What is technical analysis?

Its three premises

1. Price reflects the available information. News, expectations, and emotions all end up expressed in what people are willing to pay.
2. Price moves in trends. The assumption is that once a move gets going, it tends to continue until something changes it.
3. Behavior repeats. People react in similar ways to fear and greed, and that leaves similar footprints on the charts.

None of the three is an exact law; they are working assumptions. Technical analysis doesn’t promise to predict the future. It offers a framework for making decisions with rules and with risk defined in advance.

The basic tools

• Candlestick charts: show the open, high, low, and close of each period.
• Trend: the direction of price based on its sequence of highs and lows.
• Support and resistance: zones where price has turned before.
• Chart patterns: formations such as the head and shoulders or the double top.
• Indicators: calculations based on price and volume, such as moving averages, the RSI, or the MACD.
• Volume: how many shares or contracts changed hands; it helps gauge the conviction behind a move.

Example of a simple reading

An example stock is in an uptrend on the daily chart, trades above its 50-day moving average, and pulls back to $48, a zone where it bounced twice last month. A hammer forms there on above-average volume.

Technical analysis doesn’t say “it’s going up.” It says something more useful: several reasons line up in that zone, and if price drops below $47, the idea is invalidated. With those two pieces of information you can work out the risk/reward ratio and decide whether the trade fits your trading plan.

How to start practicing

1. Learn to read bare price: candlesticks, trend, and levels, before you fill the chart with indicators.
2. Use a charting platform: most let you mark levels and try indicators for free.
3. Practice without real money: paper trading, or a simulated account, lets you apply rules without risking capital.
4. Write down your rules: what conditions you look for, where your stop loss goes, and how much you risk per trade.
5. Log every trade: a trading journal shows you what works and what doesn’t with data, not memories.

Technical vs. fundamental, and its limits

Fundamental analysis tries to estimate what an asset is worth from sales, earnings, debt, or the economy. Technical analysis looks at how price behaves. They aren’t enemies: many investors use fundamentals to choose what to buy and technicals to decide when, and where to define their risk.

Its limits are real: signals fail often, two people can read the same chart differently, and it’s easy to see patterns where there is only noise. That’s why it is practiced with written rules, risk management, and a record of results, not with gut feeling.
