Reversal Patterns (Tops
And Bottoms)
Reversal
patterns, or tops and bottoms, signify a fundamental
change in the long term trend.
Overview
- Tops are usually
less stable and shorter than bottoms.
- Bottoms usually
have smaller price variations and are slower
to establish.
- Volume is usually
more important on the upside.
- Confirmation
of a top or bottom is in a double top or
bottom (or a short channel.)
The most
popular Reversal Patterns include: head and
shoulders, double tops and bottoms, triple tops
and bottoms, and V-formations.
Interpretation & Signals
Head & Shoulders

The well
known head and shoulders pattern is formed by
three peaks; the center peak, or head, is slightly
higher than two lower, and not necessarily symmetrical,
shoulders. The line joining the bottoms of the
two shoulders is called the neckline. Due to
fluctuations, the neckline is rarely symmetrical
or perfectly horizontal.
The pattern
isn't complete until the neckline is broken.
It is often good to wait for confirmation -
for example, two successive closes below the
neckline. Remember, markets often bounce back
to the Neckline after the breakout and this
becomes a new level of resistance.
Volume
should be assessed to confirm the validity of
these patterns. Volume is normally heaviest
during the formation of the left shoulder and
also tends to be quite heavy as prices approach
the peak. The real confirmation of a developing
Head and Shoulders pattern comes with the formation
of the right shoulder, which is invariably accompanied
by distinctly lower volume.
Some traders
use the distance between the neckline and the
top of the head to project a "price
objective." The price objective
is determined by measuring from is the top of
the head to the neckline, and using this distance
from the breakout point downwards.
An Inverted
Head and Shoulders pattern is
a mirror image of the Head & Shoulders pattern
(forming a market bottom).
Double
Tops

Double
Tops are another reliable and frequently
used reversal pattern. This pattern consists
of two tops of approximately equal height. A
line is drawn below and parallel to the resistance
line that connects the two tops. The neckline
is a strong support for price level but eventually
fails.
As with
a Head and Shoulders, after the two rallies
and their respective reversals are completed
the double tops is confirmed only when the neckline
is broken. The support line then becomes a resistance
line, which often holds a market rebound.
A Double
Bottom pattern is a mirror image of a double
top pattern: The average height of the bottoms
gives a good indication of the price objective.
Triple
Top
A tnple
top is a cross between a head and shoulders
and double top. This formation consists of three
tops of approximately equal height. A line
is drawn below and parallel to the resistance
line that connects the three tops. The neckline
is a strong support for price level but eventually
fails. The support line then becomes a resistance
line, which usually holds any market rebound.
Triple
Bottom
A triple
bottom pattern is a cross
between an inverted head and shoulders and double
bottom pattern.
V-
Pattern
The V
pattern is an unusual pattern in that a sharp
trend switches from one direction to the other
without warning and with high volume at or just
after the turn around.
Further
points
Trend
reversals offer some of the most important opportunities
for entering a market with a good profit potential.
They usually represent fundamental changes in
the underlying character of a particular market
and often go on to yield big moves.
However,
a market top or bottom is often difficult
to identify. It is even more difficult to
choose appropriate entry and exit points. One
problem is distinguishing between an actual
change in trend or merely a congestive phase
in the middle of a move. It is usually advisable
to wait for prices to actually confirm a trend
reversal by developing one of these well-tested
and reliable reversal patterns. The actual buy
or sell signals are based on a breakout in the
direction of the new trend.
Here are
some general observations about Reversal patterns:
- A breakout
through a trend line is used in conjunction
with a price pattern to yield signals in
terms of both price level and timing.
- The longer
the time required to form a pattern and
the greater the price fluctuations
within it, the more substantial the
coming price movement is likely to be. The
time frame is normally from several days
to several months - intraday patterns are
not considered reliable.
