Bollinger Bands is
a chart indicator which is developed by a person named John Bollinger.
Hence the name
Bollinger bands.
It is a indicator
that is used to calculate the volatility of the market.
In other words,
this indicator has the ability to tell traders if the market is quiet or loud.
When the market is
loud, the Bollinger band expands and vice versa.
As price moves,
you will see the band expand as shown in the image below.
The most important
thing for a trader to know about an indicator is what the indicator does.
Of course, there
are complicated calculations and formulas behind the working operation of the
Bollinger Band but ultimately, you just need to know what it does.
The whole idea
behind the Bollinger band is that price will move within the band and most of
the time, the price will tend to return to the middle of the bands.
So, you can
actually tell where the price would be moving next right?
Based on the image
above, the price touch the top of the band.
In the image
below, the price bounces back and heads towards the middle of the band.
If you were to
enter a trade at the top of the band, you would have gotten some profit from
your trade.
The Bollinger
Bands can be regarded as a dynamic support and resistance level.
The bands tend to
be stronger with the higher time frames because there is less noise in the
market.
Most traders like
to use this indicator in a ranging market when there is no clear uptrend or
downtrends.
Nevertheless, Bollinger
bands can also be used by traders when there is a trend in the market.
Here is how it
works.
The bands will
squeeze together like in the image below and a breakout is waiting to occur.
If the candles
start to break out of the top of the band, the price will tend to pull away
going up.
If it breaks out
the band below, the price will continue to drop.
Basically, that is
how forex traders are able to use the Bollinger bands in their trading strategy.
So go ahead and test it out with the trading strategy that you have.
It might be of help.
If you already have a sound strategy in place, just treat this as extra knowledge.
