The great following which Bollinger bands have achieved is largely due to their flexibility. They can be used for many different ends and by traders of all levels. One use in particular which has proved very popular is using the bands to accurately predict the timing of price breakouts.
The analysis and prediction of price breakouts which Bollinger bands provide are invaluable in terms of guiding a trader’s decision. They inform a trader whether it is advisable to act according to whether the direction of the breakout in known or not.
Bollinger bands also serve to re-affirm in traders’ minds that securities, more often than not, trade within a range. Bollinger bands serve to prove this as prices can be seen to be contained within the upper and lower bands.
However, prices do not always harmoniously stay between these two bands. Often there will be price breakouts – where the price breaks through one of the bands. In this instance the trader must know how to act appropriately depending on what direction they feel the breakout will go. Bollinger bands help greatly with this prediction.
In order to be able to use Bollinger bands effectively in terms of judging a price breakout, numerous factors must be in place first. For starters, the distance between the upper and lower bands must be small, meaning low market volatility. This coupled with the bands lying in a horizontal direction usually means a price break is on the way.
The trader is then left with two options if a break out occurs. They can take positive action and play the market or leave the market.
When we refer to playing the market, we mean that a trader can place a pending buy and sell on each side of the price meaning that a position in the market is guaranteed. Another way in which a trader can attempt to predict the direction that the break out will take is through the use of other methods in conjunction with Bollinger bands. This method is usually seen as more reliable as more variables are taken into account.
Bollinger Bands Once these two bands are very constricted they should ideally both be heading in a horizontal direction. A trader can take advantage of this situation by placing pending buys or sells at the resistance and support lines. If a particular security has high volatility its potential price can occur anyway over a large range of values.
