.

Mean Reversion Strategy

The Bollinger Band Mean Reversion Strategy is based on the idea that prices revert to their mean, which is represented by the line between the Bollinger Bands.

When prices deviate too far from the mean, they are believed to eventually revert.

To execute the strategy, traders usually wait for the price outside the upper or lower Bollinger Bands.

When this happens, it is considered an overbought or oversold condition, respectively.

Traders then look back towards the centre line, which represents the average.

A common approach to trading means reversion using Bollinger Bands is to wait for price to retrace inside the Bollinger Bands before entering a trade.

This helps ensure that a reversal is actually happening and reduces the risk of entering a trade too early

Squeeze strategy

The Squeeze strategy is used by traders to identify potential breakout opportunities in a range-bound market in Bollinger Band.

Bollinger Bands indicate the volatility of the asset being traded, and the trend and contraction of Bollinger Bands indicate a decrease in volatility.

Traders use this signal to spot potential breakouts, as declining volatility is often followed by sharp increases in volatility.

To execute the strategy, traders look for a contraction in the Bollinger bands and wait for the price to break out of the bands.

They enter a long position if the price breaks above the upper Bollinger Band or a short position if the price breaks below the lower Bollinger Band.

To manage the risk, they set a stop-loss order opposite the breakout.

Double Bollinger Band Strategy

The Double Bollinger Bands strategy uses two sets of Bollinger Bands they are with 1 standard deviation and the other with 2 standard deviations.

The idea is that wide Bollinger bands (with 2 standard deviations) capture the main trend.

Movements, such as narrow Bollinger Bands (with 1 standard deviation) help filter out false signals and provide confirmation of trend changes.

In this strategy, when the price is between the upper two lines (buy zone), it is considered an uptrend and when the price is between the lower two lines (sell zone), it is considered a downtrend.

When the price is between the inner lines such that narrow Bollinger bands with 1 standard deviation it is considered as neutral.

To execute the strategy in an uptrend, traders look for buying opportunities when the price returns to the lower band of the buy zone.

In a downtrend, traders look for selling opportunities when the price rallies to the upper band of the sell zone.

When the market is neutral then the traders can look fora breakout or they wait for a trend to emerge.

It is important to use additional technical analysis tools to confirm entries.
