Technical Analysis — What It Is and How It Works

What is technical analysis?

Technical analysis (TA) is a method of evaluating financial instruments based on market data — mainly price and volume. Technical analysts don't study a company's financial condition (that's the domain of fundamental analysis), but look for patterns in charts that might indicate future price movements.

Quick Answer

Technical analysis (TA) is a method of evaluating financial instruments based on market data — mainly price and volume — rather than a company's financials, looking for chart patterns that might indicate future moves. It rests on three assumptions: price discounts everything, prices move in trends, and history repeats because investor psychology is constant. Core tools include support and resistance, trend lines and indicators like RSI, MACD and moving averages. TA is probabilistic, not certain. This is educational information, not investment advice.

Basic TA assumptions:

1. Price discounts everything — all information is already reflected in price
2. Prices move in trends — trends tend to continue
3. History repeats — price patterns repeat because investor psychology doesn't change

Basic tools

Charts

• Line chart — simplest, connects closing prices
• Bar chart (OHLC) — shows open, high, low, and close
• Candlestick chart — most popular, visually clear. Green/white candle = rise, red/black = fall

Support and resistance

• Support — price level below which price has difficulty falling (demand)
• Resistance — level above which price has difficulty rising (supply)

Breaking support/resistance often leads to dynamic movement in the direction of the break.

Trend lines

Connecting successive lows (uptrend) or highs (downtrend). Breaking the trend line → potential direction change.

Technical indicators

Most important:

• RSI — measures overbought/oversold conditions
• MACD — identifies trend changes
• Moving averages (SMA/EMA) — smooth price and show trend
• Bollinger Bands — measure volatility
• Volume — confirms strength of price movements

Price formations

Reversal patterns

• Head and shoulders — signal of uptrend end
• Double top / double bottom — reversal signal

Continuation patterns

• Triangle (symmetrical, ascending, descending) — consolidation before continuation
• Flag and pennant — short pause in trend

TA vs fundamental analysis

You don't have to choose — many investors combine both methods. Fundamental analysis tells you what to buy, technical analysis — when.

TA limitations

• Doesn't work 100% of the time — it's a probabilistic tool
• Self-fulfilling prophecy — if everyone watches the same levels, reaction is "forced"
• Requires experience in interpretation

FAQ

What is technical analysis in one sentence?

Technical analysis is the study of price and volume data on charts to estimate the probability of future price moves, without analysing the issuer's financial statements. It treats markets as a record of collective behaviour that tends to repeat.

What are chart patterns used for?

Chart patterns such as head and shoulders, double top, triangles or flags describe recurring shapes that historically preceded specific moves. They are used as conditional signals — entry, exit or risk-management triggers — and are not guarantees of a particular outcome.

How do RSI and MACD differ?

RSI is a momentum oscillator that flags potentially overbought or oversold conditions on a 0–100 scale. MACD compares two moving averages and is used mainly to identify shifts in trend direction or strength; many traders combine both for confirmation.

Does technical analysis work for long-term investors?

Long-term investors mostly rely on fundamentals, but technical analysis can still help with timing entries, scaling in, or setting rebalancing levels. It is a tool for decision-making, not a standalone strategy, and works best alongside a clear investment plan.

What are the main risks of relying on technical analysis?

Signals can be ambiguous, the same pattern can fail, and crowded levels can produce sharp shake-outs. Technical analysis is probabilistic by nature — using stop-losses, position sizing and risk limits is essential, and past performance does not guarantee future results.
