Basics of Charting
and Technical Analysis
Price Chart
A price chart is a sequence
of prices plotted over a specific timeframe. In statistical terms,
charts are referred to as time series plots. On the chart, the y-axis
(vertical axis) represents the price scale and the x-axis (horizontal
axis) represents the time scale. Prices are plotted from left to
right across the x-axis with the most recent plot being the furthest
right.
Technical Analysis
Technicians, technical
analysts and chartists use charts to analyze a wide array of securities
and forecast future price movements. The word "securities"
refers to any tradable financial instrument or quantifiable index
such as stocks, bonds, commodities, futures or market indices. Any
instrument with price data over a period of time can be used to
form a chart for analysis.
While technical analysts
use charts almost exclusively, the use of charts is not limited
to just technical analysis. Charts provide an easy-to-read graphical
representation of a instrument's price movement over a specific
period of time.
Time Intervals
A graphical historical
record makes it easy to spot the effect of key events on a instrument's
price, its performance over a period of time and whether it's trading
near its highs, near its lows, or in between. The timeframe used
for forming a chart depends on the compression of the data: intraday,
daily, weekly, monthly, quarterly or annual data. The less compressed
the data is, the more detail is displayed.
Intraday data is made
up of prices at which the trading takes place throughout the day,
it is also called tick-data if the prices are for individual trades,
rather than compressed in a minutely open-high-low-close format.
Daily data is made up of intraday data that has been compressed
to show each day as a single data point, or period. Weekly data
is made up of daily data that has been compressed to show each week
as a single data point. The more the data is compressed, the longer
the timeframe possible for displaying the data. The choice of data
compression and timeframe depends on the data available and your
trading or investing style.
Charts For Daytrading
Daytraders usually concentrate
on charts made up of intraday data to forecast short-term price
movements. The shorter the time frame and the less compressed the
data is, the more detail that is available. While long on detail,
short-term charts can be volatile. Large sudden price movements,
wide high-low ranges and price gaps can affect volatility.
Daytraders might use
a combination of long-term and short-term charts. Long-term charts
are good for analyzing the large picture to get a broad perspective
of the historical price action. Once the general picture is analyzed,
an intraday chart can be used to zoom in.
Chart Patterns
The hills and valleys,
shapes and curves that develop over time on a chart are found to
have predictive value for future market direction. Patterns can
either indicate a reversal or a continuation of an existing trend.
The pattern recognition
can be open to interpretation, which can be subject to personal
biases. To defend against biases and confirm pattern interpretations,
other aspects of technical analysis should be employed to verify
or refute the conclusions drawn. While many patterns may seem similar
in nature, no two patterns are exactly alike. False breakouts, bogus
reads and exceptions to the rule are all part of the ongoing education.
Reversal patterns
Often take a longer time
to form on the chart and represent changes in trend. The larger
the pattern, the greater the potential price movement. The height
of the pattern measures volatility, while the width measures time
required to complete the pattern. (Patterns at market tops are usually
more volatile and shorter in time than bottoms.) Remember, a trend
must exist for the pattern to be valid, and breaking a major trend
line does not necessarily indicate a trend reversal (it might be
the beginning of a sideways trend).
Continuation
patterns
It suggests that a market
is only pausing for a while before the prevailing trend will resume.
Continuation patterns are usually shorter-term in duration than
reversal patterns and are often classified as intermediate-term
chart patterns. Their signals often coincide with momentum and trend
indicators. These patterns have the same predictive value within
a chart of any time frame.
Let see some of the more
common reversal patterns include head-and-shoulders, double tops
and double bottoms and saucers. Some of the most common continuation
patterns include: flags, ascending and descending triangles, pennants,
gaps, and rectangles.
Summary
The keys to successful
chart analysis are dedication, focus and consistency.
· Dedication:
Learn the basics of chart analysis, apply your knowledge on a regular
basis and continue your development.
· Focus: Limit the number of charts, indicators
and methods you use. Learn how to use these and learn how to use
them well.
· Consistency: Study your charts on a regular
basis and study them often (daily if possible).
