On Trends
Market movements can create a bewildering number of patterns and variations
of patterns. Simple structures take on different meanings depending on context,
and patterns sometimes develop and resolve in unexpected ways. Add to this the
complexities of the interactions of multiple time frames and related markets, and we end
up with a seemingly infinite number of possibilities. The human mind needs some kind of
structure to help process information, so various solutions have been proposed by different schools of technical analysis. The classic chart patterns (head and shoulders, double
top, pennant, flag, wedge, etc.) are one attempt at providing structure. Other solutions
have been proposed, ranging from in-depth quantitative analysis to the various schools
of wave and cycle analysis; these, and many other approaches, work for some traders.
All of these offer valuable perspectives, but let us turn our attention to a simple, robust
framework that focuses on the fundamental price structures created by price trends.
What I am presenting here is not new; I owe a tremendous debt to the authors and
traders who have come before me. No significant intellectual construct emerges ex
nihilo—anything of value rests on a foundation built by someone else.
In the case of
trend structure, Tony Plummer (2010) has written about the basic trend pattern, which
he calls the “price pulse,” with clarity and in-depth. This simple, fundamental trend pattern is found at the core of even elaborate methodologies, like Gann or Elliott, when
they are stripped to bare essentials. This pattern, very simply, is how markets move, and
it is a profoundly powerful concept. The fundamental pattern of market movement on
all time frames is this: a movement in one direction, a countertrend retracement in the
other direction, and another leg in the original direction. Visually, these movements are
often labeled with letters, as in Figure 3.1.
This is a very rough schematic structure, but it is a powerful pattern that repeats on
all time frames. Whether we look at trends spanning decades or seconds, we will find this
same impulse, retracement, impulse structure, though the psychological significance of
the pattern will vary depending on the time frame. It is also reasonable to ask why this
structure should exist at all, and there are several possible answers. Put yourself in the
shoes of a trader who has to buy a significant amount of an asset in a very short time.
Your primary objective is to get the order done without having a large impact on prices.
How might this best be done?
The best option in most cases is to buy a little bit, wait so that you don’t move the
market too much, then buy some more, and repeat until the order is completely filled.
This is how good execution traders work large orders. Smart traders (or smart algorithms) will judge how to plan their buying by the market’s response to their orders. In
this way, they are judging the supply or the selling conviction hanging over the market.
A single trader executing an order in a market otherwise composed of pure noise traders
would create some variation of this price pattern by trying to fill a buy order through this
natural process.
There must be a firm theoretical foundation for anything in the market; you should
be able to clearly articulate why something should be the way it is. Market prices are the
result of buyers and sellers negotiating for prices, nothing more and nothing less. We do
not need to invoke some mystical force to create the patterns we see in the markets; they
are simply the result of buyers and sellers finding prices in a competitive environment.
This is also why the fundamental structures in the markets have not changed since antiquity. Some of the earliest written records we have are price records from Phoenician
merchants, which paint a story of price movements very similar to those we see today,
albeit on a much slower scale.TREND STRUCTURE
We now turn to the structure of trends in a little more depth: how they start, how they
unfold, and how they come to an end. The presence of a trend suggests an imbalance of buying and selling pressure; it is this imbalance that actually drives the price change of
the trend, and the trend will eventually end when the market finds equilibrium at a new
price level. It is extremely important to be able to read the trend structure and to know
what patterns support a continued imbalance or what patterns indicate that the trend
might be coming to an end.
Using Indicators
This section will also use the indicators that I have found most useful in actual trading: modified Keltner channels set 2.25 multiples of the Average True Range (ATR)
around a 20-period exponential moving average, and a modified moving average convergence/divergence (MACD). These tools are examined in detail in Chapter 7 and Appendix
B, but the focus here will be on actually using them to delineate market structure in a
discretionary context. If you prefer a different set of indicators, you will find that these
same concepts can be adapted to a wide range of tools without loss of generality. For instance, most of the Keltner concepts can also apply to Bollinger bands or even to simple,
static percentage bands around a moving average. Most momentum indicators (e.g., rate
of change [ROC], Commodity Channel Index [CCI], standard MACD, or some applications
of the stochastic oscillator) can be used more or less like the modified MACD.
Impulse and Momentum
The first leg (AB) of the basic structure is often called a momentum move or an impulse
move. In an uptrend, this is a relatively sharp advance driven by buying pressure (demand) overcoming existing selling pressure (supply) and creating a lack of liquidity on
one side of the market. After a market has been locked in an extended trading range with
no clear momentum, the emergence of a sharp momentum move penetrating one side
of the range is often a sign that there is a new imbalance of buying or selling pressure.
Figure 3.3 shows an example of a new trend emerging in the 30-year Treasury bond futures. Notice a few things about this pattern: first, it is not subtle. Even someone with no
chart-reading experience would recognize that the right side of the chart shows a break
in the existing pattern. Next, notice that prices were able to penetrate through the upper
channel, though the last bar of the chart is somewhat suggestive of a short-term climax.
Last, the fast line of the MACD registered a new momentum high. (This idea will be explored in Chapter 7, but essentially, the MACD made a new high reading relative to its
recent values.)
Figure 3.4 shows an example of a downtrend emerging in the intraday Standard &
Poor’s (S&P) 500 futures. In this case, a large downward-closing 5-minute bar penetrates
the lower channel, and spikes the MACD to a significant new low. This brings up an
important idiosyncrasy of the MACD: the indicator is calculated from moving averages,
which smooth and lag prices, so the indicator also lags price movements. It is important
to understand this and to understand the picture you would have seen at the time. (Lay
a piece of paper over the chart to hide everything to the right of the price spike, and
then slide it to the right to reveal one bar at a time to see the response of the indicator.)
Also, notice that both of these cases are very clear, and that the indicator is somewhat
redundant because the information is already clearly visible in the price structure.
Impulse moves drive trends. As long as each trend leg extends in a momentum move
approximately consistent with previous moves, the probabilities favor buying the next
pullback for another trend high, or, in the case of a downtrend, shorting the pullbacks
for another run at the lows. What you do not want to see in a trend is the emergence of
sharp contratrend momentum on one of the pullbacks. Figure 3.5 shows an example in
which very sharp downward momentum emerged on a pullback in Sugar futures. Notice
that this pullback completely broke the established trend pattern, and spiked the MACD
to a sharp new low, which is not consistent with an intact uptrend. Though it is important
to understand the subtle clues the market gives us, sometimes the most important ones
are very obvious. There is no point trying to trade with the uptrend after an event like
this; it is safe to assume the trend is broken until further notice.
Remember, the normal pattern in an established trend is that each setup leg is a momentum move, and the subsequent extensions also function as momentum moves setting
up the next trend leg. Economics 101 tells us that increased demand in a market will lift
prices as the market tries to find a new market-clearing price; this description of trend
movement is one of the mechanisms through which that adjustment happens. Eventually,
higher prices will bring enough sellers into the market that a new, perhaps temporary,
equilibrium is achieved. Astute technical traders can usually see clues to this process
in the market tape. The most important patterns are: new momentum highs or lows,
subsequent trend legs making similar new impulse moves, and the absence of strong
countertrend momentum on pullbacks.
