Confirming Trend Weakness: Lagging Trends
Since volume most often precedes price,
weakening volume during a trend shows that traders lack the conviction
necessary to keep the trend moving. This lack of conviction eventually shows up
in reduced buying or selling pressure, which can spell doom for the
continuation of a trend. This type of divergence is especially noticeable in
uptrends. In an uptrend, as price climbs higher, more buying pressure is needed
to sustain the move. Consistent or increasing volume is the signature of a
robust trend. But if a security reaches a point at which those who planned to
buy have already purchased their shares, the volume begins to weaken (or lag),
and simple profit taking can cause the beginning of a serious correction.
Johnson & Johnson (JNJ) in Chart 4.11 is an example of a lagging
uptrend, as volume is weakening throughout the trend. Notice how the 50-day
moving average of volume is drifting lower as price rises. The declining volume
during the uptrend indicates that fewer buyers are participating as prices
appreciate. That situation leaves the door open for a nasty decline, as the
chart illustrates.
As evidenced in
Chart 4.12, a MACD overlay of volume can be a great short-term
momentum tool to show the strength of volume pushes at various stages of a
trend. Volume MACD can also be used to show lagging
Chart 4.11 Lagging Uptrend, VMA Overlay,
Johnson & Johnson
Chart 4.12 Lagging Uptrend, Volume MACD
Overlay, Johnson & Johnson
trends. Remember: When the MACD is
below the zero line, it is in a weak position, and, when it is above the zero
line, it is in a position of strength. In Chart
4.12 for Johnson & Johnson, note how the MACD of volume showed weakness
(below the zero line) as price pushed higher. Then, note how the volume MACD
spiked once sellers took over.
Trendless Markets: Volume Patterns at Support and Resistance
Levels
As we discussed previously, a trendless
or sideways market usually moves between upper and lower price boundaries.
These boundaries are known as support (the lower boundary) and resistance (the
upper boundary). Volume characteristics around areas of support and resistance
help to predict the future direction of the trend.
Volume
Accumulation at Support
Support can be thought of as the lower
boundary of what is perceived as good value for the security between buyers and
sellers. As price approaches the lower boundary support level, either buyers
accumulate shares or selling pressure diminishes. In either case, prices are
prevented from falling any further because of value that is perceived for the
time being at that price level. Support levels can be easily identified on a
chart by simply connecting the daily price lows during a particular time
period. The level at which buyers enter is usually more of a tight price range
near the support level than a specific price target.
Even though the dynamics of support
zones are such that good value is seen at that price, there is no guarantee
that the support level will hold. If it is broken, that is a sign that the
sellers have won the battle by bringing more supply than the market can bear,
causing price to adjust, sometimes sharply, to lower levels. As price
approaches the support area, volume behavior can give clues as to the actions
of the larger players, such as institutions and hedge funds. If volume
increases and the price support area holds, this demonstrates buying interest
at that level, which is usually a clue that the larger players are accumulating
shares or contracts.
Chart 4.13 for Barrick Gold (ABX) shows how volume increased
repeatedly as price approached the support area. The fact that volume increased
and price reversed higher off support showed that the buying pressure at
support was enough to create an imbalance on the side of demand over
Chart 4.13 Trendless
Market, Support Level Accumulation, Barrick Gold
supply, which then pushed prices
higher. Instead of continuing to purchase shares, however, buyers were content
to let the price drift back down to accumulate shares again at a price level
seen as a good value. After repeating this relatively bullish accumulation, the
trendless pattern was broken as volume increased sharply with a strong price
move to $48 after the period of accumulation in the $27—$28 range.
When
Accumulation at Support Fails
While Chart 4.13 for Barrick Gold shows how shares are being accumulated
as price bounces higher off of support on increased volume, there are other
times where there is no evidence of buying at the support level. These
situations can lead to breaks below support, or sharper price breakdowns.
Citigroup (C) in Chart 4.14 is an example of a price support around the $45 area.
Notice how, as price moves lower and approaches the support line, the action
(volume) is much more subdued than in the previous example. There are some
minor pops higher in Citigroup’s volume, but nothing that shows that a real
battle between buyers and sellers is taking place.
Chart 4.14 Trendless
Market, Lack of Accumulation at Support, Citigroup
Finally, notice how volume picks up in
mid-October as price falls, indicating a new supply of shares entering the
market. Since there was not enough demand to absorb this new supply, price
adjusted lower by breaking down through support.
Volume
Distribution at Resistance
Resistance is a price boundary where
supply levels prevent price from rising any further. The price at resistance is
seen as the upper boundary of what is perceived as good value by traders. The
most common method for determining the boundary range for resistance is to draw
a line through an equity's respective highs during the time frame under
analysis. A second method is to compare the amount of volume at a given price
point with the amount of volume that was traded the last time it reached that
same price point. If volume was greater on a previous attempt, then the
resistance may be inferred as holding. Conversely, if volume was less on a
previous attempt, then resistance may be failing, and a breakout could be
imminent. As price reaches a resistance level or zone, either sellers take
profits or buying pressure diminishes. Distribution at resistance is
accompanied by an increase in volume over the previous day without price
appreciation. If price is to get through a resistance area, a large enough
increase in volume is needed to absorb the overhead supply. If volume does not
increase to provide the fuel necessary to push through resistance, then either
price will remain in a trading range or sellers will take over and drive the price
lower.
IBM in Chart 4.15 gives a great example of a resistance area that needed
an increase in volume to push through. Notice how volume was weak throughout
the time that resistance held in the $77- $78 area. That signified that there
was not much conviction or passion among buyers or sellers. Once buyers decided
that the prospects for IBM made it worth more than $78 per share, they entered
the market and provided enough buying power (volume) to absorb the overhead
supply of shares, which in turn allowed IBM to move significantly higher.
The IBM example in Chart 4.15 was a happy ending for those buying IBM stock, but what
about the other side, or when sellers overwhelm buyers? Remember, a resistance
level is in place because there is more supply than demand at that price. If
there is not enough conviction among buyers to push the price higher, then
prices will ultimately move lower.
Chart 4.16 for KLA Tencor (KLAC) shows how the dynamics of price and
volume around a resistance area can give clues to whether or not that
resistance area is likely to hold. Notice how in October 2009 KLA
Chart 4.15 IBM Breakout over Resistance
Chart 4.16 Resistance in Trendless Market
with Downside Breakout Volume Support, KLA Tencor
Tencor made a price high on solid
volume in the 37.50 area. After a good sell-off, price once again approached
the 37.50 level in December, but this time volume was much lighter. If nothing
had materially changed for KLA Tencor over the previous couple of months,
chances were that 37.50 would still be viewed as the upper end of fair value
for the stock. If sellers were going to emerge at that level, the lighter
volume in December was a clue that there may not have been enough demand at
37.50 to push price through that level.
Sure enough, after churning sideways
for about three weeks in December at resistance, volume picked up as price
fell. There was already some evidence that there was not much demand interest
at this level, as demonstrated by the low volume. That opened the door for
selling pressure or a new supply of shares coming onto the market to drive
prices sharply lower. Notice how the increase in volume showed that change was
on the way in the form of increased selling activity. This is a good example of
how volume precedes price.
Volume in Action: Trend Consolidation/ Continuation Chart
Patterns
In this section we will take a look at
how volume behaves during a trend consolidation phase and breaks out in a
continuation of the previous trend. We explore the corresponding volume
patterns of some of the more widely recognized price chart patterns used in
trading today.
Volume Behavior in Pennants
A pennant is short term in nature
(usually lasting from 1 to 12 weeks) and normally reflects a brief
consolidation before the continuation of the previous trend. Since this pattern
represents short-term consolidation and trader indecision, it can on very rare
occasions be a reversal pattern (as will be shown
in Chapter 5), but the overwhelming majority of the time it represents
a short pause before the prevailing trend resumes. This pattern typically forms
at the midpoint of a move and occurs after a sharp price advance or decline,
depending on the trend direction, on heavy volume. A breakout of the pattern on
an increase in volume signals that the trend is resuming.
Chart 4.17 shows an example of a pennant pattern for Cisco Systems
(CSCO). The pennant pattern is formed by price fluctuations within a range, and
it needs at least two touches each on the resistance line and the support line
to be valid. The pennant formation is recognized by its
Chart 4.17 Bullish Pennant Pattern
Confirming Uptrend, Cisco Systems
Symmetrical triangle shape, with price
action being compressed as the pattern matures.
Note that the “flagpole”
is an important component of the pennant formation. It is the distance
from the break of either support or resistance, depending on trend direction,
to the high or low of the pennant. The flagpole must be formed on heavy volume
to validate the pattern. Once the pattern is validated, the length of the
flagpole is used to compute a price target for the move. Chart 4.17 shows a
bullish pennant formation, its characteristics, and how to compute a price
target:
- The price move starts at the $18 price
level in July 2009.
- Price rallies sharply, breaking through
resistance at $20.35 and hitting a high of $22.74 before the consolidation
begins.
- Once a valid pennant forms, with at
least two touches on each boundary line on contracting volume, a calculation of
the length of the flagpole can be done as follows in order to set a trading
price target:
- Measure from the point of the breakout
over resistance ($20.35) to the top of the initial rally ($22.74) and subtract
the breakout level from the high ($22.74 - 20.35 = $2.29). The computed value
($2.29) is used on the breakout of the pennant formation to project the price
target.
- Once price breaks out of the pennant
formation on heavy volume, add the length of the flagpole ($2.29) to the price
at the point it broke out of the pennant, in this case $22.35, to get the
trading price target of $24.64.
Volume
Behavior in Flags
Flags are also short term in nature,
lasting from 1 to 12 weeks. A flag is a small rectangular pattern that develops
against the prevailing trend. For example, if the trend is up, the flag forms
in a downward-sloping manner (a bull flag), and vice versa for downtrends (a
bear flag). As with pennants, the pattern develops between a support and a
resistance line. The flag differs from the pennant in that the flag is defined
and contained by two parallel lines, while the pennant features two converging
lines.
Volume is a key component in the
development of the flag pattern. The flag formation also needs a flagpole,
which must be formed on an increase in volume. Next, volume must contract as
the flag pattern forms and matures. Finally, volume must confirm a breakout of
the pattern by increasing noticeably at the point of the breakout. Chart 4.18
for iShares Barclays 20+ Year Treasury Bond Trust ETF (TLT) shows a bearish
flag formation, its characteristics, and how to compute a price target:
- The price decline starts in the $106
area in early April 2009.
- Price breaks down through support at
$100.38 on an increase in volume before finding support at $94.33, which is
where the price consolidation begins.
- Price then rises between two parallel
lines, forming a channel, or bearish flag, against the trend.
- Once the bearish flag formation is
realized, you can compute the length of the flagpole by subtracting the low
point of the flag ($94.33) from the support line that was broken ($100.38),
which gives a flagpole length of $6.05.
- Price breaks down out of the flag
formation at $96.70 on increasing volume, which validates the breakdown.
- The length of the flagpole ($6.05) is subtracted
from the breakdown point ($96.70) to project a price target of $90.65.

Using
Flags and Pennants in Practice
As with other patterns, suspected flag
and pennant formations can be misleading if you don't carefully follow a few
rules. Here are a few key points to remember about flag and pennant formations:
- The price action before the flag or
pennant forms must be a strong move with healthy volume. This action forms the
flagpole.
- The pennant forms a symmetrical
triangle pattern, while the flag forms against the trend in a channel between
two parallel lines. Volume contracts as the patterns are formed.
- The pattern becomes valid when there
are at least two touches on the upper and the lower boundary lines.
- A breakout of the pattern is validated
or confirmed by an increase in volume.
- The length of the flagpole is projected
from a break of either support or resistance to either the high or low point of
the formation, depending on the direction of the trend.
- The length of the flagpole is projected
from the breakout point of the pattern to generate a price target.
Volume
Behavior in Triangles
Triangles are patterns created during
consolidation phases, representing a pause in the prevailing trend before
continuing in the trend direction. They form in a horizontal consolidation that
reflects diminishing interest in trading a particular security. In order for
any triangle pattern to qualify as a continuation pattern, there must be a
pre-existing trend in place. A triangle is formed with at least two touches on
each of the converging support and resistance lines.
As with the previous
consolidation/continuation patterns, volume is lackluster while the triangle
forms. An increase in volume is used to confirm, or validate, the breakout of
the pattern. Triangles come in three forms:
- Ascending
- Descending
- Symmetrical
Ascending
Triangles
An ascending triangle is a bullish
pattern that has a flat top line (representing resistance) and an
upward-sloping bottom line (representing support). The pattern consists of at
least two highs at or near the same price level, with higher lows made on each
rally attempt. The higher lows on each decline show diminishing supply or
selling pressure on each push lower, which causes the upward-sloping support
line. Volume should be lower than average and/or be decreasing as the pattern
develops and the price action is compressed.
Chart 4.19 for Euro FX Composite illustrates the ascending triangle.
Notice the flat resistance line and the upward-sloping support line. The
resistance level was set at $1.2359 on the January 2006 high. Price declined
after that, and the consolidation process started as price made a series of
higher lows with each decline. Price then made another attempt to break through
resistance at $1.2359, but was temporarily turned away, resulting in one final
touch of the support line. The next attempt to break out was successful, as
volume increased, showing an increase in demand, which caused price to reset to
a new, higher level as the trend resumed.
Descending
Triangles
A descending triangle is a bearish
pattern because it appears primarily in downtrending markets. In contrast to
the ascending triangle, it consists of a flat lower line (support) and a
downward-sloping top line (resistance).
Chart 4.19 Bullish Ascending Triangle
Pattern, Euro FX Composite
The pattern consists of at least two
lows at or near the same price level, with lower highs made on each rally
attempt. The lower highs on each rally attempt indicate diminishing demand on
each push higher, thus causing the downward-sloping resistance line. Volume
should he lower than average and/or be decreasing as the pattern develops and
the price action is compressed.
Chart 4.20 for AMR Corp. shows a descending triangle. The initial low
of the pattern was made at $10 in March 2004, with a test of that low coming
later that year in May. That formed the flat support line in the $10 area,
which was the level to watch for a break lower. Notice how, as the pattern
formed, price made a lower high on each rally attempt, which allowed a
downward-sloping resistance line to be drawn by connecting the highs. Volume
was rather lackluster as the pattern developed before price finally broke lower
with increased volume in July as the downtrend resumed.
Symmetrical
Triangles
A symmetrical triangle is very similar
to a pennant formation because it involves the same basic shape. Symmetrical
triangles, however, are longer in duration, since they represent a longer-term
period of trader
Chart 4.20 Bearish Descending Triangle,
AMR Corp.
indecision. The consolidation period
shows an absence of conviction from both buyers and sellers, thus allowing
supply and demand to appear virtually equal as price consolidates sideways.
Volume should be lower than average and/or be decreasing as the pattern
develops and price action is compressed.
Chart 4.21 for Google (GOOG) shows a symmetrical triangle pattern that
formed following a sharp rally. The pattern lasted for eight months, however,
as lack of demand was matched by a lack of supply. Notice the pattern of lower
highs and higher lows as the support and resistance lines converge. Volume
moved higher as demand for Google shares finally forced the price higher to
break out of the triangle. The breakout was upward in continuation of the
previous trend, and the increased volume validated the breakout direction.
Volume Confirmation of Trend Continuation Patterns
These patterns can appear both in
trending markets and following consolidation patterns. They reflect the
resumption or continuation of a trend in its most recent direction.

Symmetrical Triangle Pattern, Google Inc.
Continuation
Gaps
Gaps are just what the name implies —a
large step up or down in price, forming a “gap” from
the previous position on tine chart. Most commonly, the term is used in the
context of a “gap open,” where the price opens substantially above or below
the previous closing price.
A continuation gap occurs in the middle
of a move and in the same direction as the existing trend. Unlike exhaustion
gaps, continuation gaps make good trade entry points in the existing trend, as
these patterns are a signal that buying or selling interest has accelerated.
These gaps are also known as measuring gaps or runaway gaps.
Chart 4.22 for Amazon.com (AMZN) shows a continuation gap in an
uptrend. Notice how price moved higher off the November 2008 low before forming
a bullish flag pattern as price consolidated. On January 30, 2009, price gapped
higher on huge volume, signaling that the newly formed uptrend was ready to
continue.
Candlestick
Continuation Patterns
Candlestick charts have become one of
the more popular tools of both the trader and the serious technician. The
candlestick charting method was developed in Japan in the seventeenth century.
Greg L. Morris introduced the software methodology to traders in the United
States back in the
Chart 4.22 Bullish Continuation Gap,
Amazon.com
early 1990s. As the story unfolds, a
Japanese rice futures trader noticed that in addition to supply and demand,
trader emotion played a large part in market behavior. This emotion could
sometimes cause a disconnect between the price and the actual value of the rice
market. The candlestick methodology was developed in an attempt to graphically
represent intraday price relationships that were driven by trader sentiment.
Candlestick charting is very popular among active traders because it reflects
short-term outlooks (usually less than two weeks in duration). Chart 4.23 shows the components of a
candlestick.
The difference between standard bar
charting and candlestick charting is that the “real
body” of the candlestick shows the relationship between the open and
close for the period. If the close is higher than the open, the real body is
hollow or white. If the close is below the open, the real body is darkened,
whether it is black, red, or whatever color the chartist chooses. That is a
very simplistic overview of how candlesticks are constructed. Candlestick
charting is a very complex topic and beyond the scope of this book.
Chart 4.23 Components of a Candlestick
One example of a common candlestick
continuation pattern that is especially common in the foreign exchange (FX)
market is interestingly named the in-neck thrusting pattern. The example of the
E-Mini Euro FX futures contract in Chart
4.24 shows the in-neck thrusting pattern as it unfolds during a downward
move. Note that most candlestick patterns are short term in nature, so they
develop quickly. Chart 4.24
illustrates the pattern in a downtrend, but this pattern is also valid in
uptrends as well. In the downtrend example in Chart 4.24, the pattern unfolds as follows:
Day 1. Consists of a long black candle
signaling the conviction among sellers
Day 2. The candle has a white body
(which means that the closing price is above the opening price) as buyers step
in to try to stem the decline. This candle usually has a long tail, which signals
that there was a strong battle to push price lower, but for this day the buyers
prevailed.
Day 3. On the third day, buyers attempt
to push price higher but fail, and the sellers resume control, which results in
another large black candle resuming the downtrend.

Pattern, E-Mini Euro Futures
Volume increases throughout the
pattern, showing a definite battle for control of the market. In this case, it
was ultimately won by sellers.
This chapter has presented volume
overlays as a way to detect and assess trend strength. We have also learned to identify
and confirm price chart formations using their corresponding volume patterns to
predict continuation in trend direction.
Summary
- Volume allows traders the opportunity
to see how much intensity or conviction is behind price movements of individual
stocks or the market as a whole. In a sense, volume “validates” price movements
and can also give insight as to whether a trend is likely to continue or change
direction. Keep in mind the trader s mantra: Volume precedes price.
- As such, volume will show changes in
its characteristics that will alert traders to the end of an uptrend or a
downtrend before the price actually reverses. For example, in a downtrending
market, the volume should expand during the down moves (confirmation of trend)
and contract during countertrend bounces. When the volume patterns begin to
change, they serve to alert a trader to shifts in trend.
- Trends, and the strength of those
trends, can be assessed and confirmed through the use of overlays to determine
volume strength and the conviction behind price movement. Such overlays can
confirm robust or lagging trends.
- Popular overlays include volume moving
averages, linear regression, and Moving Average Convergence/Divergence (MACD)
of volume.
- Price formation patterns, when used in
conjunction with their corresponding volume patterns, can also give strong
confirmation as to the direction of a tradeworthy trend. Spotting the price
patterns and corresponding volume patterns of pennants, flags, triangles, and
gaps helps to predict a continuation in trend direction.
