Bollinger suggests looking for signs of non-confirmation when a security is making new highs. First, a security creates bollinger bands a reaction high above the upper band. Third, prices move above the prior high but fail to reach the upper band.
In particular, Bollinger looks for W-Bottoms where the second low is lower than the first but holds above the lower band. There are four steps to confirm a W-Bottom with Bollinger Bands. The ability to hold above the lower band on the test shows less weakness on the last decline. Fourth, the pattern is confirmed with a strong move off the second low and a resistance break.
Advanced use of Bollinger Bands
John Bollinger developed Bollinger Bands in the early 1980s and since their introduction 30 years ago they have become one of the most widely used technical indicators worldwide. Schwab does not recommend the use of technical analysis as a sole means of investment research. Next, multiply that standard deviation value by two and both add and subtract that amount from each point along the SMA. Almost all trading systems use Bollinger Bands in conjunction with the readings of other indicators.
- For example, IBM closed below the lower Bollinger Band® on February 26, 2007.
- As part of Bollinger trading, we are interested in technical filters.
- Between 1984 and 1991, John worked on his own trading system based on the LeDoux strategy and the envelope indicator.
- For example, long-term position traders may prefer to use a more significant number of periods and a higher standard deviation.
- In the process of their formation, there is a reversal of the price movement, which opens up opportunities for effective entry into the market.
- Likewise, “relatively low” should not be considered bullish or a buy signal.
Therefore, a protection needs to be in place once the decision to buy has been made. In the NYX example, the stock climbed undaunted after it closed below the lower Bollinger Band® a second time. Using the bands as overbought/oversold indicators relies on the concept of mean reversion of the price. Mean reversion assumes that, if the price deviates substantially from the mean or average, it eventually reverts back to the mean price. If you’re looking to go long when trading a squeeze, consider placing a buy entry point above the upper band. Once it’s executed, you could place an initial stop under the low of the breakout formation or under the lower band.
Using Bollinger Bands to Gauge Trends
When the price of the asset breaks below the lower band of the https://www.bigshotrading.info/®, prices have perhaps fallen too much and are due to bounce. On the other hand, when price breaks above the upper band, the market is perhaps overbought and due for a pullback. Bollinger Bands can also indicate the end of a strong trend. Strong trends, especially those developing after a breakout of a trading range, will result in an expansion in volatility that will cause the bands to initially move apart. This means that in a strong uptrend, the lower band will actually move downward in the opposite direction of the new trend. When the lower band turns back up, it can be a signal that the move higher might be over, at least for a while.

Bollinger Bands in Cryptocurrency Trading
Visually, these two technical indicators coincide at the moving average line but have different widths. A narrower channel is built with a factor of 1.0, and a wider one – with a factor of 2.0. When the price breaks out of this area, it is outside the root-mean-square distribution – it becomes an anomaly in terms of mathematical statistics. The second low must not be lower than the first one, and the second low mustn’t touch or spike the lower band. This bullish trading setup is confirmed when the price action moves and closes above the middle line (SMA). A breakout to the upside signals traders to initiate long positions or exit short positions.
