Which way is the market moving?
How far up or down will it go? And when will it go the other
way? These are the basic concerns of the technical analyst.
Behind the charts and graphs and mathematical formulas used
to analyze market trends are some basic concepts that apply
to most of the theories employed by today's technical
analysts.
John Murphy, a leader in technical analysis of futures
markets, has drawn upon his thirty years of experience in
the field to develop ten basic laws of technical trading:
rules that are designed to help explain the whole idea of
technical trading for the beginner and to streamline the
trading methodology for the more experienced practitioner.
These precepts define the key tools of technical analysis
and how to use them to identify buying and selling
opportunities.
Mr. Murphy was the technical analyst for CNBC-TV for
seven years on the popular show "Tech Talk" and has authored
three best-selling books on the subject -- Technical
Analysis of the Financial Markets, Intermarket Technical
Analysis and The Visual Investor.
His most recent book demonstrates the essential "visual"
elements of technical analysis. The fundamentals of Mr.
Murphy's approach to technical analysis illustrate that it
is more important to determine where a market is going (up
or down) rather than the why behind it.
The following are Mr. Murphy's ten most important rules
of technical trading:

1. Map the Trends:
Study long-term charts. Begin a chart analysis with
monthly and weekly charts spanning several years. A larger
scale "map of the market" provides more visibility and a
better long-term perspective on a market. Once the long-term
has been established, then consult daily and intra-day
charts. A short-term market view alone can often be
deceptive. Even if you only trade the very short term, you
will do better if you're trading in the same direction as
the intermediate and longer term trends.
2. Spot the Trend and Go With It:
Determine the trend and follow it. Market trends come in
many sizes -- long-term, intermediate-term and short-term.
First, determine which one you're going to trade and use the
appropriate chart. Make sure you trade in the direction of
that trend. Buy dips if the trend is up. Sell rallies if the
trend is down. If you're trading the intermediate trend, use
daily and weekly charts. If you're day trading, use daily
and intra-day charts. But in each case, let the longer range
chart determine the trend, and then use the shorter term
chart for timing.
3. Find the Low and High of It:
Find support and resistance levels. The best place to buy
a market is near support levels. That support is usually a
previous reaction low. The best place to sell a market is
near resistance levels. Resistance is usually a previous
peak. After a resistance peak has been broken, it will
usually provide support on subsequent pullbacks. In other
words, the old "high" becomes the new "low." In the same
way, when a support level has been broken, it will usually
produce selling on subsequent rallies -- the old "low" can
become the new "high."
4. Know How Far to Backtrack:
Measure percentage retracements. Market corrections up or
down usually retrace a significant portion of the previous
trend. You can measure the corrections in an existing trend
in simple percentages. A fifty percent retracement of a
prior trend is most common. A minimum retracement is usually
one-third of the prior trend. The maximum retracement is
usually two-thirds. Fibonacci retracements of 38% and 62%
are also worth watching. During a pullback in an uptrend,
therefore, initial buy points are in the 33-38% retracement
area.
5. Draw the Line:
Draw trend lines. Trend lines are one of the simplest and
most effective charting tools. All you need is a straight
edge and two points on the chart. Up trend lines are drawn
along two successive lows. Down trend lines are drawn along
two successive peaks. Prices will often pull back to trend
lines before resuming their trend. The breaking of trend
lines usually signals a change in trend. A valid trend line
should be touched at least three times. The longer a trend
line has been in effect, and the more times it has been
tested, the more important it becomes.
6. Follow that Average:
Follow moving averages. Moving averages provide objective
buy and sell signals. They tell you if existing trend is
still in motion and help confirm a trend change. Moving
averages do not tell you in advance, however, that a trend
change is imminent. A combination chart of two moving
averages is the most popular way of finding trading signals.
Some popular futures combinations are 4- and 9-day moving
averages, 9- and 18-day, 5- and 20-day. Signals are given
when the shorter average line crosses the longer. Price
crossings above and below a 40-day moving average also
provide good trading signals. Since moving average chart
lines are trend-following indicators, they work best in a
trending market.
7. Learn the Turns:
Track oscillators. Oscillators help identify overbought
and oversold markets. While moving averages offer
confirmation of a market trend change, oscillators often
help warn us in advance that a market has rallied or fallen
too far and will soon turn. Two of the most popular are the
Relative Strength Index (RSI) and Stochastics. They both
work on a scale of 0 to 100. With the RSI, readings over 70
are overbought while readings below 30 are oversold. The
overbought and oversold values for Stochastics are 80 and
20. Most traders use 14-days or weeks for stochastics and
either 9 or 14 days or weeks for RSI. Oscillator divergences
often warn of market turns. These tools work best in a
trading market range. Weekly signals can be used as filters
on daily signals. Daily signals can be used as filters for
intra-day charts.
8. Know the Warning Signs:
Trade MACD. The Moving Average Convergence Divergence (MACD)
indicator (developed by Gerald Appel) combines a moving
average crossover system with the overbought/oversold
elements of an oscillator. A buy signal occurs when the
faster line crosses above the slower and both lines are
below zero. A sell signal takes place when the faster line
crosses below the slower from above the zero line. Weekly
signals take precedence over daily signals. An MACD
histogram plots the difference between the two lines and
gives even earlier warnings of trend changes. It's called a
"histogram" because vertical bars are used to show the
difference between the two lines on the chart.
9. Trend or Not a Trend:
Use ADX. The Average Directional Movement Index (ADX)
line helps determine whether a market is in a trending or a
trading phase. It measures the degree of trend or direction
in the market. A rising ADX line suggests the presence of a
strong trend. A falling ADX line suggests the presence of a
trading market and the absence of a trend. A rising ADX line
favors moving averages; a falling ADX favors oscillators. By
plotting the direction of the ADX line, the trader is able
to determine which trading style and which set of indicators
are most suitable for the current market environment.
10. Know the Confirming Signs:
Include volume and open interest. Volume and open
interest are important confirming indicators in futures
markets. Volume precedes price. It's important to ensure
that heavier volume is taking place in the direction of the
prevailing trend. In an uptrend, heavier volume should be
seen on up days. Rising open interest confirms that new
money is supporting the prevailing trend. Declining open
interest is often a warning that the trend is near
completion. A solid price uptrend should be accompanied by
rising volume and rising open interest.
11. Technical analysis is a skill that improves with
experience and study. Always be a student and keep learning.

Leonardo Fibonacci was a thirteenth century mathematician
who "rediscovered" a precise and almost constant
relationship between Hindu-Arabic numbers in a sequence (1,
2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc. to infinity). The
sum of any two consecutive numbers in this sequence equals
the next higher number. After the first four, the ratio of
any number in the sequence to its next higher number
approaches .618. That ratio was known to the ancient Greek
and Egyptian mathematicians as the "Golden Mean" which had
critical applications in art, architecture and in nature.
Stochastics - an oscillator popularized by George Lane in
an article on the subject which appeared in 1984. It is
based on the observation that as prices increase, closing
prices tend to be closer to the upper end of the price
range; conversely, in down trends, closing prices tend to be
near the lower end of the range. Stochastics has slightly
wider overbought and oversold boundaries than the RSI and is
therefore a more volatile indicator. The term "stochastic"
refers to the location of a current futures price in
relation to its range over a set period of time (usually 14
days).
