Technical Analysis — What It Is and How It Works

Quick Answer

Technical analysis (TA) is a method of evaluating financial instruments using market data — mainly price and volume — rather than a company's financials. It rests on three assumptions: price discounts everything, prices move in trends, and history repeats because investor psychology is constant. Analysts read charts (line, bar, candlestick), identify support and resistance levels and trend lines, and apply indicators like RSI, MACD, moving averages, and Bollinger Bands to anticipate likely price movements. It matters because it helps decide when to buy, complementing fundamental analysis, though it is probabilistic and never works 100% of the time.

What is technical analysis?

Technical analysis (TA) is a method of evaluating financial instruments based on market data — mainly price and volume. A technical analyst doesn't study the company's financial condition (that's the domain of fundamental analysis), but looks for patterns on charts that may indicate future price movements.

Basic assumptions of TA:

1. Price discounts everything — all information is already reflected in the 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 — simplest, connects closing prices
• Bar (OHLC) — shows open, high, low and close
• Candlestick — most popular, visually clear. Green/white candle = rise, red/black = decline

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 bottoms (uptrend) or tops (downtrend). Breaking a trend line → potential direction change.

Technical indicators

Most important:

• RSI — measures overbought/oversold
• 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 formations

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

Continuation formations

• 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 looks at the same levels, the reaction is "forced"
• Requires experience in interpretation

FAQ

What does RSI above 70 actually mean?

An RSI above 70 traditionally signals an "overbought" condition — recent gains have been strong relative to recent losses. In strong uptrends, RSI can stay above 70 for extended periods, so the indicator is best treated as one input among many, not a standalone sell signal. This is educational content, not investment advice.

How is MACD different from a simple moving average?

A simple moving average smooths past prices over a fixed window, while MACD (Moving Average Convergence Divergence) shows the relationship between two exponential moving averages plus a signal line. MACD focuses on changes in trend momentum rather than the absolute trend direction, which is why crossovers are commonly used as trend-shift cues.

Does technical analysis work better on stocks or crypto?

TA tools were developed for stocks and futures but are widely applied to FX, commodities, and crypto. Markets with high liquidity and many participants tend to show cleaner patterns, while thin or manipulated markets can produce misleading signals. No instrument is guaranteed to respect any specific indicator.

Can I use technical analysis for long-term investing?

Yes — long-term investors often use weekly or monthly charts plus simple tools like 200-day moving averages to gauge broad trend direction or to time staged entries. Day-trading patterns on minute charts are generally not appropriate for buy-and-hold portfolios.

Why do TA signals sometimes fail completely?

Markets are influenced by news, macro shifts, and liquidity events that no chart pattern can predict. Patterns also become less reliable when too many participants act on the same setup, and false breakouts are a normal feature of probabilistic tools. TA improves odds in some setups but never guarantees outcomes.
