What Is Technical Analysis? Charts, Indicators and Patterns

Technical analysis studies historical price and volume data to identify patterns and forecast future price movements. The core assumption: all known information is already reflected in the price.

Candlestick Charts

Each candlestick shows four values for a time period: open, close, high and low. A green candle means the close was above the open; red means the opposite.

Candlestick patterns signal potential reversals or continuations. Key patterns: Doji (indecision), Hammer (potential bottom), Engulfing (potential reversal).

Support and Resistance

Support is a price level where buyers have historically stepped in and prevented further declines. Resistance is a level where sellers have repeatedly capped advances.

A break above resistance (with volume) is a bullish signal; a break below support is bearish. Old resistance often becomes new support after a breakout.

Key Indicators

Moving Averages (MA): 50-day and 200-day MAs identify the trend direction. A Golden Cross (50 MA crossing above 200 MA) is a classic buy signal.

RSI (Relative Strength Index): Ranges 0–100. Above 70 = overbought; below 30 = oversold. Strong trends can keep RSI extreme for extended periods.

MACD: Compares two EMAs and their signal line. A MACD line crossing above the signal line is a bullish signal; crossing below is bearish.

Frequently Asked Questions

How reliable is technical analysis?

It identifies probabilities, not certainties. Even experienced analysts are frequently wrong. Always combine with risk management (stop-losses).

Which timeframe should I use?

Day traders use 5–60 minute charts; swing traders use daily charts; long-term investors use weekly or monthly charts.

Does RSI above 70 mean the stock will fall?

Not necessarily. In strong uptrends, RSI can stay above 70 for extended periods. It is a signal to watch, not a guarantee.
