Technical Analysis Explained: What Charts Can and Cannot Tell You

The daily chart shows five bars. The first two close higher on rising volume. The third gaps up and trades to a new high. Then it closes near its low. The fourth and fifth drift lower on quiet volume and stop just above last month’s high.

A technical analyst reads that sequence as a strong move, a failed push, and a pullback to a level where buyers were active before, and nothing in those five bars says what the company earns, whether its product is selling, or what the CEO will say next quarter. What the bars do give you is a place to act and a place to admit you were wrong. For a trader, that covers most of the job.

What can a chart actually tell you?

It shows trend first. Prices are making higher highs and higher lows, lower ones, or neither. It also shows where a trade is wrong: if you buy a pullback to support and price closes well below that support, the reason for the trade has failed, and the chart tells you the price at which that happens before you enter. And it helps with timing, because a stock that has been falling for three weeks and a stock that has just bounced off a rising average are different entries even if the business behind both is identical.

A chart cannot tell you what a business is worth. Nor can it know tomorrow’s news. A surprise guidance cut, a drug approval ruling or a merger announced before the open all arrive from outside the price record, and when the information traders were acting on changes overnight, the history on your screen stops describing the present.

What tools do technical analysts use?

Most tools belong to one of the groups below. Knowing the group tells you what question a tool answers. That keeps you from stacking indicators that all say the same thing.

Group	Tools	Question it answers
Trend	Moving averages (simple and exponential)	Which way is price going, and how steadily?
Momentum	RSI, MACD	Is the move speeding up or running out of push?
Volatility	ATR, Bollinger Bands	How far does this stock normally move in a day or a week?
Levels	Support, resistance, Fibonacci retracements	Where have buyers or sellers stepped in before?
Patterns	Cup and handle, flags, breakouts	Has price built a shape that often comes before a move?

Momentum tools are derived from price, so they lag it. Volatility tools size your stop. Levels and patterns are where most entries get planned, and the page on the best swing trading indicators goes through which of these tools earn a place on a swing chart and which ones mostly repeat what price already shows.

How is it different from fundamental analysis?

Fundamental analysis looks at the business. Revenue, margins, debt and cash flow all go into the price you are willing to pay for each dollar of earnings, so it asks what the company is worth. Technical analysis asks what the stock is doing.

Neither is complete alone. Many investors split the work between them, using fundamentals to choose what to own and the chart to choose the day, the size and the exit, and a long-term investor may never look at RSI while a swing trader holding for eight days may never open a 10-K.

A worked example: buying a pullback

Take a hypothetical stock that ran from $50 to $60 over three weeks. It trades above a rising 50-day moving average. Then it pulls back. To estimate where the pullback might reasonably stop, measure the 38.2% retracement of the $10 swing.

Suppose the pullback stalls there. It makes a low at $56.00. The next bar closes back up at $56.50, and that low becomes the most recent swing low. Buy at $56.50 with a stop at $55.50, below the swing low, and your risk is $1.00 a share, while a retest of $60 would pay $3.50, or 3.5 times what you put at risk on the trade. If price closes below $55.50, the setup is off.

The Fibonacci retracement definition covers the other levels. The 50-day average matters too. Below a falling 50-day, the same retracement is a bounce inside a downtrend, which is a weaker trade.

How do you start without drowning in indicators?

Keep it narrow for the first few months.

1. Pick one timeframe, such as the daily chart.
2. Choose three indicators from different groups, for example a 50-day moving average, RSI and ATR, and learn how each one is calculated before you let it decide anything.
3. Write your entry, stop and exit rules down.
4. Keep a trading journal with a screenshot of each chart at entry and at exit, the reason for the trade, the stop, the result in multiples of your risk, and a line on whether you followed your own rules, since a rule you break half the time has never really been tested.

Write the rules in sentences someone else could follow, including the condition that tells you to skip a trade. The swing trader’s vocabulary helps while the words are new, and the technical analysis topic page collects the definitions and strategies in one place.
