Introduction
Technical analysis studies price movements and patterns to forecast future prices. Unlike fundamental analysis examining business value, technical analysis believes price movements reflect investor psychology and supply/demand dynamics.
This guide covers chart basics, common patterns, and practical technical analysis. Whether you’re timing entries or confirming fundamentals, understanding charts adds valuable perspective.
Technical analysis isn’t perfect—critics argue it’s subjective and self-fulfilling. However, charts reveal market sentiment and support/resistance levels useful for any investor.
Understanding Stock Charts
Chart Types
Line Charts:
- Simplest form
- Connects closing prices
- Shows overall trend
- Good for long-term view
Bar Charts (OHLC):
- Shows Open, High, Low, Close
- More detail than line charts
- Vertical line with horizontal ticks
- Standard for many traders
Candlestick Charts:
- Japanese origin
- Visual representation of OHLC
- Body shows open/close
- Wicks show high/low
- Color shows direction (green/red or white/black)
Candlesticks are most popular—patterns and psychology visible at glance.
Reading Candlesticks
Each candlestick shows:
Body:
- Top = Close (or Open if down)
- Bottom = Open (or Close if down)
- Green/White = Up day
- Red/Black = Down day
Wicks (Shadows):
- Top wick = High
- Bottom wick = Low
- Show price extremes
Interpreting:
- Long bodies = strong buying/selling
- Short bodies = consolidation
- Long wicks = rejection of prices
Time Frames
Charts display different time periods:
Long-Term:
- Weekly, monthly charts
- Identify major trends
- For position traders, investors
Medium-Term:
- Daily charts
- Swing trading
- Most popular time frame
Short-Term:
- Intraday (1min, 5min, 15min)

Choose time frame matching your strategy. Longer frames are more reliable.
