1. What Is a Stock Chart?
A stock chart is a visual representation of a company’s stock price movement over time. It shows how the stock has performed on a daily, weekly, monthly, or yearly basis. These charts help you analyze market trends, predict price movements, and make informed decisions.
2. The Basics of a Stock Chart
Key components of a stock chart:
- Price Axis (Y-Axis): Shows the stock’s price.
- Time Axis (X-Axis): Shows the timeline (daily, weekly, etc.).
- Volume Bars: Indicate how many shares were traded during a specific time period.
- Candlesticks or Lines: Represent price movement in a given time period.
3. How to Read Candlestick Charts
Candlestick charts are the most popular format among traders. Each “candle” represents:
- Open: The price when the session started.
- Close: The price at session end.
- High & Low: The highest and lowest prices within the time period.
Green candles usually mean the price increased, red means it decreased.

4. Key Indicators to Watch
Here are some indicators that help with chart reading:
- Moving Averages (MA): Shows average stock prices over a time period (e.g., 50-day MA).
- Relative Strength Index (RSI): Measures how overbought or oversold a stock is.
- MACD (Moving Average Convergence Divergence): Shows trend strength and momentum.
| Indicator | What It Measures | Common Beginner Use |
|---|---|---|
| Moving Average (MA) | Average price over a set period (e.g., 50-day) | Smoothing out noise to spot the broader trend direction |
| Relative Strength Index (RSI) | Whether a stock is overbought or oversold, on a 0–100 scale | Gauging whether a move may be overextended (conventionally, above 70 or below 30) |
| MACD | The relationship between two moving averages | Assessing trend strength and momentum shifts |
5. Spotting Trends and Patterns
Look for these patterns to predict movement:
- Uptrend: Higher highs and higher lows.
- Downtrend: Lower highs and lower lows.
- Sideways: No strong directional movement.
- Support and Resistance: Key levels where price tends to bounce or get rejected.
