What Is Technical Analysis, and Where Does It Stop?
Technical analysis means reading the history of price and volume to understand how a stock has been moving and which scenarios are possible next. It is a useful way to describe a stock, not a crystal ball that knows tomorrow.
What you will learn
Know exactly what technical analysis looks at.
See why its output is scenarios and odds, never a certain forecast.

Every trade in a stock leaves a trace: a price, a quantity and a time. Technical analysis collects those traces on a picture called a chart and tries to answer simple questions. Is the stock moving up, down or sideways? Are there price levels it has returned to several times? Did the latest move come with heavy or light trading?
The thinking behind it is that price reflects the decisions of many people, and people behave in ways that repeat. They buy near a zone where the stock looked cheap before, and sell when it returns to a price where they were losing and want to get out even. That repetition is not a law, but it is enough to make a chart useful as a description.
It sees
1Price: open, close, high and low
2Volume: how many shares changed hands
3The order in time: trends, levels the price keeps returning to
It does not see
1News not yet out, or a sudden decision
2The business itself: profits, debt, value
3What the next buyers and sellers intend
Technical analysis sees price, volume and their order in time. It cannot see news that is not out yet.
The output is scenarios, not a forecast
The most important thing to grasp from day one: a chart does not tell you what the stock will do. It helps you lay out scenarios and know how each one would look on the chart if it happened.
ExampleAn invented company, Al Reef Fertilizers, trades at EGP 12.00. Over recent months it fell to the 11.50 area twice and bounced both times. Technical analysis does not say "the stock will rise" here. It says: as long as the price stays above 11.50, that zone still holds; if it closes clearly below, the reading changes. The gap between the current price and the zone is EGP 0.50, about 4.2%.
Price now12.00A zone it bounced from before: 11.50
Scenario APrice stays above 11.50Reading: the zone still holds
Scenario BCloses below 11.50Reading: the zone broke
The same chart gives two scenarios. It describes each one; it does not pick one.
Where technical analysis stops
It cannot see newsA disclosure or a sudden decision can wipe out any chart pattern in one session.
It does not measure valueA chart can look strong for a loss-making company, or weak for a sound one. That is the job of fundamental analysis.
Patterns failAny pattern or level can fail to work, and no rule succeeds every time.
Thin trading distorts the pictureIn a stock with few trades, one large trade can draw a shape that says little about the market.
Watch outIf someone tells you a chart "confirms" a stock will reach a given price, that claims more than the tool can say. Technical analysis describes odds, and odds are never certainty.
Look at a real chart
Open any stock chart and answer three questions. Is it moving up, down or sideways? Is there a zone it keeps returning to? Did the latest move come with heavy or light trading?
