points, estimate which direction the stock will 
move, when a change in direction might take 
place and where a possible move might find 
support or resistance.
Charts also help to identify repetitive patterns of movement which can act as high probability 
indicators. Moreover, charts can graphically display when certain key events took place and what 
impact they had on the price of the stock (this is a point where fundamental and technical analysis 
may coincide). 
Moving Averages 
Don’t freak out when we start doing some math. There are fantastic computer programs and online 
stock screens that do all the number crunching for you but it is important to under-stand the 
principles involved in producing the charts that are the basic tools of the trade.
A chart of a Moving Average is another way to picture what shorter term cycles are doing within a 
larger cycle. As in channel analysis, after we note the overall trend of the price movement we try to 
locate supporting trends which work within the long trend.
What is a moving average? Moving averages are used to smooth out short-term fluctuations, which 
make it easier to identify trends or cycles. There are several variations of the moving average 
concept so we will begin with the simple moving average.
Simple moving average (SMA)
The following examples are from StockCharts.com a provider of professionally produced charting 
and technical analysis tools. 
How to Design and Construct An Effective Trading Plan

A simple moving average is formed by computing the average (mean) price of a security over a 
specified number of periods. While it is possible to create moving averages from the Open, the 
High, and the Low data points, most moving averages are created using the closing price. For 
example: a 5-day simple moving average is calculated by adding the closing prices for the last 5 
days and dividing the total by 5. 
The calculation is repeated for each price bar on the chart. The averages are then joined to form a 
smooth curving line - the moving average line. Continuing our example, if the next closing price in 
the average is 15, then this new period would be added and the oldest day, which is 10, would be 
dropped. The new 5-day simple moving average would be calculated as follows: 
Over the last 2 days, the SMA moved from 12 to 13. As new days are 
added, the old days will be subtracted and the moving average will 
continue to move over time. 
In this example, using closing prices from Eastman Kodak (EK), day 
10 is the first day possible to calculate a 10-day simple moving 
average. As the calculation continues, the newest day is added and the 
oldest day is subtracted. The 10-day SMA for day 11 is calculated by 
adding the prices of day 2 through day 11 and dividing by 10. The 
averaging process then moves on to the next day where the 10-day 
SMA for day 12 is calculated by adding the prices of day 3 through 
day 12 and dividing by 10. 
The following chart for Eastman Kodak displays the data in the left column.

This simple illustration highlights the fact that all moving averages are lagging indicators and 
will always be “behind” the price. The 
price of EK is trending down, but the 
simple moving average, which is based 
on the previous 10 days of data, remains 
above the price. If the price were rising, 
the SMA would most likely be below. 
Because moving averages are lagging 
indicators, they fit in the category of
