11. What is a Candlestick Chart?

A candlestick chart is one of the most widely used tools in technical analysis. It visually represents a stock’s Open, High, Low, and Close (OHLC) prices for a specific time period (like 5 minutes, 1 hour, 1 day, etc.) — all shown in a candle-shaped graphic.

“Each candlestick tells a story about price behaviour, market psychology, and trader sentiment — all in a single candle.”

Structure of a Candlestick

Each candle consists of two parts:

  1. The Body (Rectangle)

    • Represents the range between Open and Close prices
    • Green/White Candle: Close > Open (Bullish)
    • Red/Black Candle: Close < Open (Bearish)
  2. The Wicks or Shadows (Thin Lines Above & Below)

    • Upper wick = highest price
    • Lower wick = lowest price
